AWS Direct Connect follows the standard approach for path selection. Q: I'm attaching multiple Virtual Private Gateways with their own private ASN to a single AWS Direct Connect gateway configured with its own private ASN. With the introduction of the granular Data Transfer Out allocation feature, the AWS account responsible for the Data Transfer Out will be charged for the Data Transfer Out performed over a transit/private virtual interface. Q: Once the AWS Direct Connect gateway is created, can I change or modify the AWS side ASN? A transit virtual interface can only be attached to an AWS Direct Connect gateway. Yes, you can use different private ASNs for your AWS Direct Connect Gateway and Virtual Private Gateway. Q: Is there any difference to the BGP configuration/setup details outlined for AWS Direct Connect? To enable this use case, you must create a VPN in the AWS Region of the VIF and attach the VIF and the VPN to the same VGW. You can assign any private ASN to the AWS side. For AWS Direct Connect pricing information, Refer to the AWS Direct Connect pricing page for more detailed information. To achieve high availability connectivity to AWS, we recommend making connections at multiple AWS Direct Connect locations. Yes. We suggest you create the new VIFs on your new LAG, and then move the connections over to the new LAG once youve created all of your VIFs. You can check if your existing connection is MACsec-capable through the AWS Management Console or by using the DescribeConnectionsAWS Direct Connect API. If you've got a moment, please tell us what we did right so we can do more of it. However, due to security practices, your equipment cannot be placed within AWS Direct Connect rack or cage areas. Last, the Single flow limit (5-tuple) for connectivity to an AWS Local Zone is approximately 2.5 Gbps at maximum MTU (1468) compared to 5 Gbps at the Region. This will prevent all network traffic flowing over that virtual interface until you reduce the number of routes to less than 100. Q: What is an AWS Direct Connect Gateway Bring your own private ASN? Customers can get 1Gbps or 10Gbps Dedicated Connections or work with an approved partner for Hosted Connections with capacities ranging from 50Mbps to 10Gbps. Q: Can I use the same private network connection with Amazon Virtual Private Cloud (VPC) and other AWS services simultaneously? Q: What does a simple two-site network architecture look like with AWS Direct Connect SiteLink? Depending on your use case, you might choose one, the other, or both. When selecting AWS Direct Connect Partners, consider a dual-vendor approach, if financially feasible, to ensure private-network diversity. This is available in all commercial AWS Regions (except AWS China Region) and AWS GovCloud (US). To connect to a Region, first extend your VPC from the parent Region into AWS Local Zones by creating a new subnet and assigning it to the AWS Local Zone. Q: I am working with an AWS Direct Connect Partner to get private virtual interface (VIF) provisioned for my account, can I use an AWS Direct Connect gateway? Thus, we do not recommend customers use AWS Site to Site VPN as a backup for AWS Direct Connect connections with speeds greater than 1 Gbps. Once the AWS Direct Connect gateway is configured with an AWS side ASN, the private virtual interfaces associated with the AWS Direct Connect gateway use your configured ASN as the AWS side ASN. RFC 3021 (Using 31-Bit Prefixes on IPv4 Point-to-Point Links) is supported on all Direct Connect virtual interface types. Q: Does AWS Direct Connect SiteLink require an AWS Direct Connect gateway connection? Q: Does AWS Direct Connect SiteLink support IPv6? Q: What are the supported local preference communities for an AWS Direct Connect private virtual interface? We offer MACsec as an encryption option you can integrate into your network in addition to other encryption technologies you currently use. Q: Will this feature work with an AWS Direct Connect gateway? We preserve your test history for 365 days. Highly resilient, fault-tolerant network connections are key to a well-architected system. Development and Test: You can achieve development and Q: Can I convert a LAG back to individual ports? Q: Where and how do I configure AWS Direct Connect SiteLink? You can share a private virtual interface to interface with up to 10 VPCs to reduce the number of Border Gateway Protocol sessions between your on-premises network and AWS deployments. See the AWS GovCloud (US) User Guide for detailed instructions on setting up AWS Direct Connect for use with the AWS GovCloud (US) Region. Yes, you can continue to use supported BGP attributes (AS_PATH, Local Pref, NO_EXPORT) on the transit virtual interface. Your device must support 802.1Q VLANs. In order to send traffic between two VPCs, you must configure a VPC peering connection. You can use AWS Direct Connect gateway to access any AWS Region(except AWS Regions in China) from any AWS Direct Connect location. Yes. Please refer to AWS Direct Connect User Guideto review supported and not supported traffic patterns. Yes, provided the current AWS Direct Connect Gateway is not associated with an AWS Transit Gateway. Yes, you can use this feature to influence egress traffic behavior between two VIFs on the same physical connection. Ifminimum links are set to three, you can then delete a port from the LAG. Q: Can I use AWS Direct Connect to reach resources running in AWS Local Zones? In other words, AWS ports send Link Aggregation Control Protocol Data Units (LACPDUs) continuously. With global access for AWS Direct Connect, you can reach AWS resources in any global AWS region using global public VIFs and Direct Connect gateway. MACsec is not supported on 1 Gbps dedicated connections or any hosted connections. A single 40 GE interface connecting to a 4x 10 GE LACP is not supported. When planning your connectivity, work with your selected Partner(s) to determine which of the above best practices are right for your needs, and learn how your selected Partner(s) can enable you to achieve them. If you want to limit traffic to and from any specific VPC, you should consider using Access Control Lists (ACLs) for each VPC. LAGs streamline configuration because the LAG configuration applies to all connections in the group. Q: I currently have a VPN in us-east-1 attached to a virtual private gateway (VGW). NOTE: The limitations on MTU size and single flow do not apply to AWS Direct Connect connectivity to the AWS Local Zone in Los Angeles. You can advertise the default route via BGP. A new unused VLAN tag that you select. To improve failover times between paths when using multiple LAGs, bidirectional forwarding detection (BFD) is supported. To create a hub-and-spoke architecture, create an AWS Direct Connect gateway and associate it with all AWS Direct Connect SiteLink-enabled private VIFs. Q: Does AWS Direct Connect SiteLink support MACsec? AWS Direct Connect SiteLink requires BGP. One such implementation is explained in thisblog. Q: Which type of AWS Direct Connect connections support MACsec? You can change theminimum links value after youve set up the bundle, either using the AWS Management Console or using an API. Except as otherwise noted, our prices are exclusive of applicable taxes and duties, including VAT and applicable sales tax. Q: Why can't I assign a public ASN for the AWS half of the BGP session? For specific instructions for each provider and cross connect pricing, refer to the AWS Direct Connect documentation: Requesting cross connects at AWS Direct Connect locations. No, you need to make connections between the local service providers used at your on-premises locations to connect to AWS. You can also consider multi-region failover with Transit Gateway Cross Region Peering and Direct Connect Gateway. The location preference communities for private and transit virtual interfaces provides a feature to let you influence the return path for traffic sources from VPC(s). If you've got a moment, please tell us how we can make the documentation better. The VIF type can be private or transit. The following communities are supported for private virtual interface and are evaluated in order of lowest to highest preference. Maximum resilience is achieved by separate connections terminating on separate devices in more than one location. Q: Can I associate VPCs owned by any AWS account with an AWS Direct Connect gateway owned by any AWS account? AWS Direct Connect Partners can help you extend your preexisting data center or office network to a AWS Direct Connect location. All AWS Direct Connect locations give access to all global AWS Regions (except China) as shown in our region table. No, at this time we do not provide such monitoring features. To get started with planning your connectivity to AWS, visit our Getting Started page. Note that these capacity identifiers will appear by location depending on which Hosted Connection capacities you have at each location. Q: How do I request a cross connect at an AWS Direct Connect location? If you are using a last-mile connectivity partner, check that your last-mile connection can support MACsec. You select a resiliency model, and then the AWS Direct Connect Resiliency Toolkit guides you through the dedicated connection ordering process. Yes, as long as the VPC route table has routes to the virtual private gateway (VGW) towards the VPN. You can use AWS Direct Connect connections that support MACsec to encrypt your data from your on-premises network or collocated device to your chosen AWS Direct Connect point of presence. Yes, but only for failover. We're sorry we let you down. Themaximum transmission unit of the LAG can be changed. Q: If I have only two ports in my LAG can I still delete one? This can reduce the number of Border Gateway Protocol sessions between your on-premises network and AWS deployments. If you delete the virtual interface, your test history is also deleted. How long do you keep the test history? The AWS side ASN you receive depends on your private virtual interface association. You can use an AWS Direct Connect gateway attached with one or more transit virtual interfaces to interface with up to three AWS Transit Gateways in any supported AWS Regions. Make sure your VPN connections can handle the failover traffic from AWS Direct Connect. They will not come back up until LAG is configured on your side. Q: Can I attach a virtual private gateway (VGW) to an AWS Direct Connect gateway if it is not attached to a VPC? AWS is not validating ownership of the ASNs, therefore we're limiting the AWS side ASN to private ASNs. Q: Does the LAG show as a single connection or a collection of connections? No. Yes, but only if yourminimum links are set to lower than the remaining ports. Q: Are there any setup charges or a minimum service term commitment required to use AWS Direct Connect? If you resize your VPC, you must resend the proposal with the resized VPC CIDR to the AWS Direct Connect gateway owner. It can take up to 40 minutes to establish an association between AWS Transit Gateway and AWS Direct Connect gateway. The following local preference BGP community tags are supported: 7224:7100 - Low preference 7224:7200 - Medium preference 7224:7300 - High preference. Q: Which AWS account gets charged for the Data Transfer Out performed over a public virtual interface? The AWS Direct Connect Failover Testing feature allows you to test the resiliency of your AWS Direct Connect connection by disabling the Border Gateway Protocol session between your on-premises networks and AWS. Click here to return to Amazon Web Services homepage, AWS Direct Connect Resiliency Recommendations. On billing statements, charges related to AWS Direct Connect SiteLink will appear on a separate line from other AWS Direct Connect-related charges. Q: What types of virtual interfaces (VIFs) are supported by AWS Direct Connect SiteLink? To avoid this situation, the IEEE Std 802.1AEbw-2013 amendment introduced extended packet numbering, increasing the numbering space to 64-bits, easing the timeliness requirement for key rotation. Q: I have created an AWS Direct Connect gateway with one AWS Direct Connect VIF, and three non-overlapping VGW-VPC pairs, what happens if I detach one of the virtual private gateways (VGW) from the AWS Direct Connect gateway? As with any AWS Direct Connect location, this locations conforms to the standard resiliency model that includes two customer facing devices per location that allow customers to establish locally resilient and redundant physical connectivity to the Amazon backbone network. You will need the following information to complete the connection: A public or private ASN. To do this, you need 4x 10 GE interfaces on your router to connect to AWS. If you are configuring a virtual interface to the public AWS Cloud, the IP addresses for both ends of the connection must be allocated from public IP space that you own. VPN BGP will work the same as AWS Direct Connect. Networking features, such as Elastic File System, Elastic Load Balancing, Application Load Balancer, Security Groups, Access Control List, and AWS PrivateLink, work with AWS Direct Connect gateway. Similarly, transit virtual interfaces and AWS Direct Connect gateways must be in the same AWS account. You can access this using public virtual interfaces on AWS Direct Connect connection. After the configured test duration, we restore the Border Gateway Protocol session between your on-premises networks and AWS using the Border Gateway Protocol session parameters negotiated before starting the test. Q: Do I need a new AWS Direct Connect connection to use MACsec with my MACsec-capable device? Services provided by AWS Direct Connect Partners may have other terms or restrictions that apply. Q: How do I set up AWS Direct Connect for the AWS GovCloud (US) Region? For redundancy, you must use two or more AWS Direct Connect connections. If you already have equipment located in an AWS Direct Connect location, contact the appropriate provider to complete the cross connect. Q: When I associate my existing AWS Direct Connect connection with a LAG, what happens with virtual interfaces (VIFs) already created with a connection? For additional resiliency, AWS customers can consider using AWS Site to Site VPN terminating on an AWS Transit Gateway as a back up to their AWS Direct Connect connections. Javascript is disabled or is unavailable in your browser. Q: Are there limits on the amount of data that I can transfer using AWS Direct Connect? Q: If I have established IPv4 and IPv6 Border Gateway Protocol sessions, can I run this test for each Border Gateway Protocol session? Please refer to AWS Direct Connect quotas pageto learn more about the limits associated with transit virtual interface. Q: If I use an AWS Direct Connect gateway, does my traffic to the desired AWS Region go by way of the associated home AWS Region? AWS Direct Connect gateway enables connectivity between on-premises networks and VPCs in any AWS Region. If the virtual interface is connected to a VPC, and you choose to have AWS automatically generate the peer IP CIDR, the IP address space for both ends of the connection is allocated by AWS and is in the 169.254.0.0/16 range. Yes, you can configure the AWS side of the BGP session with a private ASN and your side with a public ASN. No. All rights reserved. Q: Can I delete a single port from my LAG? Q: Are link aggregation groups (LAG) in active/active or active/passive mode? AWS Direct Connect bypasses the internet; instead, it uses dedicated, private network connections between your network and AWS. Q: How will I be charged and billed for my use of AWS Direct Connect? Then create an AWS Direct Connect gateway and associate each of your AWS Direct Connect SiteLink-enabled VIFs with it in order to create a network. Q: Can I run failover tests for any type of virtual interface? devices in more than one location. It also helps prevent a complete location failure. All commercial AWS Regions (except AWS China Region) and AWS GovCloud (US). In many circumstances, private network connections can reduce costs, increase bandwidth, and provide a more consistent network experience than internet-based connections. Supported browsers are Chrome, Firefox, Edge, and Safari. Q: Where is AWS Direct Connect available? Q: How do I implement a hub-and-spoke architecture with AWS Direct Connect SiteLink? The LAG at your endpoint can be configured with LACP active or passive modes. Yes, you can associate a provisioned private virtual interface (VIF) with your AWS Direct Connect gateway when you confirm that you are provisioned as private in your AWS account. This feature is an additional knob you can use to get better control over the incoming traffic from AWS. AWS Direct Connect SiteLink-enabled VIFs on an AWS Direct Connect gateway cannot communicate with AWS Direct Connect SiteLink-enabled VIFs on another AWS Direct Connect gateway, creating a segmented network. It is important to understand that AWS Site to Site VPN supports up to 1.25 Gbps throughput per VPN tunnel and does not support Equal Cost Multi Path (ECMP) for egress data path in the case of multiple AWS Site to Site VPN tunnels terminating on the same VGW. AWS Direct Connect SiteLink works with both hosted and dedicated connections. Dynamic LACP bundles are used; static LACP bundles are not supported. When requesting a connection, you will be asked to select a AWS Direct Connect location, the number of ports, and the port speed. The AWS side ASN you receive depends on your private virtual interface association. Q: I have an existing private virtual interface associated with virtual private gateway (VGW), can I associate my existing private virtual interface with an AWS Direct Connect gateway? If you have more than one link in your LAG, and if your minimum links are set to one, your LAG will let you protect against single link failure. How do I move those? The maximum number of links is 4x in a LAG group. This setting cannot be changed. Similar to the private virtual interface, you can establish one IPv4 BGP session and one IPv6 BGP session over a single transit virtual interface. Q:What defines billable port-hours for Hosted Connections? For additional resiliency, customers can also explore the use of multi-region failover. For Dedicated Connections, 1 Gbps, 10 Gbps, and 100 Gbps ports are available. A transit virtual interface is a type of virtual interface you can create on any AWS Direct Connect connection with a capacity of 1 Gbps or more (1/2/5/10/100 Gbps). Using AWS Direct Connect, data that would have previously been transported over the internet is delivered through a private network connection between your facilities and AWS. Once deployed, you can connect your equipment to AWS Direct Connect using a cross-connect. The AWS side is always configured as active mode LACP. Q: How does AWS Direct Connect differ from an IPsec VPN Connection? We will ask you to re-enter a private ASN once you attempt to create the AWS Direct Connect gateway. Q: What are the technical requirements for virtual interfaces to public AWS services, such as Amazon EC2 and Amazon S3? No, we will continue to respect AS_PATH attribute. Please see AWS Direct Connect Partnersfor more information. Yes, you can create one transit virtual interface on any connection of capacity of 1 Gbps or more (1, 2, 5, 10, 100 Gbps). Q: Can I use same private ASNs for my AWS Direct Connect Gateway and Virtual Private Gateway? After you have downloaded your Letter of Authorization and Connecting Facility Assignment (LOA-CFA), you must complete your cross-network connection. Q: Who can initiate a failover test using the AWS Direct Connect Resiliency Toolkit? As shown in the figure above, such a topology helps in the case of the device failure at a location but does not help in the event of a total location failure. You can associate up to three Transit Gateway to an AWS Direct Connect gateway as long as the IP CIDR blocks announced from your Transit Gateways do not overlap. Q: How do I create a segmented network architecture with AWS Direct Connect SiteLink? For information about how to use VPN with AWS Direct Connect, see AWS Direct Connect Plus VPN. Your device configuration also must change appropriately. Q: How can I configure/assign my ASN to be advertised as the AWS side ASN? Q: What IP address will be assigned to each end of a virtual interface? To order a port to connect to AWS GovCloud (US) you must use the AWS GovCloud (US) Management Console. Yes. Q: Can I set link priority on a specific link? Port charges will continue to be billed as long as the Hosted Connection is provisioned for your use. Q: What is the AWS Direct Connect Resiliency Toolkit? The AWS side ASN for VIF is inherited from the AWS side ASN of the attached AWS Direct Connect gateway. It will show as a single dxlag and well list the connection ids under it. Click here to return to Amazon Web Services homepage, A complete list of AWS Direct Connect locations is available on the AWS Direct Connect, For AWS Direct Connect pricing information, Refer to the AWS Direct Connect. Q: I have two private VIFs on a physical connection at an AWS Direct Connect location; can I use supported communities to influence egress behavior across these two private VIFs? To use the Amazon Web Services Documentation, Javascript must be enabled. If your existing MACsec connection is not terminated on a MACsec-capable device, you can request a new MACsec-capable connection using the AWS Management Console or the CreateConnection API. No, one private virtual interface can only attach to one AWS Direct Connect gateway OR one Virtual Private Gateway. An AWS Direct Connect gateway is a grouping of virtual private gateways (VGWs) and private virtual interfaces (VIFs). Q: Does AWS Direct Connect offer a Service Level Agreement (SLA)? Q: Can I use this feature for my existing EBGP sessions? Q: If I have a public ASN, will it work with a private ASN on the AWS side? Traffic from your on-premises network to the detached VPC will stop, and VGW's association with the AWS Direct Connect gateway will be deleted. Traffic will ingress to the parent Region first before connecting back to your AWS Local Zones. No, you cannot do this with an AWS Direct Connect gateway, but the option to attach a VIF directly to a VGW is available to use the VPN <-> AWS Direct Connect AWS VPN CloudHub use case. You can use AssociateVirtualInterface API or console to do this operation. Q: Can you attach a private virtual interface (VIF) to more than one AWS Direct Connect gateway? You will pay applicable egress data charges based on the source remote AWS Region and port hour charges. Each AWS Direct Connect connection can be configured with one or more virtual interfaces. Q: When should I use AWS Direct Connect SiteLink and when should I use AWS Cloud WAN? Q: What is an AWS Direct Connect gateway? You can configure your VIF to enable or disable AWS Direct Connect SiteLink using the AWS Management Console, AWS Command Line Interface, or APIs. Q: I use AWS VPN CloudHub today. Dynamic routing also enables remote connections to automatically leverage available preferred routes, if applicable, to the on-premises network. Hosted connections are sourced from a AWS Direct Connect Partner that has a network link between themselves and AWS. With AWS Direct Connect Gateway, you can access any AWS Region from any AWS Direct Connect Location (excluding China). For example, consider the bill for a customer with two separate 200 Mbps Hosted Connections at an AWS Direct Connect location, and no other Hosted Connections at that location. No, VLANs are used in AWS Direct Connect only to separate traffic between virtual interfaces. Q: What is the default behavior, in case I do not use the supported communities? You must create a new DXGW and associate it with the VGW. Q: How do I add links to my LAG once its set up? 802.1AE MAC Security (MACsec) is an IEEE standard that provides data confidentiality, data integrity, and data origin authenticity. Q:Does AWS Direct Connect SiteLink require BGP? All rights reserved. High Resiliency: You can achieve high resiliency for Yes, all existing BGP sessions on private virtual interfaces support the use of local preference communities. For a month with 720 total hours, the port-hour total for this item will be 1,440, or the total number of hours in the month multiplied by the total number of 200 Mbps Hosted Connections at this location. Link aggregation groups - AWS Direct Connect, AWS Direct Connect Resiliency Recommendations, Extend a VPC to a Local Zone, Wavelength Zone, or Outpost, Learn more about AWS Direct Connect limits, AWS Direct Connect pricing page for details, AWS Direct Connect resiliency recommendations. Once a transit VIF is connected to an AWS Direct Connect Gateway, that Gateway cannot also host another Private VIF - it is dedicated to the transit VIF. I would like to receive all traffic for this destination across the 10 Gbps AWS Direct Connect connection, but still be able to failover to the 1 Gbps connection. You can purchase rack space within the facility housing the AWS Direct Connect location and deploy your equipment nearby. Q: Can I add more transit virtual interfaces to the connection? For publicly addressable AWS resources (for example, Amazon S3 buckets, Classic EC2 instances, or EC2 traffic that goes through an internet gateway), if the outbound traffic is destined for public prefixes owned by the same AWS payer account and actively advertised to AWS through an AWS Direct Connect public virtual Interface, the Data Transfer Out (DTO) usage is metered toward the resource owner at the AWS Direct Connect data transfer rate. You can use AWS Direct Connect gateway to access any AWS Region (except AWS Regions in China) from any AWS Direct Connect locations. In such situation, egress behavior across multiple VIFs from multiple AWS Direct Connect Locations may be arbitrary. Consider using AWS Site to Site VPN terminating on an AWS Transit Gateway as a backup for your mission critical workloads. Q: If I have a virtual private gateway (VGW) attached to a VPN and an AWS Direct Connect gateway, and my AWS Direct Connect circuit goes down, will my VPC traffic route out to the VPN? When designing remote connections, consider using redundant hardware and telecommunications providers. AWS recommends customers use multiple dynamically routed, rather than statically routed, connections to AWS at multiple AWS Direct Connect locations. Yes, AWS Direct Connect gateway offers a way for you to selectively announce prefixes towards your on-premises networks. Q: How do I enable BFD on my AWS Direct Connect connection? AWS recommends connecting from multiple data centers for physical location redundancy. Q: What are the quotas associated with an AWS Direct Connect gateway? Q: Do you support the use of Secure Channel Identifier (SCI)? You can also connect to AWS Local Zones. If using an AWS Direct Connect Partner to facilitate an AWS Direct Connect connection, contact the AWS Direct Connect Partner regarding any fees they may charge. If you are using a public ASN, you must own it. If no ports are available in the same device, you must order a new LAG and migrate your connections. Prefixes belonging to CloudFront locations that are not inside the Amazon backbone network will not be advertised through Direct Connect. You can view the AWS side ASN in the AWS Direct Connect console and in the response of the DescribeDirectConnectGateways or DescribeVirtualInterfaces API operations. You will need a MACsec-capable device on your end of the Ethernet connection to an AWS Direct Connect location. This will allow remote connections to fail overautomatically. AWS Direct Connect SiteLink, on the other hand, connects DX locations together, bypassing AWS Regions to improve performance. The resiliency models are designed to ensure that you have You must create a new AWS Direct Connect gateway with desired ASN, and create a new VIF with the newly created AWS Direct Connect gateway. This feature is backward compatible with pre-existing methods for achieving failover; if your connection is currently configured for failover, no additional changes are necessary. Click here to return to Amazon Web Services homepage, AWS Direct Connect launches third location in New York Metro Area. No, this feature is currently available for private and transit virtual interfaces only. We support 32-bit ASNs from 4200000000 to 4294967294. Q: I have private VIFs already configured and want to set a different AWS side ASN for the BGP session on an existing VIF. No, an AWS Direct Connect Gateway can only have one type of virtual interface attached. We want to protect customers from BGP spoofing. critical workloads by using two single connections to multiple locations.
