Can each VIF have a separate AWS side ASN? To use the Amazon Web Services Documentation, Javascript must be enabled. Then, associate your Virtual Gateway (VGW) to an AWS Direct Connect private virtual interface, or AWS Direct Connect Gateway, to make the connection. If you already have equipment located in an AWS Direct Connect location, contact the appropriate provider to complete the cross connect. For example, if you have four ports andminimum links set to four, you wont be able to delete a port from the LAG. Thanks for letting us know we're doing a good job! Q: How do I create transit virtual interface? You can view the AWS side ASN in the AWS Direct Connect console and in the response of the DescribeDirectConnectGateways or DescribeVirtualInterfaces API operations. A complete list of AWS Direct Connect locations is available on the AWS Direct Connect locations page. AWS will provide an ASN of 64512 for the AWS Direct Connect gateway if you don't choose one. You can use AWS Direct Connect gateway to access any AWS Region(except AWS Regions in China) from any AWS Direct Connect location. 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. Q: Youre out of ports and I have to order a new LAG, but I have Virtual Interfaces (VIFs) configured. 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. Q: How does AWS Direct Connect differ from an IPsec VPN Connection? If you've got a moment, please tell us what we did right so we can do more of it. Q: What are local preference communities for private and transit virtual interfaces (VIFs)? You must advertise public IP prefixes (/31or smaller) that you ownor are AWS-providedvia BGP. This will prevent all network traffic flowing over that virtual interface until you reduce the number of routes to less than 100. Q: Are link aggregation groups (LAG) in active/active or active/passive mode? Avoid relying on a single on-premises device connecting to a single AWS Direct Connect device. No, VLANs are used in AWS Direct Connect only to separate traffic between virtual interfaces. Q: Can I associate AWS Transit Gateway that are owned by any AWS account with an AWS Direct Connect gateway that is owned by any AWS account? the appropriate number of dedicated connections in multiple locations. What happens if I detach one of the VGW from the VPC? You must request another port for your LAG. Customers can get 1Gbps or 10Gbps Dedicated Connections or work with an approved partner for Hosted Connections with capacities ranging from 50Mbps to 10Gbps. Yes, you can associate VPCs owned by any AWS account with an AWS Direct Connect gateway owned by any AWS account. 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. Pricing is per port-hour consumed for each port type. 802.1AE MAC Security (MACsec) is an IEEE standard that provides data confidentiality, data integrity, and data origin authenticity. Q: Can I terminate my tunnel to an endpoint with an IPv6 address? An AWS Direct Connect link to AWS Local Zones works the same way as connecting to a Region. Q: What is the difference between dedicated and hosted connections? MACsec is supported on 10 Gbps and 100 Gbps dedicated AWS Direct Connect connections at selected points of presence. Q: Can I have v4 and v6 BGP sessions running over a single VPN tunnel? This can be accomplished by advertising prefixes over the primary/active virtual interface with a community for higher local preference than prefixes advertised over the backup/passive virtual interface. To establish a connection usingAWS Direct Connect SiteLink, you must enable AWS Direct Connect SiteLink at two or more VIFs at two or more AWS Direct Connect locations. If no ports are available in the same device, you must order a new LAG and migrate your connections. Q: Can I mix interface types and have a few 1 G ports and a few 10 G ports in the same LAG? Q: What is the AWS Direct Connect Resiliency Toolkit? If you are using a public ASN, you must own it. Q: Does AWS act as my "first mile" or "last mile" provider to connect my on-premises locations to AWS? 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). Q: Can I use AWS Direct Connect and a VPN Connection to the same VPC simultaneously? Private virtual interfaces and AWS Direct Connect gateways must be in the same AWS account. Amazon Web Services (AWS) offers customers the ability to achieve highly resilient network connections between Amazon Virtual Private Cloud (Amazon VPC) and their on-premises infrastructure. The VPC Virtual Private Gateway (VGW) ID AWS will allocate private IPs (/30) in the 169.x.x.x range for the BGP session and will advertise the VPC CIDR block over BGP. How can I make this change? Cloud WAN, currently in preview, can create and manage networks of VPCs across multiple Regions. Q: What are the technical requirements for virtual interfaces (VIF) to VPCs? 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. Can local preference communities be used to balance traffic in this scenario? Traffic will ingress to the parent Region first before connecting back to your AWS Local Zones. Q: Which type of AWS Direct Connect connections support MACsec? The AWS side ASN for VIF is inherited from the AWS side ASN of the attached AWS Direct Connect gateway. Your device configuration also must change appropriately. Yes. AWS Direct Connect Partners can help you extend your preexisting data center or office network to a AWS Direct Connect location. 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. Q: What is the AWS Direct Connect Failover Testing feature? However, it will not protect against a single device failure at AWS where your LAG is terminating. 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. AWS has set the BFD liveness detection minimum interval to 300, and the BFD liveness detection multiplier to 3. In the case of a transit virtual interface, the AWS account that owns the Amazon Virtual Private Cloud(s) attached to the AWS Transit Gateway associated with the AWS Direct Connect gateway attached to the transit virtual interface is charged. Q: Can you create a tool to move my virtual interfaces (VIFs) for me? You can use AWS Direct Connect gateway to access any AWS Region (except AWS Regions in China) from any AWS Direct Connect locations. No, data transfer between Availability Zones in a Region will be billed at the regular Regional data transfer rate in the same month in which the usage occurred. Please refer to your browser's Help pages for instructions. RFC 3021 (Using 31-Bit Prefixes on IPv4 Point-to-Point Links) is supported on all Direct Connect virtual interface types. Q: Can themaximum transmission unit of a LAG change? Q: Can I use different private ASNs for my AWS Direct Connect Gateway and Virtual Private Gateway? 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. It will not be available for hosted connections. Please see AWS Direct Connect Partnersfor more information. Please refer to AWS Direct Connect quotas pageto learn more about the limits associated with transit virtual interface. However, you cannot attach an AWS Direct Connect gateway (DXGW) to an AWS Transit Gateway when the AWS Direct Connect gateway was previously associated with a virtual private gateway, or is attached to a private virtual interface. All commercial AWS Regions (except AWS China Region) and AWS GovCloud (US). To do this, you need 4x 10 GE interfaces on your router to connect to AWS. Q: Can I convert a LAG back to individual ports? No, a LAG doesn't make your connectivity to AWS more resilient. No, an AWS Direct Connect Gateway can only have one type of virtual interface attached. Yes. Q: What does a simple two-site network architecture look like with AWS Direct Connect SiteLink? Q: How does AWS Direct Connect work with consolidated billing? Yes. Yes, you can resize the VPC. Q: Where and how do I configure AWS Direct Connect SiteLink? To do this, you must create a new private virtual interface, and at the time of creation, associate it with your AWS Direct Connect gateway. Q: Can I use any ASN - public and private? Please note this will cause your ports to go down for a moment while they are reconfigured as a LAG. Q: Can I use this feature for my existing EBGP sessions? Configurable Private Autonomous System Number (ASN). Q: Can I send traffic from a VPC that is associated with an AWS Direct Connect gateway to another VPC associated to the same AWS Direct Connect gateway? 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. No. To use AWS Direct Connect SiteLink, you must connect AWS Direct Connect SiteLink-enabled virtual interfaces (VIFs) to an AWS Direct Connect gateway. Refer to the MAC Security section of our user guide to verify supported operation modes and required MACsec features. 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. Discover more AWS Direct Connect resources. With AWS Direct Connect, you will pay AWS Direct Connect data transfer rates for origin transfer. Maximum resilience is achieved by separate connections terminating on separate devices in more than one location. See the AWS Direct Connect pricing page for details. You can associate multiple virtual private gateways (VGWs, associated with a VPC) to an AWS Direct Connect gateway, as long as the IP CIDR blocks of the Amazon VPC associated with the Virtual Private Gateway do not overlap. For customers with a Japanese billing address, use of AWS services is subject to Japanese Consumption Tax. 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? A new unused VLAN tag that you select. AWS Regions provide multiple physically separated and isolated It will show as a single dxlag and well list the connection ids under it. When the AWS Direct Connect SiteLink feature is enabled at two or more AWS Direct Connect locations, you can send data between those locations, bypassing AWS Regions. No, AWS Direct Connect gateway does not break AWS VPN CloudHub. You can choose any private ASN. If you have three or more then the bundle is active and will pass traffic if you have a VIF configured. An AWS Direct Connect gateway is a globally available resource. We will return a notification with the specific panel/port youve deleted and a reminder to disconnect the cross connect and circuit from AWS. A configurable private autonomous system number (ASN) makes it possible to set the ASN on the AWS side of the Border Gateway Protocol (BGP) session for private or transit VIFs on any newly created AWS Direct Connect Gateway. AWS recommends customers use multiple dynamically routed, rather than statically routed, connections to AWS at multiple AWS Direct Connect locations. Q: Can I use the same private network connection with Amazon Virtual Private Cloud (VPC) and other AWS services simultaneously? You associate an AWS Direct Connect gateway with the virtual private gateway for the VPC. Q: I have private VIFs already configured and want to set a different AWS side ASN for the BGP session on an existing VIF. You should also cancel any service(s) purchased by a third party. You will need a MACsec-capable device on your end of the Ethernet connection to an AWS Direct Connect location. See AWS Direct Connect Partnersfor more information. Q: Can I attach private virtual interface to my AWS Transit Gateway? Q: When I associate my existing AWS Direct Connect connection with a LAG, what happens with virtual interfaces (VIFs) already created with a connection? operate applications and databases that automatically fail over between Availability Zones without interruption. Highly resilient connections requireredundant hardware, even when connecting from the same physical location. 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. You can cancel the test while it is running. 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. The AWS Direct Connect Resiliency Toolkit provides a connection wizard that helps you choose between multiple resiliency models. This is available in all commercial AWS Regions (except AWS China Region) and AWS GovCloud (US). Q: How can I get started with AWS Direct Connect? For details on creating, updating, associating/disassociating, and deleting a LAG refer to the AWS Direct Connect documentation: Link aggregation groups - AWS Direct Connect. You can select your own private ASN in the AWS Direct Connect gateway console. After you have downloaded your Letter of Authorization and Connecting Facility Assignment (LOA-CFA), you must complete your cross-network connection. Dynamic LACP bundles are used; static LACP bundles are not supported. Q: Can I extend one of my VLANs to the AWS Cloud using AWS Direct Connect? For additional resiliency, customers can also explore the use of multi-region failover. You cannot assign any other public ASN. AWS support for Internet Explorer ends on 07/31/2022. Q: Do you require the use of Extended Packet Numbering (XPN)? AWS is not validating ownership of the ASNs, therefore we're limiting the AWS side ASN to private ASNs. Using the AWS Direct Connect Resiliency Toolkit to get started. For AWS Direct Connect pricing information, Refer to the AWS Direct Connect pricing page for more detailed information. Q: Are there any setup charges or a minimum service term commitment required to use AWS Direct Connect? LAG will only include ports on the same AWS Direct Connect devices. Similar to the private virtual interface, you can establish one IPv4 BGP session and one IPv6 BGP session over a single transit virtual interface. VIFs on two different LAGs can be connected to the same VGW. After selecting a resiliency model, the AWS Direct Connect Resiliency Toolkitcan guide you through the process of ordering redundant connections. At this time, we only support IPv4 endpoint address for VPN. 2022, Amazon Web Services, Inc. or its affiliates. Q: What happens if I advertise more than 100 routes over a Border Gateway Protocol session? If you want to limit traffic to and from any specific VPC, you should consider using Access Control Lists (ACLs) for each VPC. A public virtual interface enables access to public services, such as Amazon S3. 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. Depending on your use case, you might choose one, the other, or both. Once the AWS Direct Connect gateway owner approves the new proposal, the resized VPC CIDR will be advertised towards your on-premises network. Q: Can you attach a private virtual interface (VIF) to more than one AWS Direct Connect gateway? Maximum Resiliency: You can achieve maximum resiliency for critical workloads by using separate connections that terminate on separate All rights reserved. For Dedicated Connections, 1 Gbps, 10 Gbps, and 100 Gbps ports are available. Yes, you can run tests for the Border Gateway Protocol session(s) established using any type of virtual interface. Path MTU discovery is supported and recommended. Q: Will this feature be available on both Public and Private Virtual Interfaces? Q: If I have a public ASN, will it work with a private ASN on the AWS side? How long do you keep the test history? Yes. You select a resiliency model, and then the AWS Direct Connect Resiliency Toolkit guides you through the dedicated connection ordering process. Note that these capacity identifiers will appear by location depending on which Hosted Connection capacities you have at each location.
