Adding or deleting a BGP peer - AWS Direct Connect

Adding or deleting a BGP peer

Add or delete an IPv4 or IPv6 BGP peering session to your virtual interface.

A virtual interface can support a single IPv4 BGP peering session and a single IPv6 BGP peering session.

You cannot specify your own peer IPv6 addresses for an IPv6 BGP peering session. Amazon automatically allocates you a /125 IPv6 CIDR.

Multiprotocol BGP is not supported. IPv4 and IPv6 operate in dual-stack mode for the virtual interface.

AWS enables MD5 by default. You cannot modify this option.

Adding a BGP peer

Use the following procedure to add a BGP peer.

To add a BGP peer

  1. Open the AWS Direct Connect console at https://console.aws.amazon.com/directconnect/v2/home.

  2. In the navigation pane, choose Virtual Interfaces.

  3. Select the virtual interface and then choose View details.

  4. Choose Add peering.

  5. (Private virtual interface) To add IPv4 BGP peers, do the following:

    • Choose IPv4.

    • To specify these IP addresses yourself, for Your router peer ip, enter the destination IPv4 CIDR address to which Amazon should send traffic. For Amazon router peer ip, enter the IPv4 CIDR address to use to send traffic to AWS.

  6. (Public virtual interface) To add IPv4 BGP peers, do the following:

    • For Your router peer ip, enter the IPv4 CIDR destination address where traffic should be sent.

    • For Amazon router peer IP, enter the IPv4 CIDR address to use to send traffic to AWS.

  7. (Private or public virtual interface) To add IPv6 BGP peers, choose IPv6. The peer IPv6 addresses are automatically assigned from Amazon's pool of IPv6 addresses; you cannot specify custom IPv6 addresses.

  8. For BGP ASN, enter the The Border Gateway Protocol Autonomous System Number of your on-premises peer router for the new virtual interface.

    For a public virtual interface, the ASN must be private or already on the allow list for the virtual interface.

    The valid values are 1-2147483647.

    Note that if you do not enter a value, AWS automatically assigns one.

  9. To provide your own BGP key, for BGP Authentication Key, enter your BGP MD5 key.

  10. Choose Add peering.

Deleting a BGP peer

If your virtual interface has both an IPv4 and IPv6 BGP peering session, you can delete one of the BGP peering sessions (but not both).

To delete a BGP peer

  1. Open the AWS Direct Connect console at https://console.aws.amazon.com/directconnect/v2/home.

  2. In the navigation pane, choose Virtual Interfaces.

  3. Select the virtual interface and then choose View details.

  4. Under Peerings, select the peering that you want to delete and then choose Delete.

  5. In the Remove peering from virtual interface dialog box, choose Delete.
