Configure BGP MD5 Authentication for Tenant BGP Peer

About this task

Provide md5-password during BGP peer create or update operations.

Procedure

  1. Run the efa tenant service bgp peer create command to create the peer. 
    efa tenant service bgp peer create 
           --name <bgp-peer-name> --tenant <tenant-name> 
           --ipv4-uc-nbr <device-ip,vrf-name:neighbor-ip,remote-asn> 
           --ipv4-uc-nbr-bfd <device-ip,vrf-name:neighbor-ip,true|false> 
           --ipv4-uc-nbr-md5-password <device-ip,vrf-name:neighborip,
ipv4-md5-password>
  2. Run the efa tenant service bgp peer update command to update the peer. 
    efa tenant service bgp peer update 
           --name <bgp-peer-name> --tenant <tenant-name> 
           --operation peer-add
           --ipv4-uc-nbr <device-ip,vrf-name:neighbor-ip,remote-asn> 
           --ipv4-uc-nbr-bfd <device-ip,vrf-name:neighbor-ip,true|false> 
           --ipv4-uc-nbr-md5-password <device-ip,vrf-name:neighborip,
ipv4-md5-password>

    Note

    Note

    The MD5 password cannot be set or unset on an existing BGP peer present within a peer instance. You need to remove the BGP peer from the BGP peer instance and then add back the BGP peer to the peer instance with the desired MD5 password configuration.
