Configure BGP MD5 Authentication for Tenant BGP Peer-group

You can provide an MD5 password during BGP peer-group create or update operations.

  1. Use the efa tenant service bgp peer-group create command to create the peer group. 
    efa tenant service bgp peer-group create 
           --name <bgp-pg-name> --tenant <tenant-name>
           --pg-name <device-ip:pg-name> --pg-asn <device-ip,pg-name:remote-asn>
           --pg-bfd-enable <device-ip,pg-name:true|false> 
           --pg-md5-password <device-ip,pg-name:md5-password>
  2. Use the efa tenant service bgp peer-group update command to update the peer group. 
    efa tenant service bgp peer-group update 
           --name <bgp-pg-name> --tenant <tenant-name> 
           --operation peer-group-add 
           --pg-name <device-ip:pg-name> --pg-asn <device-ip,pg-name:remote-asn>
           --pg-bfd-enable <device-ip,pg-name:true|false> 
           --pg-md5-password <device-ip,pg-name:md5-password>

    Example

    efa tenant service bgp peer-group create 
           --name ten1bgppg1 --tenant ten1 
           --pg-name 10.20.246.15:pg1 --pg-asn 10.20.246.15,pg1:55001 
           --pg-bfd-enable 10.20.246.15,pg1:true 
           --pg-md5-password 10.20.246.15,pg1:password 
           --pg-name 10.20.246.16:pg1 --pg-asn 10.20.246.16,pg1:55001 
           --pg-bfd-enable 10.20.246.16,pg1:true 
           --pg-md5-password 10.20.246.16,pg1:password

efa tenant service bgp peer-group update 
           --name ten1bgppg1 --tenant ten1 
           --operation peer-group-add 
           --pg-name 10.20.246.15:pg2 --pg-asn 10.20.246.15,pg2:55002 
           --pg-bfd-enable 10.20.246.15,pg2:true 
           --pg-md5-password 10.20.246.15,pg2:password1 
           --pg-name 10.20.246.16:pg2 --pg-asn 10.20.246.16,pg2:55002 
           --pg-bfd-enable 10.20.246.16,pg2:true 
           --pg-md5-password 10.20.246.16,pg2:password1

    Note

    Note

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