Configure remove-private-as on BGP Peer

To enable external connectivity, you can configure the remove-private-as attribute when you create or update BGP peer.

By default, remove-private-as is disabled and it is an IPv4 attribute only.

Procedure

  1. Run the following command to create a BGP Peer on a tenant VRF:
    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-remove-private-as <device-ip,vrf-name:neighbor-ip,true|false>
  2. Run the following command to update a BGP Peer on a tenant VRF:
    efa tenant service bgp peer update --name <bgp-peer-name> --tenant <tenant-name>
     
                 --operation peer-add
                 --ipv4-uc-nbr 10.20.246.25,v1:10.20.30.50,50000 
    		--ipv4-uc-nbr-bfd 10.20.246.25,v1:10.20.30.50,true 
    		--ipv4-uc-nbr-remove-private-as 10.20.246.25,v1:10.20.30.50,true 
    		--ipv4-uc-nbr 10.20.246.26,v1:10.20.30.50,50000 
    		--ipv4-uc-nbr-bfd 10.20.246.26,v1:10.20.30.50,true 
    		--ipv4-uc-nbr-remove-private-as 10.20.246.26,v1:10.20.30.50,false 
    
    Example:
    efa tenant service bgp peer create --name ten1bgppeer1 --tenant tenant11 
    		--ipv4-uc-nbr 10.20.246.25,v1:10.20.30.40,50000 
    		--ipv4-uc-nbr-bfd 10.20.246.25,v1:10.20.30.40,true 
    		--ipv4-uc-nbr-remove-private-as 10.20.246.25,v1:10.20.30.40,true 
    		--ipv4-uc-nbr 10.20.246.26,v1:10.20.30.40,50000 
    		--ipv4-uc-nbr-bfd 10.20.246.26,v1:10.20.30.40,true 
    		--ipv4-uc-nbr-remove-private-as 10.20.246.26,v1:10.20.30.40,true
