Configure remove-private-as on BGP Peer

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

By default, remove-private-as is disabled.

About this task

Follow this procedure to configure a remove private as.

Procedure

  1. Run the following command to create remove private as when you 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 <switch-ip,vrf-name:ipv4-neighbor,bfd-enable(t/f),bfd-interval,bfd-rx,bfdmult> 
     --ipv4-uc-nbr-remove-private-as <device-ip,vrf-name:neighbor-ip,true|false>
  2. Run the following command to create remove private as when you 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
