Run the

display bgp vpnv4 vpn-instance peer

command on the ASBR PE, and you can see

that the BGP peer relation is established between the ASBR-PEs.

Step 6

Verify the configuration.

After the preceding configuration, CEs can learn the routes from the interfaces of each other,
and CE1 and CE2 can ping each other successfully.

Take the display on CE1 as an example:
