# Configure ASBR2. Create a VPN instance and bind it to the interface connected to ASBR1.
(ASBR2 regards ASBR1 as its CE after configuration.)

# Configure ASBR2 to set up the EBGP peer relationship with ASBR1.
[ASBR2] bgp 200
[ASBR2-bgp] ipv4-family vpn-instance vpn1
[ASBR2-bgp-vpn1] peer 192.1.1.1 as-number 100
[ASBR2-bgp-vpn1] import-route direct
[ASBR2-bgp-vpn1] quit
[ASBR2-bgp] quit
After the above configuration, run the display bgp vpnv4 vpn-instance peer command on
ASBRs, and you can see that the BGP peer relationship is established between the ASBRs.
Step 5 Verify the configuration.
After the above configuration, the CEs learn interface routes of each other. CE1 and CE2 can
ping through each other.
Consider CE1 as an example.
