After the above configurations, run the display bgp vpnv4 vpn-instance peer command. You
can find the BGP peer relationship between PE and CE is set up, that is the "State" in display is
"Established". Run display bgp vpnv4 all peer to find the BGP peer relationship is "Established"
between the PE and the CE, and between the PE and the ASBR.
Consider PE1 as an example.
