After the configuration, run the display bgp peer command on a PE, and you can see that the
BGP peer relation between the PE and CE is in Established state.
[PE1]display bgp peer
BGP local router ID : 1.1.1.9
Local ASN : 100
Total number of peers : 1 Peers in established state : 1
Peer V AS MsgRcvd MsgSent OutQ Up/Down State PrefRcv
3.3.3.9 4 100 3 3 0 00:01:08 Established

Step 7 Verify the configuration.
Run the display ip routing-table vpn-instance command on a PE, and you can view the routes
to the remote CE.
Take the display on PE1 as an example.
[PE1] display ip routing-table vpn-instance vpna
