After the configuration, run the display bgp peer or display bgp vpnv4 all peer command, and
you can see that the BGP peer relation between the PEs is in Established state.
[PE1] display bgp peer
BGP local router ID : 1.1.1.9
Local AS number : 100
Total number of peers : 1 Peers in established state : 1

Peer of vpn instance:
vpn instance vpna :
10.1.1.1 4 65410 25 25 0 00:17:57 Established 1
vpn instance vpnb :
10.2.1.1 4 65420 21 22 0 00:17:10 Established 1
Step 6 Verify the configuration.
Run the display ip routing-table vpn-instance command on the PE, and you can view the routes
to the remote CE.
Take PE1 for example.
[PE1] display ip routing-table vpn-instance vpna

The CEs in the same VPN can ping each other, but the CEs in different VPNs cannot ping each
other.
For example, CE1 can ping CE3 (10.3.1.1) but cannot ping CE4 (10.4.1.1).
[CE1] ping 10.3.1.1
PING 10.3.1.1: 56 data bytes, press CTRL_C to break
