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.

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
Route Flags: R - relay, D - download to fib

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
