After completing the above configuration, if you issue the display bgp peer command or the display
bgp vpnv4 all peer
command on the PEs, you should see that BGP peer relationship has been
established between the PEs, and has reached the state of Established.
[PE1] display bgp peer

Issuing the display ip routing-table vpn-instance command on the PEs, you should see the routes
to the CEs. The following takes PE 1 as an example:
[PE1] display ip routing-table vpn-instance vpn1
Routing Tables: vpn1
Destinations : 3 Routes : 3
Destination/Mask Proto Pre Cost NextHop Interface
10.1.1.0/24 Direct 0 0 10.1.1.2 Vlan11
10.1.1.2/32 Direct 0 0 127.0.0.1 InLoop0
10.3.1.0/24 BGP 255 0 3.3.3.9 NULL0
[PE1] display ip routing-table vpn-instance vpn2
Routing Tables: vpn2
Destinations : 3 Routes : 3
Destination/Mask Proto Pre Cost NextHop Interface
10.2.1.0/24 Direct 0 0 10.2.1.2 Vlan12
10.2.1.2/32 Direct 0 0 127.0.0.1 InLoop0
10.4.1.0/24 BGP 255 0 3.3.3.9 NULL0
CEs of the same VPN should be capable of pinging each other, whereas those of different VPNs
should not. For example, CE 1 should be capable of pinging CE 3 (10.3.1.1), but should not be
capable of pinging CE 4 (10.4.1.1):
[CE1] ping 10.3.1.1
