After completing the configuration, issue the display bgp peer command or the display bgp vpnv4 all
peer command on the PEs. The output shows that BGP peer relationship has been established between
the PEs, and has reached the Established state.

Issue the display ip routing-table vpn-instance command on the PEs. The output shows the routes to the
CEs. Take PE 1 as an example:
[PE1] display ip routing-table vpn-instance vpn1

CEs of the same VPN can ping each other, whereas those of different VPNs can not. For example, CE 1
can ping CE 3 (10.3.1.1) but cannot ping CE 4 (10.4.1.1):
[CE1] ping 10.3.1.1
