{ Configure the VPN instance of VPN 1 on PE 1 to allow CE 1 to access the network.
{ Configure BGP between PE 1 and CE 1, and between PE 2 and CE 2, and redistribute routes of
CEs into PEs.
After completing the configurations, execute the display ip routing-table command on CE 2. The
output shows that CE 2 has learned the route to network 10.1.1.0/24, where the interface used
by CE 1 to access PE 1 resides, but it has not learned the route to the VPN (100.1.1.0/24) behind
CE 1. The situation on CE 1 is similar.

# Execute the display ip routing-table vpn-instance command on the PEs. You can see the route to
the VPN behind the peer CE. Take PE 2 as an example:
