Run the ping 34.1.1.1 command on CE1, and the ping is successful. Run the display
interface command to view the statistics about packets on GE 3/0/1 and GE3/0/2 of PE2, and
you can see that there are packets passing through GE 3/0/1 but there is not any packet passing
through GE3/0/2. This indicates that the two VPN instances contain same addresses but users
in the VPNs cannot communicate with each other.
