# Configure IP addresses of the interfaces on the CEs according to Figure 3-3. The configuration
procedure is not given here.
After the configuration, run the display ip vpn-instance verbose command on the PEs, and you
can see the configuration of the VPN instances. The PEs can ping the connected CEs
successfully.
NOTE
If multiple interfaces on a PE are bound to the same VPN, you must specify the source address when you
run the ping -vpn-instance command to ping the CE connected to the peer PE. That is, specify -a source-
ip-address in the ping -vpn-instance vpn-instance-name -a source-ip-address destination-address
command. Otherwise, the ping operation may fail.
Take PE1 and CE1 for example.

Step 4 Set up EBGP peer relation between the PE and the CE and import VPN routes.
# Configure CE1.
[CE1] bgp 65410
[CE1-bgp] peer 10.1.1.2 as-number 100
[CE1-bgp] import-route direct
NOTE
The configuration procedures of CE2, CE3 and CE4 are similar to the configuration procedure of CE1 and
are not mentioned here.
