Configuration Guide - VPN
Step 6 Verify the configuration.
Running the display ip routing-table vpn-instance command on the PE, you can find the route
to peer CEs.
Use PE1 as an example.
[PE1] display ip routing-table vpn-instance vpna
Route Flags: R - relay, D - download to fib
------------------------------------------------------------------------------
Routing Tables: vpna
Destination/Mask
[PE1] display ip routing-table vpn-instance vpnb
Route Flags: R - relay, D - download to fib
------------------------------------------------------------------------------
Routing Tables: vpnb
Destination/Mask
The CEs in the same VPN can successfully ping each other whereas two CEs in different VPNs
cannot ping each other.
For example, CE1 can successfully ping CE3 (10.3.1.1/24) but cannot ping CE4 (10.4.1.1/24).
[CE1] ping 10.3.1.1
PING 10.3.1.1: 56
--- 10.3.1.1 ping statistics ---
[CE1] ping 10.4.1.1
PING 10.4.1.1: 56
--- 10.4.1.1 ping statistics ---
