Huawei AR1200 Series Configuration Guide

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
Destinations : 3 Routes : 3
Destination/Mask Proto Pre Cost Flags NextHop Interface
10.1.1.0/24 Direct 0 0 D 10.1.1.2 Ethernet1/0/0
10.1.1.2/32 Direct 0 0 D 127.0.0.1 InLoopBack0
10.3.1.0/24 IBGP 255 0 RD 3.3.3.9 Ethernet2/0/1
[PE1] display ip routing-table vpn-instance vpnb
Route Flags: R - relay, D - download to fib
------------------------------------------------------------------------------
Routing Tables: vpnb
Destinations : 3 Routes : 3
Destination/Mask Proto Pre Cost Flags NextHop Interface
10.2.1.0/24 Direct 0 0 D 10.2.1.2 Ethernet2/0/0
10.2.1.2/32 Direct 0 0 D 127.0.0.1 InLoopBack0
10.4.1.0/24 IBGP 255 0 RD 3.3.3.9 Ethernet2/0/1
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).
