Step 7 Verify the configuration.
Run the display ip routing-table vpn-instance command on a PE, and you can view the routes
to the remote CE.
Take the display on PE1 as an example:
[PE1] display ip routing-table vpn-instance vpna
Route Flags: R - relied, 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 Vlanif10
10.1.1.2/32 Direct 0 0 D 127.0.0.1 InLoopBack0
10.1.1.255/32 Direct 0 0 D 127.0.0.1 InLoopBack0
10.3.1.0/24 BGP 255 0 RD 3.3.3.9 Vlanif30
[PE1] display ip routing-table vpn-instance vpnb
Route Flags: R - relied, 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 Vlanif20
10.2.1.2/32 Direct 0 0 D 127.0.0.1 InLoopBack0
10.2.1.255/32 Direct 0 0 D 127.0.0.1 InLoopBack0
10.4.1.0/24 BGP 255 0 RD 3.3.3.9 Vlanif30
The CEs in the same VPN can ping each other, but the CEs in different VPNs cannot ping each
other.
For example, CE1 can ping CE3 (10.3.1.1) but cannot ping CE4 (10.4.1.1).
