The configurations for PE 4 are similar to those for PE 3. The detailed configuration steps are omitted.
6) Verify your configurations
After completing all the above configurations, you can issue the display ip routing-table command on
PE 1 and PE 2. You should see that only routes of the Level 1 carrier network are present in the public
network routing table of PE 1 and PE 2. Takes PE 1 as an example:
[PE1] display ip routing-table
Routing Tables: Public
Destinations : 7 Routes : 7
Destination/Mask Proto Pre Cost NextHop Interface
3.3.3.9/32 Direct 0 0 127.0.0.1 InLoop0
4.4.4.9/32 ISIS 15 10 30.1.1.2 Vlan12
30.1.1.0/24 Direct 0 0 30.1.1.1 Vlan12
30.1.1.1/32 Direct 0 0 127.0.0.1 InLoop0
30.1.1.2/32 Direct 0 0 30.1.1.2 Vlan12
127.0.0.0/8 Direct 0 0 127.0.0.1 InLoop0
127.0.0.1/32 Direct 0 0 127.0.0.1 InLoop0
Issuing the display ip routing-table vpn-instance command on PE 1 and PE 2, you should see that
the internal routes of the Level 2 carrier network are present in the VPN routing tables, but the VPN
routes that the Level 2 carrier maintains are not. Takes PE 1 as an example:
[PE1] display ip routing-table vpn-instance vpn1
Routing Tables: vpn1
