The configurations for PE 4 and CE 4 are similar to those for PE 3 and CE 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
Destination/Mask
3.3.3.9/32
4.4.4.9/32
30.1.1.0/24
30.1.1.1/32
30.1.1.2/32
127.0.0.0/8
127.0.0.1/32
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
Destinations : 11
Destination/Mask
1.1.1.9/32
2.2.2.9/32
Routes : 7
