[PE3-bgp] ipv4-family vpnv4
[PE3-bgp-af-vpnv4] peer 6.6.6.9 enable
[PE3-bgp-af-vpnv4] quit

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
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
5.5.5.9/32
6.6.6.9/32
10.1.1.0/24
