6. Configure CE 2:
# Configure an IP address for VLAN-interface 12.
<CE2> system-view
[CE2] interface vlan-interface 12
[CE2-Vlan-interface12] ip address 20.0.0.2 24
[CE2-Vlan-interface12] quit
# Configure 20.0.0.1 as an EBGP peer, and redistribute direct routes.
[CE2] bgp 65002
[CE2-bgp] peer 20.0.0.1 as-number 600
[CE2-bgp] address-family ipv4 unicast
[CE2-bgp-ipv4] peer 20.0.0.1 enable
[CE2-bgp-ipv4] import-route direct
[CE2-bgp-ipv4] quit
[CE2-bgp] quit
Verifying the configuration
# Execute the display ip routing-table command on CE 1 and CE 2 to verify that CE 1 and CE 2 can ping
each other. (Details not shown.)

Configuring MPLS L3VPN carrier's carrier

Network requirements
Configure carrier's carrier for the scenario shown in
PE 1 and PE 2 are the provider carrier's PE switches. They provide VPN services for the customer
•
carrier.
CE 1 and CE 2 are the customer carrier's switches. They are connected to the provider carrier's
•
backbone as CE switches.
PE 3 and PE 4 are the customer carrier's PE switches. They provide MPLS L3VPN services for the end
•
customers.
CE 3 and CE 4 are customers of the customer carrier.
•
The key to carrier's carrier deployment is to configure exchange of two kinds of routes:
Exchange of the customer carrier's internal routes on the provider carrier's backbone.
•
• Exchange of the end customers' VPN routes between PE 3 and PE 4, the PEs of the customer carrier.
In this process, an MP-IBGP peer relationship must be established between PE 3 and PE 4.
