•
PE 3 and PE 4 are the customer carrier's PE routers. They provide IPv6 MPLS L3VPN services
to end customers.
•
CE 3 and CE 4 are customers of the customer carrier.
•
The customer carrier and the provider carrier reside in the same AS.
The key to the 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' internal 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.

Configuration procedure
1. Configure MPLS L3VPN on the provider carrier backbone. Start IS-IS as the IGP, enable LDP
on PE 1 and PE 2, and establish an MP-IBGP peer relationship between the PEs:
