Configuring carrier’s carrier
Network requirements
Configure carrier’s carrier for the scenario shown in
. In this scenario:
•
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 connect to the provider carrier’s backbone
as CE switches.
•
PE 3 and PE 4 are the customer carrier’s PE switches. They provide IPv6 MPLS L3VPN services for
the end customers.
•
CE 3 and CE 4 are customers of the customer carrier.
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.
