H3C Technologies H3C S6800 Series Switches - Manual (Page 248)

• 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.
