4.4 Configuring Basic BGP/MPLS IPv6 VPN

The basic BGP/MPLS IPv6 VPN is established only on one SP network and the MPLS backbone
network does not span multiple ASs. In addition, the role of each PE, P, or CE is unique. That
is, a router cannot function as both a PE and a CE.

4.4.1 Establishing the Configuration Task

Before configuring BGP/MPLS IPv6 VPN, familiarize yourself with the applicable
environment, complete the pre-configuration tasks, and obtain the required data. This can help
you complete the configuration task quickly and accurately.
Applicable Environment
The BGP/MPLS IPv6 VPN networking mentioned in this section involves only a carrier and an
MPLS backbone network (not inter-provider), and LSP serves as the public tunnel. The functions
of the PE, the P and the CE are simple. None of them serves as both the PE and the CE.
Certain special BGP/MPLS IPv6 VPN networking scenarios such as, inter-provider VPN and
Carrier's Carrier need additional configurations. For more information, see the related sections
in this chapter.
When configuring the BGP/MPLS IPv6 VPN, management of the advertisement of VPN routes
on the MPLS backbone networks is a key task, including the management of routes
advertisement between the PE and the CE, and between the PEs.
For the route exchange between the PE and the CE, you can configure static routes, RIPng multi-
instance, IS-ISv6 multi-instance or BGP4+ according to the networking situations. The MP-
IBGP is adopted between the PEs.
