6VPE Configuration
This chapter explains how 6VPE (IPv6 on VPN Provider Edge Routers) can interconnect IPv6 islands over an MPLS- enabled IPv4 cloud. 6VPE enables IPv6 sites to communicate with each other over an MPLS/IPv4 core network using MPLS LSPs. The 6VPE routers exchange IPv6 reachability information over the core using Multi-Protocol Border Gateway Protocol (MP-BGP) over IPv4.
Topology
As shown in Figure 14:
| • | CE1 and CE2 are customer edge routers |
| • | 6VPE1 and 6VPE2 are IPv6 Provider Edge routers |
| • | P is the router at the core of the IPv4 MPLS provider network. |
