18.1 6PE Overview
IPv6 Provider Edge (referred to as 6PE in short) enables isolated IPv6 CE routers to
communicate with each other through IPv4 PE routers over an MPLS IPv4 backbone
network.
6PE has the following features:
l
The IPv6 protocol is implemented only on the specified PE routers.
l
The PE routers use the MP-BGP protocol to transmit IPv6 routes over the backbone
network
l The MPLS label is assigned to the IPv6 routes by the PE routers, and transparently
transmitted between the PE routers.
l
A two-layer MPLS label stack is used to transmit IPv6 packets over the MPLS IPv4
backbone network. The labels are classified into the LDP labels (in the first layer) for
the egress PE routers and the PE IPv6 labels (in the second layer)
During implementations, the MPLS-labeled IPv6 routes are advertised through MP-BGP.
