6PE over MPLS
IPv6 Provider Edge Router (6PE) over Multi-Protocol Label Switching (MPLS) enables propagation of
IPv6 routes across an IPv4-based MPLS network by connecting the 6PE routers with the existing
IPv4-based MPLS infrastructure, as described in RFC 4798. The 6PE router can be an existing
Provider Edge (PE) router or a new PE router dedicated to IPv6 traffic. The 6PE routers run dual
stack IPv4 and IPv6. The 6PE router utilizes the existing MPLS cloud to forward IPv6 traffic from the
Customer Edge (CE) routers, based on the labels assigned for each IPv6 packet received from the
CE routers.
6PE over MPLS architecture
Figure 92 outlines the 6PE over MPLS architecture. The CE1 to CE6 routers are either IPv4 or IPv6.
The 6PE1 to 6PE4 routers run dual stack IPv4 and IPv6. The CE router provides connectivity with a
customer's network and a 6PE router. The CE router advertises IPv6 reachability information from
the customer's network using IPv6 static routes, Routing Information Protocol - next generation
(RIPng), Intermediate System to Intermediate System routing protocol support for IPv6 (IS-ISv6), or
Open Shortest Path First version 3 (OSPFv3) routing protocol. The 6PE router provides connectivity
with the CE router and with the MPLS domain. The 6PE router communicates with other 6PE
routers using Multi-protocol Border Gateway Protocol (MP-BGP). The outbound packets from a
customer's network are forwarded from the CE router to the 6PE router, and the inbound packets
are forwarded from the 6PE router to the CE router attached to the customer's network.
