Configuring 6PE
IPv6 provider edge (6PE) is a transition technology that uses MPLS to connect sparsely populated IPv6
networks through an existing IPv4 backbone network. It is an efficient solution for ISP IPv4/MPLS
networks to provide IPv6 traffic switching capability.
Figure 61 Network diagram for 6PE
6PE mainly performs the following operations:
• 6PE assigns a label to IPv6 routing information received from a CE router, and sends the labeled
IPv6 routing information to the peer 6PE device through an MP-BGP session. The peer 6PE device
then forwards the IPv6 routing information to the attached customer site.
• 6PE provides tunnels over the IPv4 backbone so the IPv4 backbone can forward packets for IPv6
networks. The tunnels can be GRE tunnels, MPLS LSPs, or MPLS TE tunnels.
• Upon receiving an IPv6 packet, 6PE adds an inner tag (corresponding to the IPv6 packet) and then
an outer tag (corresponding to the public network tunnel) to the IPv6 packet. Devices in the IPv4
backbone network forwards the packet based on the outer tag. When the peer 6PE device receives
the packet, it removes the outer and inner tags and forwards the original IPv6 packet to the attached
customer site.
To implement exchange of IPv6 routing information, you can configure IPv6 static routing, an IPv6 IGP
protocol, or IPv6 BGP between CE and 6PE devices.
For more information about MPLS, MPLS TE, CE, and P (Provider), see MPLS Configuration Guide. For
more information about GRE, see Layer 3

Configuring basic 6PE
Before you configure 6PE, complete the following tasks:
• Establish tunnels in the IPv4 backbone network (see Layer 3—IP Services Configuration Guide).
