Figure 97 Network diagram for 6PE
The P (Provider) router in the above figure refers to a backbone router in the network of a service provider.
P is not directly connected with a CE, and is required to have the basic MPLS capability.
When an ISP wants to utilize the existing IPv4/MPLS network to provide IPv6 traffic switching capability,
only the PE routers must be upgraded. Therefore, it is a highly efficient solution. Furthermore, the
operation risk of the 6PE technology is very low.
Configuration prerequisites
Before you configure 6PE, complete the following tasks:
• Configure the MPLS basic capability for the IPv4 MPLS backbone. For more information, see MPLS
Configuration Guide.
• Configure the IPv6 BGP peer on the PE devices. For more information, see "Configuring BGP."
• If a peer group is to be specified, create the peer group beforehand in BGP view.
