About This Chapter
This chapter describes the BGP/MPLS IPv6 VPN configuration, including the comparison
between the IPv6 VPN and IPv4 VPN, common networking of the BGP/MPLS IPv6 VPN, and
configurations to ensure the reliability of the BGP/MPLS IPv6 VPN.
4.1 Introduction to BGP/MPLS IPv6 VPN
This part describes the similarities and differences between BGP/MPLS IPv6 VPN and BGP/
MPLS IP VPN.
4.2 BGP/MPLS IPv6 VPN Features Supported by the S7700
This part describes the basic networking, typical networking, and reliability of BGP/MPLS IP
VPN supported by the S7700.
4.3 Configuring an IPv6 VPN Instances
The VPN instance is used to isolate VPN routes from public network routes.
4.4 Configuring Basic BGP/MPLS IPv6 VPN
The basic BGP/MPLS IPv6 VPN is established only on one SP network and the MPLS backbone
network does not span multiple ASs. In addition, the role of each PE, P, or CE is unique. That
is, a router cannot function as both a PE and a CE.
4.5 Configuring Hub and Spoke
In the networking of Hub and Spoke, an access control device is specified in the IPv6 VPN, and
users communicate with each other through the access control device.
4.6 Configuring a Tunnel Policy applied to BGP/MPLS IPv6 VPN
By default, the system selects an LSP for a BGP/MPLS IPv6 VPN and no load balancing is
carried out. If load balancing or other types of tunnels are required, you need to configure a
tunnel policy for the backbone network of the IPv6 VPN.
4.7 Configuring Inter-AS IPv6 VPN-Option A
In inter-AS IPv6 VPN OptionA, an ASBR takes the peer ASBR as its CE and advertises VPNv6
routes to the peer ASBR through EBGP+.
4.8 Configuring Inter-AS IPv6 VPN-Option B
In inter-AS IPv6 VPN OptionB, ASBRs exchange VPNv6 routes that are sent from the PEs in
the attached ASs through MP-EBGP.
