R3303-HP HSR6800 Routers Layer 3 - IP Routing Configuration Guide

• Between the PE routers is the IPv4/MPLS network of an ISP. The two PEs establish an IPv4 IBGP
connection in between, and the IGP used is OSPF.
• The CEs reside in IPv6 networks. A CE and a PE exchange IPv6 packets through a static route
• Connect the two IPv6 networks through the IPv4/MPLS network with the 6PE feature.

Configuration procedure
1. Configure CE 1:
# Enable IPv6 packet forwarding.
<CE1> system-view
[CE1] ipv6
# Specify IP addresses for interfaces.
[CE1] interface serial 2/2/0
[CE1-Serial2/2/0] ipv6 address auto link-local
[CE1-Serial2/2/0] quit
[CE1] interface loopback0
[CE1-LoopBack0] ipv6 address 1::1/128
[CE1-LoopBack0] quit
# Configure an IPv6 static route to PE 1.
[CE1] ipv6 route-static :: 0 serial2/2/0
2. Configure PE 1:
# Enable IPv6 packet forwarding, MPLS, and LDP.
<PE1> system-view
[PE1] ipv6
[PE1] mpls lsr-id 2.2.2.2
[PE1] mpls
[PE1-mpls] lsp-trigger all
[PE1-mpls] quit
[PE1] mpls ldp
[PE1-mpls-ldp] quit
# Configure an IPv6 link-local address for Serial 2/2/0.
[PE1] interface serial 2/2/0
[PE1-Serial2/2/0] ipv6 address auto link-local
