6PE configuration example
Network requirements
As shown in Figure 76, use 6PE to connect two isolated IPv6 networks over an IPv4/MPLS network.
• The ISP uses OSPF as the IGP.
• PE 1 and PE 2 are edge devices of the ISP, and establish an IPv4 IBGP connection between
them.
• CE 1 and CE 2 are edge devices of the IPv6 networks, and they connect the IPv6 networks to
the ISP.
• A CE and a PE exchange IPv6 packets through IPv6 static routing.

Configuration procedure
1. Configure IPv6 addresses and IPv4 addresses for interfaces. (Details not shown.)
2. Configure PE 1:
# Enable LDP globally, and configure the LSP generation policy.
<PE1> system-view
[PE1] mpls lsr-id 2.2.2.2
[PE1] mpls ldp
[PE1-ldp] lsp-trigger all
[PE1-ldp] quit
# Enable MPLS and LDP on VLAN-interface 30.
[PE1] interface vlan-interface 30
[PE1-Vlan-interface30] mpls enable
[PE1-Vlan-interface30] mpls ldp enable
[PE1-Vlan-interface30] quit
# Configure IBGP, enable the peer's 6PE capabilities, and redistribute IPv6 direct and static
routes.
