The output shows that Switch D has learned the network 1::/64 from Switch C through route
reflection.
6PE configuration example
Network requirements
As shown in Figure 82, 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.
