Example for Configuring 6PE

Networking Requirements

In Figure 1, PE1 and PE2 support 6PE, and CE1 and CE2 support the IPv6 protocol. A carrier's IPv4/MPLS backbone network exists between PE1 and PE2. The IPv4/MPLS backbone network runs OSPF. IPv4 IBGP connections are set up between PEs. CE1 and CE2 are located on two IPv6 networks respectively. PEs and CEs use IPv6 addresses to exchange route information through static routes.

6PE must be configured to connect IPv6 networks through the IPv4/MPLS backbone network.

Figure 1 Networking diagram for configuring 6PE

Configuration Roadmap

The configuration roadmap is as follows:

  1. Enable IPv6 and configure an IPv4/IPv6 dual stack.

  2. Enable MPLS.

  3. Configure a 6PE peer.

  4. Configure IPv6 addresses for CE interfaces and static routes.

Procedure

  1. Enable IPv6 and configure an IPv4/IPv6 dual stack.

  5. Verify the configuration.

    # Ping the IPv6 address of CE2 from CE1.

    [CE1] ping ipv6 FC00:4::2
