Configure IPv6 on the Customer and Core-Facing Interfaces

In addition to configuring family inet6 on all the CE-facing interfaces, you must also configure family inet6 on all the core-facing interfaces running MPLS. The router must be able to process any IPv6 packets it receives on these interfaces. You should not see any regular IPv6 traffic arrive on these interfaces, but you will receive MPLS packets tagged with label 2. Even though label 2 MPLS packets are sent in IPv4, these packets are treated as native IPv6 packets.

[edit]

interfaces {

    interface-name {

        unit unit-number {

            family inet6 {

                address inet6-address;

            }

        }

    }

}
