In addition to configuring the family inet6 statement on all the CE router–facing interfaces, you must also configure the statement on all the core-facing interfaces running MPLS. Both configurations are necessary because 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.
Include the family inet6 statement:
- family inet6 {
- address inet6-address;
- }
You can include this statement at the following hierarchy levels:
