When you configure carrier-of-carriers VPNs, you need to configure the family mpls statement in addition to the family inet statement for the interfaces between the PE and CE routers. For carrier-of-carriers VPNs, configure the logical interface as follows:
- [edit interfaces]
-
interface-name {
-
- unit logical-unit-number {
- family inet;
- family mpls;
- }
- }
If you configure family mpls on the logical interface and then configure this interface for a non-carrier-of-carriers routing instance, the family mpls statement is automatically removed from the configuration for the logical interface, since it is not needed.
