Configuring Interfaces for Carrier-of-Carriers VPNs

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.
