Interprovider and Carrier-of-Carriers VPNs
Configuration Guidelines

To configure interprovider or carrier-of-carriers virtual private network (VPN) functionality, you typically need to include the labeled-unicast statement in the configuration for the Border Gateway Protocol (BGP) on the autonomous system (AS) border routers of an interprovider VPN or the provider edge (PE) and customer edge (CE) routers of a carrier-of-carriers VPN. You must also configure the provider (P) routers in the service provider's and service customer's networks.

To configure interprovider or carrier-of-carriers VPN functionality, you include statements at the [edit protocols bgp] hierarchy level:

[edit]

protocols {

    bgp {

        group group-name {

            type internal;

            local-address address;

            family inet {

                labeled-unicast;

            }

            neighbor address;

        }
