Refer to the exhibit. A NOC engineer is configuring label-based forwarding from CSR to the EPC gateway. Cell-site operation and maintenance for IPv4 traffic between 10.20.10.1 and 192.168.10.10 is…

Removing the 'address-family labeled-unicast' from a BGP session group would disable the exchange of labels, which is contrary to configuring label-based forwarding.

For label-based forwarding (MPLS) to an EPC gateway, BGP is used to exchange routes and labels. Applying a BGP egress filter route policy to the appropriate neighbor-group, such as 'packet core' on AG1, is a common and necessary step to control which routes (and their associated labels) are advertised out of AG1, thereby completing the policy enforcement for the forwarding path.

A router typically allocates labels for prefixes it advertises to its neighbors, not necessarily for routes it receives in a BGP session group, making this statement potentially incorrect or at least not the primary completing action for outbound label allocation.

Configuring AG1 to allow specific communities in the BGP_Egress_Filter route implies modifying the filter's definition, not the act of applying an already defined filter, which is what 'completes the configuration' usually suggests.
