A port authority exchanges VPN routes between PE routers for civic VRFs. Which control-plane mechanisms distinguish and control those customer tables?
Select an answer to reveal the explanation.
Short Explanation
RD makes overlapping civic prefixes unique in BGP; RT decides who imports what. MP-BGP VPNv4 is the PE-to-PE control plane that carries those VPN routes. LDP still does transport labels—different job.
Full Explanation
MP-BGP VPNv4 advertises VPN routes between PEs. Route distinguishers uniquify prefixes in the BGP table, and route targets control VRF import/export policy. LDP and IGP metrics support the underlay, and P routers normally do not hold per-VRF static customer routes as the PE-PE signaling method.
