An airport authority isolates department networks across a shared county MPLS core. Which architecture provides that separation?
Select an answer to reveal the explanation.
Short Explanation
One shared core, many locked departmental drawers—that’s L3VPN. Each department gets a VRF on the PEs while P routers stay label-switchers in the middle. ACLs in one big table aren’t the same as real VPN separation.
Full Explanation
MPLS L3VPN isolates customer or departmental routing using VRFs on PE routers while P routers forward labeled traffic without holding VPN routes. That model lets an airport authority share county core infrastructure without merging department tables. A single global table with ACLs, flat bridging, or MAC-rewriting PBR on P routers does not provide equivalent scalable VPN separation.
