A municipal guest Wi-Fi portal must redirect unauthenticated client traffic into a captive-portal routing instance on the EVPN-VXLAN leaf. Which approach best matches a classic filter-based forwarding use case?
Select an answer to reveal the explanation.
Short Explanation
Picture the guest network as a lobby: unknowns get walked to the kiosk, not the elevators. FBF is that escort—match the guest traffic and hand it to the captive routing instance. Pure underlay defaults or DCI stretch do not build that portal detour.
Full Explanation
Classic FBF use cases include guest captive portals, scrubbing, and IDS steering: a filter selects traffic and forwards it into a dedicated routing instance. That policy-based redirection is independent of simply advertising underlay defaults or stretching VLANs over DCI. GBP microsegmentation complements isolation but does not by itself implement captive-instance redirection the way FBF does.
