A township wants selected agency traffic forced out a specific DCI path rather than the default tenant exit. How can filter-based forwarding support that traffic-engineering goal?
Select an answer to reveal the explanation.
Short Explanation
FBF is a policy on-ramp: match the agency flows and hand them a routing instance whose next hop is the DCI exit you want. Throwing away Type-5 routes or discarding traffic is not engineering—it is breaking reachability.
Full Explanation
FBF can select an alternate forwarding instance or next-hop context for matched traffic, enabling path control such as forcing designated agency flows onto a preferred DCI exit. That is distinct from withdrawing EVPN routes or discarding packets. Architecture shifts like CRB alone do not implement per-flow DCI steering the way an FBF match-and-redirect does.
