A city data-center leaf must steer traffic from a permitting-office subnet into an inspection routing instance before it reaches tenant servers. Which Junos mechanism selects an alternate forwarding routing instance based on a packet filter match?
Select an answer to reveal the explanation.
Short Explanation
Think of FBF like a traffic cop who reads a plate and sends that car down a side ramp to inspection—not into a ditch. The filter matches the city’s subnet and hands those packets to another routing instance. Drop filters only kill traffic; FBF steers it.
Full Explanation
Filter-based forwarding uses a firewall filter match to select an alternate forwarding routing instance (commonly via a routing-instance action). That lets the leaf redirect the permitting subnet into an inspection VRF while leaving other traffic on the normal tenant path. Discard or reject terms drop packets rather than steer them, and EVPN or underlay multipath alone do not perform filter-selected instance redirection.
