Which command correctly applies a route-map to incoming traffic on an interface?
- set ip policy PBR_MAP
- ip policy route-map PBR_MAP
- ip route-map PBR_MAP
- route-map PBR_MAP in
Explanation: According to the sources, Policy-Based Routing (PBR) provides a flexible mechanism to implement user-defined policies that override traditional destination-based routing. To apply a route-map to incoming traffic on a specific interface, an administrator must use the ip policy route-map command in interface configuration mode. This ensures that packets entering the interface are matched against the criteria defined in the route-map before standard routing lookups are performed. This is distinct from the ip local policy command, which is used for packets locally generated by the router itself.
