CISCOSB-PBR-MIB is a private Cisco Small Business MIB that manages Policy-Based Routing (PBR), letting traffic on an interface be forwarded according to route-map policy rather than plain destination-based routing. It exposes configuration data mapping interfaces to route-maps and derived operational information such as the resolved access-list and next-hop address the policy is currently using. From a monitoring perspective it is mainly about software/configuration status: confirming a PBR policy is active and enabled on the expected interface (rlPBRStatus/rlPBRRowStatus) and that it is resolving to the intended next hop, which is critical for verifying traffic-engineering or failover policies are actually being applied. It relies on the standard ifIndex convention from IF-MIB to bind policies to interfaces, and on route-map/access-list constructs shared with Cisco's routing MIBs. It is typically deployed on Cisco Small Business routers where selective path steering (e.g., for VPN or ISP failover) is configured. Network engineers evaluating or troubleshooting this functionality can download the CISCOSB-PBR-MIB file directly to load it into their MIB browser.

An administrator would check rlPBRTable/rlPBREntry keyed by rlPBRIfIndex to confirm rlPBRRouteMapName is bound and rlPBRStatus shows the policy active on the intended interface. Cross-referencing rlPBRInfoTable's rlPBRInfoAccessListName and rlPBRInfoNexthopInetAddress reveals which access-list classified the traffic and which next hop it was actually routed to, letting an admin confirm PBR is steering traffic as designed. If rlPBRInfoNexthopInetAddress unexpectedly shows the default gateway instead of the policy-specified next hop, the route-map match criteria are likely misconfigured.

Cisco Small Business policy-based routing MIB for managing and monitoring policy-based routing configurations that classify and forward traffic based on defined policies instead of destination routing.
