Explanation

VRF (Virtual Routing and Forwarding) creates multiple isolated routing table instances on a single router or Layer 3 switch. Its two core components are the RIB (Routing Information Base), which is the logical routing table that stores all learned routes for a given VRF instance, and the FIB (Forwarding Information Base), which is the optimized forwarding table derived from the RIB used to make actual packet-switching decisions. VSS (Virtual Switching System) is a Cisco technology for combining two physical switches into one logical switch and is unrelated to VRF. HSRP (Hot Standby Router Protocol) is a first-hop redundancy protocol and is also not a VRF component.
