What Does FHRP Mean in 200-301?
Full form: First Hop Redundancy Protocol
Also known as: First Hop Redundancy Protocol
Quick Definition
A category of protocols that provide a virtual gateway IP shared across multiple routers for redundancy.
Full Definition
FHRP is an umbrella term for protocols that eliminate the single-point-of-failure of having one physical router as a default gateway. Members of the FHRP category include HSRP (Cisco proprietary), VRRP (open standard), and GLBP (Cisco proprietary with load balancing). All FHRPs work by advertising a virtual IP address and virtual MAC that hosts configure as their default gateway, while multiple physical routers compete to service traffic through that virtual address.
Exam Trap — Don't Get Fooled
HSRP and VRRP both use an active/standby model. GLBP is different — it provides load balancing by using multiple virtual MACs, allowing all routers to actively forward traffic simultaneously.
