What is the difference between Hot Standby Router Protocol (HSRP) and Gateway Load Balancing Protocol (GLBP)?

Question

Accepted Answer

HSRP provides high availability by allowing multiple routers to work together as a single virtual router, while GLBP provides load balancing and redundancy by distributing traffic across multiple routers.

HSRP allows for a standby router to take over in case the primary router fails, while GLBP allows for multiple routers to share the traffic load.
HSRP uses a virtual IP address and a virtual MAC address, while GLBP uses multiple virtual MAC addresses.
HSRP has a single active router at a time, while GLBP can have multiple active routers sharing the load.
HSRP is Cisco proprietary, while GLBP is an open standard protocol.
HSRP has a priority value to determine the active router, while GLBP uses a weighting system to determine the router that will handle the next new connection.
