GLBP is similar to the High availability protocols Hot Standby Redundancy Protocol (HSRP) & Virtual Router Redundancy Protocol (VRRP) except for the load balancing capabilities wherein HSRP and VRRP, the standby routers are configured for redundancy and act as standby only and become active only when the active router fails. The advantage of GLBP is it provides load balancing over multiple routers (gateways) using a single virtual IP address and multiple virtual MACRead More →
