GLBP (Gateway Load Balancing Protocol) GLBP Overview GLBP (Gateway Load Balancing Protocol) is an another First Hop Redundancy Protocol. It is a Cisco proprietary protocol like HSRP. So ,you can only use GLBP on Cisco devices. GLBP has a key benefit that HSRP and VRRP do not have. This benefit is load-balancing. GLBP provides load balancing over multiple routers using a single Virtual IP address and multiple Virtual MAC Addresses. Each host is configured with the same Virtual IP address, and all routers in the virtual router group participate in forwarding packets. According to the assigned MAC, each one does the forwaring. GLBP(Gateway Load Balancing Protocol) supports up to 1024 virtual routers meaning GLBP groups on each physical interface of a router. And for each GLBP group, 4 virtual forwarders are supported. Main Differences Between GLBP and HSRP/VRRP In this lesson, I think it will be better to compare GLBP with HSRP and VRRP. So, you can easily understand the difference
