Network Design - Load Balancing vs Load Sharing

Static ARP entry for own IP address


Gateway Load Balancing Protocol (GLBP) is an [First Hop Redundancy Protocol](/fhrp-protocols) used for creating gateway redundancy in a subnet.  It is similar in functionality to [Hot Standby Router Protocol (HSRP)](/hot-standby-router-protocol-hsrp) and [Virtual Router Redundancy Protocol (VRRP)](/virtual-router-redundancy-protocol-vrrp).   

It is used to create a virtual gateway that can be used by hosts in a particular subnet.

One of the key differences of GLBP is that it can natively do load balancing between configured gateways without the group configuration that HSRP/VRRP use.
