What are the common scenarios and use cases for deploying GLBP in a network?
Gateway Load Balancing Protocol (GLBP) is a Cisco proprietary routing protocol that provides redundancy and load balancing for multiple routers in a network. Unlike other protocols, such as Hot Standby Router Protocol (HSRP) or Virtual Router Redundancy Protocol (VRRP), GLBP allows all routers in a group to actively forward traffic, rather than having a single active router and one or more standby routers. This improves the utilization of network resources and avoids congestion. In this article, we will explore some common scenarios and use cases for deploying GLBP in a network.
