Description: The Gateway Load Balancing Protocol (GLBP) is a routing protocol that allows efficient distribution of network traffic across multiple gateways in a network environment. Unlike other redundancy protocols, such as HSRP (Hot Standby Router Protocol) and VRRP (Virtual Router Redundancy Protocol), GLBP not only provides redundancy but also enables active load balancing among available gateways. This means that instead of having a single gateway handle all traffic while others remain inactive, GLBP distributes client requests among multiple gateways, optimizing resource usage and improving network efficiency. GLBP employs an algorithm that assigns virtual addresses to each gateway, allowing end devices to send traffic to the least busy gateway. This approach enhances network availability and reduces the likelihood of congestion at a single point, which is crucial in high-demand environments. In summary, GLBP is a robust solution for traffic management in networks requiring high availability and performance, effectively integrating with standard routing protocols to maximize routing efficiency.
