The GLBP group priority is a key factor in determining which router is elected as the Active Virtual Gateway (AVG) within a Group Load Balancing Protocol (GLBP) configuration. In GLBP, multiple routers can participate in forwarding traffic to a virtual IP address, and the AVG is the router responsible for responding to ARP requests for that address and directing traffic to the correct Active Virtual Forwarders (AVFs).

The group priority assigns a value to each router participating in the GLBP group, and routers with higher priorities have a better chance of being elected as the AVG. If there is a tie in the group priority values, the router with the highest MAC address will be chosen as the AVG. Therefore, the primary role of the GLBP group priority is to influence the election process of the AVG, ensuring load balancing and redundancy within the network.

Understanding this concept is crucial for network professionals who need to design reliable and efficient routing architectures that utilize GLBP for load balancing and failover scenarios.
