Explanation:
GLBP, an acronym for Gateway Load Balancing Protocol. The key idea with GLBP is accomplishing load-balancing by responding to ARP requests with different virtual MAC addresses.
GLBP can use of up to 4 routers at same time.
In GLBP, there is one virtual IP address but each router has a different virtual MAC address.
A GLBP group must elect an Active Virtual Gateway (AVG).
The AVG is responsible for replying ARP requests from hosts/clients. It replies with different virtual MAC addresses for different routers to share the load.
