Explanation:
The Gateway Load Balancing Protocol feature provides automatic router backup for IP hosts
configured with a single default gateway on an IEEE 802.3 LAN. GLBP members
communicate between each other through hello messages sent every 3 seconds to the
multicast address 224.0.0.102, User Datagram Protocol (UDP) port 3222 (source and
destination).
