On a Hot Standby Network, Which Packets Are Used by Upstream and Downstream Layer-2 Devices to Learn the Port for the Virtual MAC Addresses?
Solution
The active firewall periodically sends VRRP advertisement messages. The source MAC address of these packets is the virtual MAC address of the VRRP group. The upstream and downstream Layer-2 devices learn the port mapped to the virtual MAC address through the VRRP advertisement messages.
