Figure 1-7. CDM-625/A 1:1 IP Redundancy Router Mode – Switchover (‘B’ Online)
Per Figure 1-7, the backup modem will also broadcast a “gratuitous ARP” which will tell all local
devices to now associate a new MAC address for the Traffic IP 172.18.10.20. Each device will
update their ARP tables and traffic will resume virtually instantaneously.
