CRS-170A L-Band 1:1 Redundancy Switch
Introduction
Whichever modem is online will assume the Traffic IP. When there is a switchover to the backup
modem, this modem will now assume the Traffic IP.
Per Figure 1-9, 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.
