Nokia`s VRRP protocol allows for an active-standby firewall cluster. Nokia have added an extension to VRRP called VRRP monitored circuit which handles both total firewall failure as well as interface failures.
Each virtual router uses a mac address of 00-00-5E-00-01-XX. XX being the Virtual Router ID (VRID).
The multicast of 184.108.40.206 and IP protocol number 112 is used by each physical router for communication.
Each router has a priority of 0-255 and the router with the highest priority is designated master.
In the event of the backup router not receiving a multicast packet from the master router for a time period of 3 times that of the advertisement timer causes the backup router to become the master router.
