34.8 Device HA Technical Reference

Legacy Mode ZyWALL VRRP Application

In VRRP, a virtual router represents a number of ZyWALLs associated with one IP address, the IP address of the default gateway. Each virtual router is identified by a unique 8-bit identification number called a Virtual Router ID (VR ID). In the example below, ZyWALL A and ZyWALL B are part of virtual router 10 with IP address 192.168.10.254.
