This section allows users to set the VRRP parameters.
Tick to enable VRRP protocol. VRRP (Virtual Router Redundancy Protocol) is
an Internet protocol that provides a way to have one or more backup routers
when using a statically configured router on a local area network (LAN).Using
VRRP, a virtual IP address can be specified manually.
Specify which VRRP group of this router belong to.
Enter the priority value from 1 to 255. The larger value has higher priority.
The interval that master router sends keepalive packets to backup routers.
A virtual IP address is shared among the routers, with one designated as the
master router and the others as backups. In case the master fails, the virtual
IP address is mapped to a backup router's IP address. (This backup becomes
the master router.)
