Description
The name of a previously configured IP interface used to create a VRRP entry is displayed.
This IP interface must have been assigned to a VLAN on the Switch.
The value displayed between 1 and 255 to uniquely identify this VRRP group on the Switch.
All routers participating in this group must have been assigned the same VRID value. This
value MUST be different from other VRRP groups set on the Switch.
Enter the IP address that will be assigned to the VRRP router. This IP address is also the
default gateway that will be statically assigned to end hosts and must be set for all routers
that participate in this group.
Used to enable and disable the VRRP IP interface on the Switch.
Enter a value between 1 and 254 to indicate the router priority. The VRRP Priority value may
determine if a higher priority VRRP router overrides a lower priority VRRP router. A higher
priority will increase the probability that this router will become the Master router of the
group. A lower priority will increase the probability that this router will become the backup
router. VRRP routers that are assigned the same priority value will elect the highest physical
IP address as the Master router. The default value is 100. (The value of 255 is reserved for
the router that owns the IP address associated with the virtual router and is therefore set
automatically.)
Enter a time interval value, in seconds, for sending VRRP message packets. This value
must be consistent with all participating routers. The default is 1 second.
This entry will determine the behavior of backup routers within the VRRP group by
controlling whether a higher priority backup router will preempt a lower priority Master router.
A True entry, along with having the backup router's priority set higher than the masters
priority, will set the backup router as the Master router. A False entry will disable the backup
router from becoming the Master router. This setting must be consistent with all routers
participating within the same VRRP group. The default setting is True.
Enter the IP address of the physical device that will provide the most direct route to the
Internet or other critical network connections from this virtual router. This must be a real IP
address of a real device on the network. If the connection from the virtual router to this IP
address fails, the virtual router will automatically disabled. A new Master will be elected from
the backup routers participating in the VRRP group. Different critical IP addresses may be
assigned to different routers participating in the VRRP group, and can therefore define
multiple routes to the Internet or other critical network connections.
Use the pull-down menu to enable or disable the Critical IP address entered above.
