To view the settings for a particular VRRP setting, click the corresponding
entry, which will display the following:
Description
Enter the name of a previously configured IP interface for which to create a VRRP
entry. This IP interface must be assigned to a VLAN on the Switch.
Enter a value between 1 and 255 to uniquely identify this VRRP group on the Switch.
All routers participating in this group must be 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 (Up) and disable (Down) 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.
