Figure 5-140 VRRP Virtual Router Settings window
The fields that can be configured are described below:
Parameter
Description
Interface Name
Specifies the IP interface name used to create a VRRP entry.
State
Specifies the state of the virtual router function of the interface.
Preempt Mode
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.
VRID (1-255)
Specifies the ID of the Virtual Router used. 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.
Priority (1-254)
Specifies the priority to be used for the Virtual Router Master election process. 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.
Critical IP Address
Specifies an 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.
IP Address
Specifies the virtual router’s IP address used. 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.
Advertisement Interval
(1-255)
Specifies the time interval used between sending advertisement messages.
Checking Critical IP
Specifies the state of checking the status (active or inactive) of a critical IP address.
