Click the Delete button to remove a specific entry listed.
Click the Edit button to re-configure a specific entry listed.
After clicking the Edit button, the following page will be displayed.
Specifies the state of the virtual router function of the interface.
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 Master's 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.
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.
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.
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.
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.
Specifies the time interval used between sending advertisement messages.
Specifies the state of checking the status (active or inactive) of a critical IP address.
Options to choose from are Enabled and Disabled.
Enter the IP address of the Bidirectional Forwarding Detecton (BFD) peer here. This
IP address should be a real IP address of a VRRP router in the same VRRP group.
A BFD session will be created between the local VRRP virtual router and the peer.
If the local VRRP virtual router is in the Backup state and the BFD peer address is
the Master router, it will try to switch to Master fast when the BFD session goes
down. Using the IP address 0.0.0.0 will disable the BFD on this VRRP virtual router.
