Figure 6-92 VRRPv3 Settings (Edit, IPv4) Window
Description
Enter the virtual IPv4 address here. All routers in the same VRRP group must
be configured with the same virtual router ID and virtual address. The IPv4
address of the virtual router can be a real address configured on the routers or
an unused address. If the virtual address is equal to the real address of the
interface, this virtual router is the IPv4 address owner.
Enter the time interval value between successive advertisements by the master
router here. The range is from 100 to 4095 centi-seconds. The master will
constantly send VRRP advertisements. All virtual routers in a VRRP group
must use the same timer values.
Select to enable or disable the preemption feature here. This is used to allow a
router to take over the master role if it has a better priority than the current
master.
Enter the priority value of the virtual router here. The range is from 1 to 254.
The master of a VRRP group is elected based on the priority. The virtual router
with the highest priority becomes the master and others with lower priorities act
as the backup for the VRRP group. If there are multiple routers with the same
highest priority value, the router with the larger IPv4 address will become the
Master. The router that is the IPv4 address owner of the VRRP group is always
the master of the VRRP group and has the highest priority of 255.
Enter the critical IPv4 address here. If the critical IPv4 is configured on one
virtual router, the virtual router cannot be activated when the critical IPv4
address is unreachable. One VRRP group can only track one critical IPv4
address.
Select to enable or disable the non-owner ping feature here. This is used to
enable a non-IPv4 address owner virtual router in the master state to respond
to ICMP echo requests for IPv4 addresses.
Select to enable or disable the shutdown feature here. Avoid the common
mistake of shutting down the IPv4 address owner routers before shutting down
other non-owner routers.
