Command Parameters
- <vrid> preempt-mode enable
- Enables preempt mode for vrrp
(v3).
- action {none|preempt}
- Use the action choice option to
manually override the hold-down timer and force preemption. none|preempt can be
set to preempt the timer or set to none to allow the timer to keep working.
- address <1-255> <A.B.C.D>
- Sets the IP address of the Virtual
Router Redundancy Protocol (VRRP) interface that forwards packets to the virtual
IP addresses associated with the virtual router. A.B.C.D is the IP address of the
master VRRP.
- adver-int <1-255>
- Sets the the time interval between
sending Virtual Router Redundancy Protocol (VRRP) advertisement messages. The
range is between 1 and 255 seconds. This value must be the same on all the
participating routers. The default is 1.
- backup-master enable
- Enables the Virtual Router
Redundancy Protocol (VRRP) backup master. This option is supported only on Split
MultiLink Trunking (SMLT) ports. Do not enable Backup Master if Critical IP is
enabled.
- critical-ip enable
- Enables the critical IP address
option. Do not enable critical IP if Backup Master is enabled.
- critical-ip-addr <A.B.C.D>
- Sets the critical IP address for
VRRP. A.B.C.D is the IP address on the local router, which is configured so that a
change in its state causes a role switch in the virtual router (for example, from
master to backup in case the interface goes down).
- enable
- Enables Virtual Router Redundancy
Protocol (VRRP) on the interface.
- fast-adv enable
- Enables the Fast Advertisement
Interval. The default is disabled.
- fast-adv-int <200-1000>
- Sets the Fast Advertisement
Interval, in milliseconds, the time interval between sending VRRP advertisement
messages. The range must be the same on all participating routers. The default is
200. You must enter values in multiples of 200 milliseconds.
- holddown-timer<0-21600>
- Modifies the behavior of the
Virtual Router Redundancy Protocol (VRRP) failover mechanism by allowing the
router enough time to detect the OSPF or RIP routes. 0-21600 is the time interval
(in seconds) a router is delayed when changing to master state.
- priority <1-255>
- Sets the port Virtual Router
Redundancy Protocol (VRRP) priority. 1-255 is the value used by the VRRP router.
The default is 100. Assign the value 255 to the router that owns the IP address
associated with the virtual router.
