Setting the time Interval for Advertisement Packets
The valid time range for an advertisement packet on an interface using IPv4 is between 1 and 255
seconds. The default value is 1 (one) second. If the switch has the primary IP address, this time must be
specified.
To set the time interval for advertisement packets for a virtual router using IPv4, follow these steps:
Command
Step 1
switch# config t
Step 2
switch(config)# interface vsan 10
switch(config-if)#
Step 3
switch(config-if)# vrrp 50
switch(config-if-vrrp)#
Step 4
switch(config-if-vrrp)# advertisement-interval 15
switch(config-if-vrrp)# no advertisement-interval
To set the time interval for advertisement packets for a virtual router using IPv6, follow these steps:
Command
Step 1
switch# config t
Step 2
switch(config)# interface vsan 12
switch(config-if)#
Step 3
switch(config-if)# vrrp ipv6 200
switch(config-if-vrrp-ipv6)#
Step 4
switch(config-if-vrrp-ipv6)#
advertisement-interval 150
switch(config-if-vrrp-ipv6)# no

Configuring or Enabling Priority Preemption
You can enable a higher priority backup virtual router to preempt the lower priority master virtual router.
Note
If the virtual IP address is also the IP address for the interface, then preemption is implicitly applied.
Note
The VRRP preemption is not supported on IP storage Gigabit Ethernet interfaces.
