Setting the Priority for the Virtual Router

The valid range to assign a virtual router priority is 1 to 254 with 1 being the lowest priority and 254
being the highest priority. The default value is 100 for switches with secondary IP addresses and 255 for
switches with the primary IP address.
To set the priority 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 250
switch(config-if-vrrp)#
Step 4
switch(config-if-vrrp)# priority 2
switch(config-if-vrrp)# no priority
To set the priority 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)# priority 2
switch(config-if-vrrp-ipv6)# no priority

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)#
