Interface (VLAN)
COMMAND USAGE
â—† The interfaces of all routers participating in a virtual router group must
be within the same IP subnet.
â—† If the IP address assigned to the virtual router with this command is
already configured as the primary address on this interface, this router
is considered the Owner, and will assume the role of the Master virtual
router in the group.
â—† This interface is used for two purposes - to send/receive advertisement
messages and to forward on behalf of the virtual router when operating
as the Master VRRP router.
â—† VRRP is enabled as soon as this command is entered. If you need to
customize any of the other parameters for VRRP such as
authentication, priority, or advertisement interval, then first configure
these parameters before enabling VRRP.
EXAMPLE
This example creates VRRP group 1 using the primary interface for VLAN 1
as the VRRP group Owner.
Console(config)#interface vlan 1
Console(config-if)#vrrp 1 ip 192.168.1.6
Console(config-if)#
vrrp preempt This command configures the router to take over as the master virtual
