User Guidelines
The virtual router IP addresses must be a valid host address on the local
subnet based on the IP address and subnet mask configured on the VLAN
interface. The VRRP IP address cannot be either the broadcast address or a
network address. To configure vrrp, perform the following steps:
1
Enable ip routing in global configuration mode.
2 Enable ip vrrp globally.
3 Set an IP address on the desired interface where VRRP is to be configured.
4 Configure the VRRP group ID on the selected interface.
5 Set the virtual router ID and address on the selected interface.
6 Enable VRRP on the interface using the vrrp mode command.
Example
The following example configures VRRP on VLAN 15.
console#configure
console(config)#ip routing
console(config)#ip vrrp
console(config-vlan)#vlan 15
console(config-vlan)#vlan routing 15
console(config-vlan)#exit
