Configuring VRRP
1073
This example configures two VRRP groups on each router. Router A is the
VRRP master for the VRRP group with VRID 10 and the backup for VRID 20.
Router B is the VRRP master for VRID 20 and the backup for VRID 10. If
Router A fails, Router B will become the master of VRID 10 and will use the
virtual IP address 192.168.10.1. Traffic from the clients configured to use
Router A as the default gateway will be handled by Router B.
To configure Router A:
1
Enable routing for the switch.
console#
config
console(config)# ip routing
2
Create and configure the VLAN routing interface to use as the default
gateway for network clients. This example assumes all other routing
interfaces, such as the interface to the external network, have been
configured.
console(config)# interface vlan 10
console(config-if-vlan10)# ip address 192.168.10.1 255.255.255.0
console(config-if-vlan10)#
exit
3
Enable VRRP for the switch.
console(config)#
ip vrrp
4
Assign a virtual router ID to the VLAN routing interface for the first VRRP
group.
console(config)#
interface vlan 10
console(config-if-vlan10)# vrrp 10
5
Specify the IP address that the virtual router function will use. The router
is the virtual IP address owner (the routing interface has the same IP
address as the virtual IP address for the VRRP group), so the priority value
is 255.
console(config-if-vlan10)# vrrp 10 ip 192.168.10.1
6
Configure an optional description to help identify the VRRP group.
console(config-if-vlan10)# vrrp 10 description master
7
Assign a virtual router ID to the VLAN routing interface for the second
VRRP group.
console(config-if-vlan10)# vrrp 20
8
Specify the IP address that the virtual router function will use.
console(config-if-vlan10)# vrrp 20 ip 192.168.10.2
