(QCT) (Config)#ip vrrp
4. Assign a virtual router ID to the VLAN routing interface for the first VRRP group.
(QCT) (Config)#interface vlan 10
(QCT) (if-vlan10)#ip 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.
(QCT) (if-vlan10)#ip vrrp 10 ip 192.168.10.1
6. Assign a virtual router ID to the VLAN routing interface for the second VRRP group.
(QCT) (if-vlan10)#ip vrrp 20
7. Specify the IP address that the virtual router function will use.
(QCT) (if-vlan10)#ip vrrp 20 ip 192.168.10.2
8. Enable the VRRP groups on the interface.
(QCT) (if-vlan10)#ip vrrp 10 mode
(QCT) (if-vlan10)#ip vrrp 20 mode
(QCT) (if-vlan10)#exit
(QCT) (Config)#exit
The only difference between the Router A and Router B configurations is the IP address assigned to VLAN 10.
On Router B, the IP address of VLAN 10 is 192.168.10.2. Because this is also the virtual IP address of VRID
20, Router B is the interface owner and VRRP master of VRRP group 20.
To configure Router B:
1. Enable routing for the switch.
(QCT) #config
(QCT) (Config)#ip routing
(QCT) (Config)#exit
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.
(QCT) (Config)#interface vlan 10
(QCT) (if-vlan10)#ip address 192.168.10.2 255.255.255.0
(QCT) (if-vlan10)#exit
3. Enable VRRP for the switch.
(QCT) (Config)#ip vrrp
4. Assign a virtual router ID to the VLAN routing interface for the first VRRP group.
