Darren,

VRRP uses a virtual ip address that your clients use as a gateway address, but their real addresses are in the same subnet:

Router1:

ip address 192.168.1.2 255.255.255.0

vrrp 1 ip 192.168.1.1

vrrp 1 priority 101

vrrp 1 preempt delay 10

Router2:

ip address 192.168.1.3 255.255.255.0

vrrp 1 ip 192.168.1.1

vrrp 1 preempt delay 10

If Router1 were to fail, Router2 would take over the requests after a 10 second delay. All of your clients would have the 192.168.1.1 address assigned to them as their gateway.

HTH,

John
