We have only two available IP address to be used for VRRP in basic configuration.
That is router interface physical IP becomes the virtual IP address of the VRRP group of two routers. If master fails then backup router will take the same IP address. ( but it will have different physical IP address).
Searched on cisco.com but could not find basic configuration. It says about using a third IP address as a virtual IP address or some kind of secondary IP address. Main thing is only two IP address are available and we need to configure redundancy.
Please share the experience.
Master IP = 10.10.1.1 /24
Back IP = 10.10.1.2 /24
Virtual IP of group = 10.10.1.1 ( same as that of master router ).
There is some drawback of this conf. as "tracking" can not be used to reduce the priority of Master router but that is ok, this is not mandatory condition for us.
Any link on cisco.com or any other URL is appreciated.
Thanks in advance.

If you have any further questions, let us know. Also, you're going to need two physical ip addresses and a virtual address that doesn't conflict with your physical.
Master IP = 10.10.1.2/24
Back IP = 10.10.1.3/24
Virtual = 10.10.1.1
