Hi,

To use VRRP or HSRP between your 2 routers, you need to use the switch. You can create a sub-interface with dot1.q on each router and then create the same vlan id on the switch.  example:

create sub-interface 10 with dot1q of 10 on router-1 and give it an ip address.  Configure VRRP or HSRP and give it a virtual IP address.  Do the same thing on router-2 with a different IP in the same subnet and the same virtual ip.

Create vlan 10 on your switch and add it to the links that connects to both routers. Make sure the the links to both switches are configured as trunk.

Also,gave one of the routers a higher priority so it becomes the VRRP or HSRP master.  The other router will be on stand-by. Use ping to test.

router-1 192.168.1.1/24

router-2 192.168.1.2/24

vip 192.168.1.3/24
