Can i have two hsrp with different subnets?

[dolanduck.]

lets say i have 2 routers and on router 1 int g0/0 has ip add 192.168.1.1 255.255.255.0

router 2 has int g0/0 ip add 192.168.2.1 255.255.255.0

can i have hsrp on one sub-net like 192.168.1.254 and the second router second hsrp on second sub 192.168.2.254 and the first router acting as a back up  for the second router and vise versa

Hi @dolanduck. ,

To my knowledge, the participating router of the same HSRP must be in the same network.

In your case, I usually create a communication vlan between the routers and configure the protocol in the sub-interfaces of the routers, leaving them in the same network.

so what your saying is that hsrp can only back up then are on the same sub-net

Hi @dolanduck. ,

Yes, the routers that participate in the same HSRP must be in the same sub-network.

No. We cannot have like that because the HSRP was introduced to have a lan kevel redundancy only. 

Also hello mechanism of HSRP uses multicast Mac address.
