I have personally used for routers in one group, the maximum I can't say, but if you would want to go beyond this I don't know.
Multiple groups are used for multple gateways, ie. the router hosts multiple networks and or course share co-host these networks with other router, for example you could have 2 layer 3 switches and each switch supported 15 vlans, then you would use 15 groups, one group for vlans.
The maximum number of hsrp groups is usually 15, typically you would use one per network but you can acttually have more than one network per group
carl how many routers for fail over its upto your requirement i dont know the exact number...
but when ever you are talking about the multiple group of hsrp then you will have the load balancing fundamental....how ...look at the following explenation...
lets say you are having router A and router B in for HSRP...now you have created two group lets say group 1 and group 3....now you can configure both the group on router A and router B such that ...router A will become active router for the group 1 and router B will become a standby for the same group
on the other heand you will have configuration such that the router B will become a active router for the group 3 and router 1 will become a standby router for the group 3
so here you have multiple groupe here and you can have the different active router for the two different group...so this is how you are utilising the resources...and have load sharing kind of implementation...
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
