I'd like to setup an HSRP architecture between 2 6500 (MSFC2) and 1 4503 (Sup2 plus TS).
The Idea is to use 2 HSRP Groups for each VLAN. (I will have 2 gateways for each VLAN)
But I would like to know how many groups I can use on the 4503?
I found this URL for the 6500, but nothing for Catalyst 4500.
All of the supervisors support 256 HSRP groups the only exception is the Supervisor 2 which supports 16 groups only.
In the sup2 16 HSRP groups does not mean that you can have only 16 HSRP processes or 16 VLAN interfaces with HSRP enabled. So a possible approach would be for example:
Vlan 1 - standby 1
vlan 2 - standby 2
vlan16 - standby 16
vlan17 - standby 1
