Q. What is the maximum number of HSRP group IDs supported
16 unique HSRP group IDs can be created in a switch or Supervisor
What is the implication of using the same HSRP group ID on multiple interfaces?
A. When you define the same HSRP group ID on multiple interfaces, they share the same HSRP virtual MAC address. In most modern LAN switches, there are no issues because they maintain a per-VLAN MAC address table. However, if your network contains any third-party switches, which maintain a system wide MAC address table regardless of VLAN, you can experience problems.
Can I only configure a total of 16 HSRP VLAN interfaces or 16 HSRP processes in the Supervisor Engine 2-based system?
A. No. You can use the 16 unique group IDs on as many interfaces as you like. 16 HSRP groups does not mean that you can have only 16 HSRP processes or 16 VLAN interfaces with HSRP enabled. The only caveat is that you can only define up to 16 HSRP processes per interface. However, it is very unlikely that you would need more than 16 HSRP processes per interface in a well-designed network.
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
