Are you saying you would like to filter HSRP events from crossing a user VLAN? You will need a layer 2 connection between the 6506's for HSRP. STP will determine where layer 2 traffic between the switches goes.

Q. HSRP stops working when an Access Control List (ACL) is applied. How can I permit HSRP through an ACL?

A. HSRP hello packets are sent to multicast address 224.0.0.2 using UDP port 1985. Whenever an ACL is applied to an HSRP interface, ensure that packets destined to 224.0.0.2 on UDP port 1985 are permitted.

HTH and please rate.
