Re: hsrp isl trunking [7:58144]
Dennis, It's better to have a unique HSRP group for each VLAN. Cisco bases the virtual MAC address on the group. If you reuse the group number, you'll have duplicate MAC addresses. Granted, they're on seperate VLANs and shouldn't matter, but I had a Cat4000 that didn't like it at all, and gave me lots of logged messages about MACs moving around.

And.. on the new msfc-2 you only get 16 hsrp groups supposedly the issue that chuck states below is not an issue with the new msfc-2 for the 6509's Chuck Church wrote: Dennis, It's better to have a unique HSRP group for each VLAN.

Re: hsrp isl trunking [7:58144]
I think the 'use-bia' may have been a fix for the problem as well. It's been a while since it happened. For all I know it might have been a problem with the CatOS on the switch.
