dot1q problem [7:43392]
Hi, We have two 6506 switches with MSFC cards. One is HSRP active router and the other standby, and these switches are connected to each other with trunk links. When we configure dot1q on these trunk links, both routers(MSFC cards) declare themselves as HSRP active router on Vlan1, and the devices connected to different switches on Vlan1 can not communicate with each other. I didn't see any problem on other Vlan's. When we configure ISL on these switches, everything works fine. Vlan 1 is the default vlan for these swiches and the trunk ports are the members of Vlan1. Any Ideas?

RE: dot1q problem [7:43392]
The only issue I can think of in dot1q vs ISL is the native vlan. If the native vlan is set to something other than default (which is Vlan1) on one end of the trunk, and not on the other, then the 2 routers would not be on the same subnet and would behave the way you describe. One way to check this is to remove see if you can ping the real ip address of each router from the other while dot1q is up. If you can't than there must be something wrong with the trunk.
