If they are then you will need to place these hosts in different subnet from the others and configure the 3550 to perform IPv6 routing, which is not possible with an IP base feature set. So you will need to check and see what type of license you have installed on your layer 3 switch and ensure that it supports IPv6 routing.Also despite what Cisco says IPv6 support on their switching platforms is spotty at best and buggy at worst. You might want to try using your 2811 or some other software based IOS router to route between the VLANs just to test things and see if it is an issue with the 3550 itself.If you could post the running configuration of the 3550 and the 2811 it would be very helpful.Edit: It looks like your 3550 may be out of luck when it comes to IPv6 support: http://www.ine.com/resources/ccie-3560-3550.htmYou should still be able to use the 3550 as a layer 2 device for IPv6 traffic though, you will just need to do all of the IPv6 routing and filtering on the 2811.
