I am using a 4500 with a Fast Ethernet interface and would like to be able to route between VLANs that are setup on my 2900. I don't have the option to use encapsulation ISL using Ver 11.2 on the 4500. Do I have to upgrade to 11.3 or something higher to be able to use ISL? Thanks! _________________________________ FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
