I'm trying to be able to trunk a subinterface of a router (router on a stick) and I'm having a tough time understanding what IOS and type of router that will support this command. I've tried in one 2611 router but the command is not available, but I can't figure out which IOS I need in oder to do that. Any help would be greatly appreciate it.
