Did you ever find out what was causing the problem? I also have this issue on two different 7200's going to two different devices. One connects to a Ciena switch. The other connects to a Cisco ME-3600X switch. My show interface outputs are below for both routers. IP addresses have been removed. Thanks in advance for any help or insight in to this.
