It has been mentioned a few times on the list, but nothing seemed to change. So, rather than put the configuration in a note somewhere (and lose it) I just shut them down. (I can't grasp the concept, it's either up and working, or not at all?) When I do something like "show decnet interfaces" those tunnels that are not working show up as 2 lines, rather than several. There are other reasons too, but this is what works for me :-) You can put an IP address here, the same way as destination, and I could check if I had teh corresponding tunnel. I don't use the IP as my Cisco 1841 (previously a DECbrouter90) is behind a Cisco 800. However, my static IP is: 120.146.225.243. This does *NOT* work on the boxes I have, they are to small to run the newer SW. (This is a no_op anyway, as there is no fragmentation code, if the path_mtu is smaller than 576+gre+ip, packet is lost...) I had the same issue when I was originally running my DECbrouter90 (before the power supply gave up). I have switched this option off. Regards, Tim.
