While trying to track down a strange and unusual problem tonight, I discovered that someone is running a switch or a bridge between mae-west and the Palo Alto Internet Exchange. After adding an ip address 198.32.176.222 255.255.255.0 sec to my mae-west router, I was able to: mae-west#ping 198.32.176.252 Type escape sequence to abort. Sending 5, 100-byte ICMP Echoes to 198.32.176.252, timeout is 2 seconds: !!!!! Success rate is 100 percent (5/5), round-trip min/avg/max = 4/109/524 ms mae-west#sh ip arp 198.32.176.252 Protocol Address Age (min) Hardware Addr Type Interface Internet 198.32.176.252 0 0800.2bb6.b8f7 SNAP Fddi4/1/0 mae-west# If you are trying to track down unusual problems between mae-west and PAIX, you might want to check this out. Of course, IMHO, the bridge should be taken down or severly filtered. On the other hand - it does mean that everyone only at mae-west should immediately apply for PAIX IP addresses :-) -- Dave Rand dlr@bungi.com http://www.bungi.com
