Just because its not configured or not configurable doesn't mean its not actually doing it (it may be a bug). I have an Ethernet over FrameRelay Radio PTMP system that after a few months of uptime inserts the UDP payload of customer A into the TCP payload of customer B (customer B using this TCP session to transfer files to a AS400 that doesn't check TCP checksums and therefor the UDP payload of customer A makes it into the application of customer B). The only fix here is to reload the whole system. The very same PTMP system sometimes drops traffic of a certain mac address, although there are no layer 2 rules (other that different vlans). Just because the box isn't supposed to interact with a specific OSI layer doesn't mean its not actually doing it. 2 suggestions: - use point-to-point OSPF links for everything (especially for WAN links) - exclude your WAN link in your testing Regards, Lukas _______________________________________________ cisco-nsp mailing list cisco-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
