Hello, I am having trouble with my network. We have all cisco gateways, and all are above software rev 8.0. I am using NetCentral to monitor all this. When I show the routing table from NetCentral it gave the routing table with an entry of Destination being 0 .0.0.0 This is a little wierd. It may be a broadcast address (except it's really all ones), or it could be the weather... Whatever caused it I can't see that entry on the gateway now. So it was either there and dissapeared or never there in the first place. any ideas Kevin Quinn 11426 Rockville Pike, Suite 400 Computer Specialist Rockville, MD 20852 Henry M.

Actually, 0.0.0.0 is the numeric notation for the "default" address - the address to send packets that aren't matched by any other network routes. You may want to look at RFC1058 - it's included in the default GateD distribution - there's mention of the 0.0.0.0 notation. Yes, it is somewhat strange - I'd first been confused by this as well - and it's not a broadcast route, though it'd initially appear to be so. But then, a lot of things in TCP/IP are non-orthogonal, and non-predictable. Also, Doug Comer's book "Internetworking with TCP/IP" covers this as well, I believe. -rich --- rich scott rich@rx7.osa.com open systems architects, minneapolis 612/525-0000
