Hi Ron,

I was thinking of broadcast and multicast routing updates only. Most
systems are on switches, and didn't really want to suggest playing games
with redirecting switched traffic to learn src/dst ip addreesses. ;->

Another way to obtain the routing table, would be to to probe the routers
for default snmp strings.

if you are local, is it not better/easier to start by tossing the nick
into permicuous and seeing what yer sniffer can discover on it's own?


Perhaps that's what you meant by looking for routing traffic?

Thanks,
