dynamic routing HP-UX 10.20

[Duane Von Lanken]

How can I stop a DNS caching server from learning dynamic routes. There is no routing protocol running on the server, I have two NIC cards lan0 and btlan01 config'd and are on the same LAN segment.

A stab in the dark here:

Does your gated.conf have a line: rip yes

HTH,
Paul

[Duane Von Lanken]

No - rip stmt - the following is from netconf file:
GATED=0
GATED_ARGS=""
I have also verified running processes that no routing daemon (gated, rip, etc) is running.

[Duane Von Lanken]

Sorry - I looked at the gated.conf file, YES it does have a 'rip yes' stmt. Should I change and reboot? gated is 0 and it shouldn't even access this file?

Duane, HP-UX routing facilities provide simple dynamic learning of routes based on packet transmission. It does not speak RIP, IGRP, EIGRP, OSPF or other routing protocols and cannot send and receive advertisements (broadcasts) from/to these protocols. rdpd will allow your system to do this. however, you don't need rdpd running to learn routes dynamically... it will just hapen and DNS will cache over these routes. I do not know if this can be turned off.

Nope, it can not be turned off on the server. Usually these routes can from the router who is using IGRP or another protocol to send these dynamic routes. So, if you turn this off on the router it would go away.

We have the same problem and turning off IGRP is not an option, so we have a cron job that does a netstat -nr and removes routes that we do not want.
