Static routes move to lo0

[Hector Vargas]

I have a problem with hpux11.11.

I define static routes on /etc/rc.config.d/netconf and reboot my server but when I try to delete the route, I get a meesages "route does not exist.

dsudsas1:/etc/rc.config.d/OLDNETCONF # netstat -rn

what it shows with ifconfig lan2 ? Try to take lan2 down if it is not in use.

ifconfig lan2 unplumb

netstat -rn

Just saw your subject line that you want to move static routes to lo0?

Routes for any 127.*.*.* loopback destination cannot be added or
deleted.

Here is:

Yes, during troubleshooting I connect on the serial connection and unplumb all the interfaces and I notice that the default route move to lo0 interface and will not allow me to delete it.

==================

It shows it removed entries for lan2 now. So what are trying to do now?

[Hector Vargas]

Here is an example of what I see.

unplumb interface lan1 and the default route moves to lo0

If you network cables properly hooked up and netconf configured well then it would be cache. Clear cache using arp -d command.

restart network.

I need to add "host" on my netconf file.
