route change

[Warren griggs]

Hi,

I need to change my default route on a server and can't really get any downtime for it. I know on Solaris you can user "route change" but I've noticed on the HPUX man page there is only "route add" and "route delete".

What is the best way I can change this on the fly??

Thanks in advance,

Colin.

Colin,

You'll need to delete it, then re-add it.

You can use route add then route delete. Can be done on the fly. If you want to keep the change and make it perminent you will also have to edit /etc/rc.config.c/netconf.

Hi Colin


All you need is to

route delete < IP ADRSS>

route add < IP ADRESS>

Ok I caught the typo:

/etc/rc.config.d/netconf

Pete,

Won't this stop all traffic going to the default route until I re-add it?

Is it ok to do as long as I do it quickly?

Thanks,

Colin.

hi,

In man 7 routing, you can read that it's possible to have multiple default routes :

There may still be multiple routing entries remaining. In that case the IP packet is routed over the first entry displayed by netstat -r.
Such multiple routes include:

+ Two or more routes to a host via different gateways.
+ Two or more routes to a network via different gateways.
+ Two default routes.

So in your case, you can add the new defalut route, then delete the old one.

Regards.

Colin,

I guess it's been covered but, since you asked, add then delete should do the trick.

Make sure you're on the system console when you do it, or you'll be cutting yourself off at the knees. ;)
