Multiple Gateway IP's

Gear Fisher — Tue, 30 Jan 2001 17:05:57 GMT

How can I add multiple gateways to HP-UX 10.2? Obviously I can add a single default gateway, but would like to enter a secondary "failover" gateway should the first have a problem.. please help...

Thanks!

This will not work on 10.20, but will at 11.0. On 11.0, in your /etc/rc.config.d/netconf, you would have multiple instances of routes like so

ROUTE_DESTINATION[0]="default"
ROUTE_MASK[0]=""
ROUTE_GATEWAY[0]="10.44.176.1"
ROUTE_COUNT[0]="1"
ROUTE_ARGS[0]=""

ROUTE_DESTINATION[1]="default"
ROUTE_MASK[1]=""
ROUTE_GATEWAY[1]="12.56.154.1"
ROUTE_COUNT[1]="1"
ROUTE_ARGS[1]=""

If your routers support it, you migth consider running the router discovery protocol daemon. It will pick the "best" default route to use at any given point in time. I beleive that you can edit onr of th econfig files in /etc/rc.config.d/ to enable the daemon.

Hello,

The router discovery protocol daemon (rdpd) is obsolete in HPUX-11 says the rdpd man page.
My question is: when multiple deafult gateway are configured, is there a way to set a priority for the gateways. For instance, use gateway A first and when that one fails, use gateway B ?
I ask this because we have configured two default gateways on different subnets of which one is not meant for 'user' traffic, so we want to have the other gateway as primary.

Thanks in Advance,

Mark

Enabling GATED will let the machine select a different gateway is one is down. I do not know how to select primary and secondary roles.

By default, 11.0 will try another default gateway if the other is down.
