Two default gateways via different lan cards

[Lora Ganeva]

Hi,
I have an HPUX 11i with two lan cards in different gateways.
I want to configure the server to have two different default gateways, but i would like lan0 to be the first and lan2-the second and lan2 to be used only if lan0 is down.
Although I have configured the first defualt route via lan0 with route count 1 and the second - with route count 2, the second is always put before the first(via lan0) in the routing table.
What could be the reason for this?
Any help would be greatly appreciated.

Hi,

ROUTE_DESTINATION[2]="default"
ROUTE_MASK[2]=""
ROUTE_GATEWAY[2]=""
ROUTE_COUNT[2]="1"
ROUTE_ARGS[2]=""

must exist in /erc/rc.config.d/netconf for the
lan2

Hi

I'm not sure, but maybe everything is as you expect? What do you mean 'put second before first in routing table'? Do you mean it shows up earlier in netstat -r? But does it really matter?
The important thing is which one is chosen. You should check routing done for real connections rather than 'what comes first in report from netstat -r'.

My 2 words. Please don't kill me if I'm wrong. :)

Good luck

I don't think the order really matters. Do a traceroute to remote host where it has to use the default and see if it looks like it is using the correct lan.

You can also try
netstat -rnv

and see if it gives you the correct usage info. (It's sort of broken in 11.0)

Hi,

traceroute is kind of "broken" in 11i.
If you just do a normal traceroute it will *try* to go out the first device displayed in a netstat -in output.
You have to force it out the proper lanX device with -i.

Not sure what's broken, but it's a major pain for us as ALL our servers have multiple I/Fs - 1 for public IP & 1 for bulk-data xfer (our dedicated backup network).

I thought you can only have one default route. If you want others, you have to add static routes. But I could be wrong.....
