How to change default route?

Hello,

I have an rx3600 server with hpux 11.31. In the two network interfaces, lan900 and lan901. When I run netstat-rn I see that the default route is on the lan901.
In the netconf file is established lan900.
How I can change it for the default route is in the lan900?

Thanks,
Jesus

I can't see anything. Perhaps you could show
us what you're talking abut?

As usual showing actual commands with their
actual output can be more helpful than vague
descriptions and interpretations.

> In the netconf file [...]

I can't see what's there, either.

Your APA is failed over to 901. Try to create a LAN monitor failover group to switch between both groups.

I want to change the default route, remove lan901 and put the lan900.

Re: How to change default route?

Hi Jesus

This is Judas writing :) ..


I will try to give you a help.


In the /etc/rc.config.d/netconf you configure the defaultroute for you lan.

Example of the configuration of two network cards in netconf:

INTERFACE_NAME[0]=lan0
IP_ADDRESS[0]=xxxx.xxxxx.xxxx.xxxx
SUBNET_MASK[0]=aaaa.aaaa.aaaa.aaaa
BROADCAST_ADDRESS[0]=""
INTERFACE_STATE[0]=""
DHCP_ENABLE[0]=0
INTERFACE_MODULES[0]=""


DEFAULT_INTERFACE_MODULES=""
INTERFACE_NAME[1]=lan1
IP_ADDRESS[1]=xxxx.xxxx.xxx.xxx
DHCP_ENABLE[1]=0
SUBNET_MASK[1]=aaaa.aaaa.aaaa.aaaa
ROUTE_MASK[0]=aaaa.aaaa.aaaaa.aaaa
ROUTE_GATEWAY[0]=xxx.xxxx.xxxx.xxx
ROUTE_COUNT[0]=1
ROUTE_DESTINATION[0]=default


This configure the default gateway for lan0,

To configure to lan1 I think this should work
ROUTE_MASK[1]=aaaa.aaaa.aaaaa.aaaa
ROUTE_GATEWAY[1]=xxx.xxxx.xxxx.xxx
ROUTE_COUNT[1]=1
ROUTE_DESTINATION[1]=default

Hope this help.

Re: How to change default route?

this happens if you have two or more interfaces on the same subnet..

who knows which interface will get the route

I know this works for windows and maybe linux but I do not think HPUX likes this...

10.X.2.82 10.X.2.82 UH 0 lan900 32808
10.X.2.85 10.X.2.85 UH 0 lan901 32808

not sure of the purpose of having two separate aggregates on same subnet.. I would think that the correct config if attempting to span two disparaging switches is to have 2 aggregates with the second one acting in a LAN_FAILOVER mode.

or cascade the switches and aggregate them all as one...

maybe I am miss interpriting something ..
