Saving routing table

Ashok K Gurung — Wed, 30 May 2007 06:49:41 GMT

Hi

we are having problem saving static routing table.

We used command "ip route 0.0.0.0 0.0.0.0 172.16.32.1"

172.16.32.1 is our firewall. we used command like write memory but when ever we reboot switch for some reason route we enter will be disapear.

is there any thing we need to do to save this thing parmanently?

we will appreciate if any one could advice us on this.

Thank you

That's strange, which switch are you using and have you updated the firmware to the latest version?

Yes that is what i am thinking

We have just installed latest version below is our firmware info

Image stamp: /sw/code/build/alpmo(m35)
Apr 13 2007 14:19:50

Thank you

After you do the write memory is the startup config updated?

Hi again

What is the cammand to see what is in startup config?

When i do write memory everything else gets saved e.g. vlan setting so on

I am not sure if this related or not we do not have any rip, pim or ospf enabled. we just have IP routing enabled and that just need to do intervaln routing.

We needed this on to work as default gateway to the outside world.

Thank you
Thank you

Should be just a "show startup-config", also a "show running-config status" should tell you whether there are differences between the startup and running configs.

Hope this helps!

Hi & Thanks for your reply again

there is no command "show startup-config" availabe to us but when we chaecked with "show running-config status" it says "Running configuration is same as the startup configuration."

I am not sure where did we do wrong.

Thank you

Sorry my mistake, it should be just a "show config" to see the startup config, am doing this from memory.

Ashok K Gurung — Thu, 31 May 2007 02:02:00 GMT

yes i can see route entry when we do show config

Thank you

Ashok K Gurung — Thu, 31 May 2007 02:08:53 GMT

Hi again

We just restarted our switch and it went back again but this time i went and ran command "show config" it actually shows route entry but if i do show ip route it doesn't show route entry and it stops routing to external network.

Thank you

That's really strange... I'd personally try resetting to factory defaults and redoing the config but from your posts the switch is in production.

Have you contacted HP support?

Re: Saving routing table

Matt Hobbs — Thu, 31 May 2007 09:20:47 GMT

I agree with Joel. One thought that I have is that maybe the interface that connects to where the route is destined, is coming up too slow which is causing it not to be added to the routing table.

In the past I've seen issues with SNMP trap destinations and how it would determine the trap-source based on the interface that came up first. A workaround for that was to change the port and disable passive lacp to ensure the port comes up quicker.

Right now I would recommend trying an older version firmware, if the problem is still there contact HP support with all the testing you have performed so far.

Do you have IP routing and a default gateway enabled in your config??
