Default route problem with procurve 2650

Hi all,
i have a strange problem on a 2650 switch with 2 vlan defined and ip routing enabled:

under config i set ip default route with:

ip route

when i get the config with the sh conf or sh run command it display me the default route, but if i look at the routing table (with the sh ip route command) it does not show me the default route.

if i go to the conf and disable ip routing

then the show ip route does show the default route...

any ideas?
may be an hardware problem?

Thanks in advance.


firmware is at 10.38 level (just upgraded, but the problem persist)

Re: Default route problem with procurve 2650

This looks to be similar to this thread:


What I'm suspecting is that by the time the switch has initialised all the way up to port 50, something has timed out and the route is not added.

As a workaround, to get VLAN 2 to come up quicker you could either move the the port from 50 to port 1 (but then you won't get the gigabit uplink), or just to prove this theory tag port 1 for VLAN 2. That way as soon as port 1 comes up, it bring up both VLANs.

Regardless of if this helps or not, I think you should contact HP support about it.

Re: Default route problem with procurve 2650

Hi Bruno,

I'm pretty sure this issue is being caused by both a default gateway being defined and ip routing turned on.

From memory Procurve switches do not support both functions simultaneously, disable the default gateway and the route should stay.

I also recall the switches not allowing you to do this and generating an error immediately but it seems on the newer firmware having the two commands is possible. Perhaps support for both functions has been added, I guess I should go check the release notes and find out...

Hope this helps!
