Dear Community,
I am using HP ProCurve 3500yl (J8692A) for my research and now I am trying to build a topology for my experiments. I stuck on configuration of routing between separate VLANs on the same switch. I have built a minimal example to show my problem and ask you for help.
The question is: How to configure the network so that the address 192.168.2.2 can ping 192.168.6.2 ?
Topology picture: http://img801.imageshack.us/img801/1830/ntw.gif
I think, I have tried everything.
The current status of pings is the following:
192.168.2.2 (relate2) --> 192.168.2.1 (sw2 VLAN2) OK
192.168.6.2 (relate6) --> 192.168.6.1 (sw2 VLAN6) OK
192.168.2.2 (relate2) --> 192.168.6.1 (sw2 VLAN6) NO!
192.168.6.2 (relate6) --> 192.168.2.1 (sw2 VLAN2) NO!
Switch can ping every address (2.1, 2.2, 6.1, 6.2)
Configurations:

Re: 3500yl (J8692A) Cannot setup routing between VLANs
HI
The above configuration looks fine but we can check few things:
1) Why do you need static route between VLAN's?
"IP ROUTING" command should enable inter-vlan routing automatically)Although the switch will use the connected route because he had better metric but still please try to remove it and look if it works).
I can see 2 interfaces on your pc's, their are both linux? Can you please tell me which version?
From a briefing view the switch looks fine and i suspect that the problem is on your clients.

Re: 3500yl (J8692A) Cannot setup routing between VLANs
Hi,
thanks for your reply. I also though, that just typing in the "ip routing" would work. I added the other routes just to try some other possibilities – I am struggling with this for two days already.
My hosts are both Ubuntu server 12.10 and I had no problems with them until now. Physically these are Dells R210II, each with 4x1Gb NICs. If I connect them using a single VLAN pings are working. Which other information from the hosts do you require to point some solution possibilities?
I wonder if the version of software can play a role here (basic vs. premium). I saw that basic should also support routing. By the way I updated the firmware to K.15.10.0016 but the situation remains the same.

Re: 3500yl (J8692A) Cannot setup routing between VLANs
Have you tried to add default route to the second linux machine? "relate-6".
I can see default route on the first machine and more specific route on PC 6, please try to add default:
route add default gw 192.168.6.1.
I had problem with Red-hat machine with few interfaces, please try to remove any other interface except 192.168.x.x.

Re: 3500yl (J8692A) Cannot setup routing between VLANs
You are right. Thank you!
The Management VLAN was the cause of these problems, when I changed it to vlan 1 it started working.
Static routes on the hosts are ok, deafult gateway must also be like it is, because it give the two hosts (out of many) the access to the external network.
Now I come back to my original topology. By keeping trying with this one I learnt a lot, so I will configure the new one much faster :)

Re: 3500yl (J8692A) Cannot setup routing between VLANs
No other networks in your draw so i didn't knew that you need more routes :)
Nice experience for you, keep going!
