I am setting up a new office and need some help with the configuration of our switches.
Basically we have a main office on one subnet and want the new site to have 2 seperate subnets for each floor.
I know this should be possible with VLAN's but once I've setup the trunk groups I get lost.
I've attached a picture of the setup to give a clearer idea of what we are trying to achieve.
Any help very much apprechiated.
Thanks.
Solved! Go to Solution.

and apply spanning tree on all switches.
i didn't test it, but i hope you get the idea.
with this setup every vlan can reach the other vlans

Re: Procurve VLAN configuration
In this section;
Config default gateway 172.16.100.1
static route 192.160.50.0 255.255.255.0 172.16.100.2
static route 192.160.20.0 255.255.255.0 172.16.100.2
static route 192.160.2.0 255.255.255.0 172.16.100.2
Are you refering to setting these routes on the 172.16.100.1 device (Cisco router).
Thanks
Gordon.

Re: Procurve VLAN configuration
yes exactly.
those routes needs to be on your "default gateway".
and the default gateway for your clients is the .1 in there subnet
cheers

Re: Procurve VLAN configuration
I finally got time to try this out and it half worked. Unfortunatly I only had a small time slot for this so couldn't get much testing done.
I changed the routes on the default gateway to point to the 4204vl:
ip route 192.168.3.0 255.255.255.0 194.203.78.243
ip route 192.168.20.0 255.255.255.0 194.203.78.243
ip route 192.168.50.0 255.255.255.0 194.203.78.243
I also changed the default gateway in each DHCP scope to point to the respective IP of each VLAN on the 4204 switch.
Once done I connected a laptop to a port on in VLAN 20 on the ground floor switch and got a 192.168.3.x ip. Unfortunatly that's as far as I got. Connecting the laptop to a port on any other VLAN on the griund floor or first floor switches didn't give me an IP at all.
The configs I applied are:
4204vl:
hostname "BBP Procurve 4204vl"

Is there anything obviously wrong here or do you think the problem lies elsewhere.
We don't have a 172.16.100.x network but I used that for the default_vlan so that I could use the real IP addresses on VLAN 10 and 20. Would that cause an issue.
I'm going to have another go either later or tomorrow and I'll post if I find the problem.
thanks again.
Gordon.
