Connecting two locations over metro ethernet
I have a seperate subnet at each location. I'd like to keep the subnets addressed as they are now. The metro ethernet is presented to me as a cat5 connection. I can connect a laptop on each end of the connection, put them on the same subnet and ping each other. I was told by the provider they are set up in a hub and spoke type configuration.
My main location is 10.1.1.0/24 and has a 2910al. The two remote sites are 10.1.4.0/24 and 10.1.6.0/24 and they have 2610's installed.
My plan is to plug the cable I am presented with into port 1 of each switch and config them like such
Main Router:
ip routing
vlan 1
untagged 1-24
ip address 10.1.1.1/24
exit
vlan 6
name "location6"
tagged 1
ip address 10.10.6.1/24
exit
vlan 4
name "location 4"
tagged 1
ip address 10.10.4.1/24
exit
ip route 10.1.6.0/24 10.10.6.2
remote switches:
vlan 1
untagged 1-26
ip address 10.1.6.1/24
exit
vlan 6
name "location6"
tagged 1
ip address 10.10.6.2/24
exit
ip route 10.1.1.0/24 10.10.6.1
Am I on the right track here? I tried variations of the above configurations and couldn't get it to work. Do I need other static routes or something? Is the tagging right? I'm not real clear on that subject either. Any help is appreciated.

Re: Connecting two locations over metro ethernet
Good help is hard to find on a weekend. I searched all over the net for answers and read the manuals I found for the 2910al and I finally got everything all set up. I thought I would put up my configs and mention some pitfalls for anyone who might be searching for a solution to a similar scenario.
I struggled for hours with different configurations before and after my first post before I figured out my service provider wasn't passing the VLAN tags my switches were creating. Having that set up right to being with would have saved me a lot of time, but I probably wouldn't have learned as much as I did.
My firewall at the main site is 10.1.1.1
My DHCP server is 10.1.1.6.
The trunks in the coreswitch are aggregate links to racktop swtiches.
Vlan 1 is unused all of the switches. There are no ports assigned to them. I gave them bogus IP addresses because I didn't want them grabbing on from my dhcp server, I guess. I doubt that's a best practice, but it works for me.
I welcome any criticism. I'm still learning. Thanks for looking.
