I need some help configuring 2 3560's to route across a Metro E, both using port 49 with subnets 192.168.0.x routing to 192.168.1.x

Can you provide a network topology ?
What do you mean 'both using port 49' ? That port is being used for TACACS. I'm not exactly sure what you mean by that.

I need detailed help, either command line or using network assistant to configure 2 Cisco 3560 switches. What I need: to congfigure Gig Eth port 49 on both switches to route to each other. One side is on a 192.168.1.x and the other a 192.168.0.x subnet. The switches sit on opposite ends of a Metro E PtP.

Your provider is offering layer2 or layer3 Metro Ethernet ?
Remember both switches aren't connected directly to each other via switchport G0/49, but they are actually using other switches in transit.
If they provide layer2 MetroE, you need to know the access Vlan they've provided for your configuration. If they provide layer3, some guidelines from the provider must've been given in term of addressing.
Once you get that information, post back.

It is a layer 2 MetroE.

You need to get the 'transit vlan' information from your provider, then on the switchport G0/49 you would configure something like this:
interface g0/49
switchport mode trunk
switchport trunk native vlan [transit vlan from provider]
! prune your Vlans !
switchport trunk allowed vlan [vlan-id]

I think mostly the service provider has given you a P2P connection over his ME backbone
Just configure the ports on the switches as routed ports and you should be good to go.
On switch 1
int g 1/0/49
no switchport
ip address 10.10.10.1 255.255.255.252
ip route 192.168.1.0 255.255.255.0 10.10.10.2
On switch 2
int g 1/0/49
no switchport
ip address 10.10.10.2 255.255.255.252
ip route 192.168.2.0 255.255.255.0 10.10.10.1
If it is a true Layer 2 metro service then the configuration would be similar to the one posted by Edison

On your last line there "[vlan-id]" is that the native vlan on the switch or the providers?
10-24-2007 07:18 PM
That's the list of Vlans you want to allow on this trunk. The provider's Vlan should be included.

Ok I just got word the MetroE is up and it has been setup with a dot1q tunnel. How does that change my configuration?

On one side the default gateway is the firewall, on the otherside of the WAN it is the PTP router. If I trunk this connection, what will I setup in place of the gateway on the side with the router?
