I am trying to setup a Vlan via a WAN Link. Local End has already 4 VLANs. Remote End doesn't. Remote end needs to access VLAN id 4 via the WAN link. Local Gateway router = Cisco 3660 Remote Gateway Router = Cisco 3660 Local Switch = Cisco 3750 Remote Switch = Cisco 2924 What is the config that needs to be configured on the two routers and switches for VLAN to be accessible at Remote end. Note Local end - 160.8.32.0 Remote end - 160.8.24.0 thanks

Thanks. We'll let you know when a new response is added.

Are you running multiple VLANs in both locations? If so, you may want to encapsulate the traffic in a tunnel. Be aware that running the same VLANs on two sites with the router for those VLANS at one site will make routing for the other site a real pain.
If not multiple VLANs, the simplest solution would usually be to dispense with the VLAN and route traffic normally.
I have never run VLANs across a WAN and would avoid if I could.

    Im not sure how you are configured but it will be a given that your remote router has a WAN Interface IP address that you can route traffic to, your router on the local wnd has its WAN interface ip. you mentioned that local was 160.8.32.0 what is the subnett of your VLAN #4? what ever that subnett is you need a static route on the remote side telling the router to send traffic to the VLAN's subnett using the 160.8.32.1 router. Now you proboly have the switch doing the VLANing. you need to make the config on the switch using 802.1q tagging so that the port that connects the local router into the switch also allows traffic to the VLAN #4 over that same port. Are you with me so far? reply and let me know if your lost or if you fallow. Cause that is not exactly the play by play you might need.
