Hi, We have just replaced our existing DSL based VPN solution with a metro ethernet one, connecting our 3 sites together over 10Mbit links. Now i just have a simple question. The telco setup the metro ethernet (layer 2 multipoint ethernet connection between the 3 sites) and installed Nortel 1400 ESM switches at each site. After that, they were gone and could'nt tell me how to further configure it.
If i'm right, i actually have an ethernet link between every site, but i cannot just plug the Nortels in the existing switches at each site since all sites are on a different subnet, right?
So do i need an ethernet router at each site, connected between the Nortel (WAN) and the existing LAN and setup another new subnet for the "WAN net"? But what would i use as gateway at the wan ip side?
Should it be like this?
Can somebody please point me in the right direction with this, since i'm a bit new to this kind of setup?
