Hello everybody,

I have a short question. When using EOIP tunnels you have, as far as i understand, setup one pair of tunnel ends per client. Is that right or could I use one EOIP interface on the server and one for each client connecting to the interface on the server?

Best regards

You can set up as many EoIP tunnel pairs as you want if you keep incrementing the tunnel id field on each pair of EoIP tunnels. You have to build a new server side EoIP interface for every client though. If you want Layer 2 multipoint then you need VPLS.

I have no idea how to implent MPLS/VPLS in our heterogenous netwok topolgy. And as far as I can see you need direkt WAN access for MPLS, something I can't provide on lasmost all our locations we usually sit behind a nat.
Are there any alternatives?

Best regards

When direct Layer2 access is not available, we frequently run EoIP on top of a layer 3 network and then implement MPLS/VPLS. It may seem like a lot of layers, but it is the best way to deploy multipoint layer 2 since VPLS has a split horizon loop prevention mechanism and EoIP does not.
