Hi

It entirely depends on the presentation from your WAN provider. If you Flex/LES connections, these present as ethernet so you can just connect these straight into your router / switch.

Whether you route over the connection or switch over the connection again depends on what you have agreed with your provider but you can do either.

With SDH you can run ethernet over that as well, again you can often specify the presentation you want.
