Hi, This is probably a fairly simply question, I'm probably just not quite groking the layers involved here. If I had the following setup: Endstation A -- Switch A === RPR Ring === Switch B -- Endstation B could there be a VLAN setup such that Endstations A and B are both in it, and can communicate as if they are on the same LAN segment? (And I mean natively. ie. not using an MPLS VPN). ie. Will the switches involved tranlate the different framing formats in use? Is this vendor dependent? Sam
