I’m having trouble figuring out how to set up an AT&T OPTEMAN EVC in my home lab.
Routers r1, r2, and r3 are connected to r0 by way of the OPTEMAN circuit but they’re also connected r1<->r2 and r2<->r3 by the same OPTEMAN circuit.
I’m imagining I can set up a layer 2 switch in place of the OPTEMAN circuit but I can’t figure out how the switch would be set up. I thought if I made all the ports involved trunk ports this would work but it didn’t. Then I started thinking perhaps I need to assign VLANs to some of the ports involved on the switch but I can only assign one VLAN per port and each router has at least 2 VLANs involved so that’s not the solution.
Is it possible to set this up in a home lab? Thanks in advance.
