Hi,
My question is if we have to configure also the spoke routers with the same type of logical sub-interface that we use in the hub? In other examples, and I used it as well on GNS3, I configured my hub router with logical sub-interfaces (point-to-point)/(multi-point) but for the spoke routers I always used the physical interface regardless the setup on the hub router. Is this approach correct ? Thus my configuration on the spokes was always done with the "frame-relay map ip ", which I take into account both for the hub router and rest of spokes. Thus I use it as many times as necessary, and the difference is in the . However, in your examples, you use also sub-ifs on spokes, so to conclude what’s the correct approach for the spoke routers? Physical or logical sub-ifs ?
