I mean it all kind of makes sense but I'm not sure what my retention is going to be on this particular chapter. I'm hoping that if I can plow through and get some of it that in later chapters it will all just click.

The label switch controller (LSC) is a piece of hardware designed to perform the control plane functions needed to make the ATM switch an ATM LSR. The Cisco BPX is an ATM switch that needs an LSC to become an ATM LSR. The LSC takes care of the control plane functions like the IGP, the routing table, and LDP. The PBX still performs the switching of the ATM cells in the data plane. In the case of the BPX, the LSC is a Cisco 7200 router. The LSC controls the BPX through an ATM interface over which the Virtual Switch Interface (VSI) protocol is running. VSI allows the router to control the ports, trunks, or virtual trunks on the BPX. The result is the same as if the LSC were internal to the ATM switch. When a PBX has an LSC attached to it, it becomes an ATM LSR for all intents and purposes. The LSC creates cross-connects in the switching fabric of the BPX for the LVCs. The interfaces are presented to Cisco IOS as XTagATM (extended label ATM) interfaces on the LSC.
