This read-only object identifies the virtual channel identifier for the multicast forward VCC, paired with busMultiFwdVpi. Because LANE typically uses a single point-to-multipoint connection from the BUS to all clients for this purpose, this VC carries every client's broadcast and multicast traffic simultaneously, so congestion or errors on this specific VC affect the entire emulated LAN's broadcast delivery at once, not just one client. Cell loss specifically on this VPI/VCI pair, rather than on individual clients' unicast VCs, would degrade broadcast delivery to every LEC on the ELAN simultaneously.
