This read-only object identifies the virtual path identifier for the multicast forward VCC. This is the specific virtual path the BUS uses for the one-to-many connection it maintains to distribute broadcast and multicast traffic out to all connected LEC clients, so it's the value to cross-reference, along with busMultiFwdVci, when tracing exactly which VC on the wire carries this ELAN's broadcast traffic for packet capture or fabric-level troubleshooting. Capturing cells on this specific VPI/VCI pair at the ATM interface would show exactly the broadcast and multicast traffic this BUS is fanning out to its LEC clients.
