All rights reserved 3J.4.3.2 Broadcast Distribution Table Format The BDT consists of one entry for the address of the BBMD for the local IP subnet and an entry for the BBMD on each remote IP subnet to which broadcasts are to be forwarded. Each entry consists of

15、 the 6-octet B/IP address with which the BBMD is accessed and a 4-octet broadcast distribution mask. If the IP router to the subnet performs network address translation (NAT), then the BDT entry shall contain the global IP address of the IP router.
