forward IP multicast datagrams between OSPF

forward IP multicast datagrams between
Autonomous Systems (called inter-AS multicast
routing).
Only certain combinations of bit settings are
allowed, namely: 0 (no multicast forwarding is
enabled), 1 (intra-area multicasting only), 3
(intra-area and inter-area multicasting), 5
(intra-area and inter-AS multicasting), and 7
