Description: A Bit Mask indicating whether the router is forwarding IP multicast (Class D) datagrams based on the algorithms defined in the Multi- cast Extensions to OSPF.
Bit 0, if set, indicates that the router can forward IP multicast datagrams in the router's directly attached areas (called intra-area mul- ticast routing).
Bit 1, if set, indicates that the router can forward IP multicast datagrams between OSPF areas (called inter-area multicast routing).
Bit 2, if set, indicates that the router can forward IP multicast datagrams between Auto- nomous Systems (called inter-AS multicast rout- ing).
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 (multicasting everywhere). By default, no mul- ticast forwarding is enabled.
What is csOspfMulticastExtensions?
This Integer32 is a bit mask indicating which multicast OSPF extensions this router supports, with bit 0 covering intra-area multicast forwarding and bit 1 covering inter-area multicast forwarding. It tells an admin whether this router can actually participate in multicast routing extensions to OSPF, which matters for deployments carrying IP multicast traffic like video distribution. An admin troubleshooting multicast that fails to cross an area boundary would check whether bit 1 is set on the router at that boundary.
