| Description | A Bit Mask indicating whether the router is
forwarding IPv6 multicast datagrams
based on the algorithms defined in the Multi-
cast Extensions to OSPF.
If intraAreaMulticast set, indicates that the router
can forward IPv6 multicast datagrams in the router's
directly attached areas (called intra-area mul-
ticast routing).
If interAreaMulticast set, indicates that the router
can forward IPv6 multicast datagrams between OSPFv3
areas (called inter-area multicast routing).
If interAsMulticast set, indicates that the router can
forward IPv6 multicast datagrams between Auto-
nomous Systems (called inter-AS multicast rout-
ing).
Only certain combinations of bit settings are
allowed, namely:
- All bits cleared (no multicasting)
- intraAreaMulticast only,
- intraAreaMulticast and interAreaMulticast,
- intraAreaMulticast and interAsMulticast
- intraAreaMulticast, interAreaMulticast and
interAsMulticast
By default, all bits are cleared. |
