basOspfMulticastExtensions
Module: BAS-OSPF-MIB
OID (symbolic): BAS-OSPF-MIB::basOspfMulticastExtensions
OID (numeric): 1.3.6.1.4.1.3493.2.7.7.1.1.1.12
Node type: OBJECT-TYPE
Type: Integer32
Access: read-write
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 basOspfMulticastExtensions?
This read-write bit mask controls which forms of IP multicast forwarding the router performs under the Multicast Extensions to OSPF: bit 0 enables intra-area multicast forwarding, bit 1 enables inter-area, and bit 2 enables inter-AS. For example, a value of 3 enables both intra-area and inter-area multicast forwarding, while 0 (the default) disables multicast forwarding entirely.
