prvtOspfMulticastExtensions
Module: PRVT-OSPF-MIB
OID (symbolic): PRVT-OSPF-MIB::prvtOspfMulticastExtensions
OID (numeric): 1.3.6.1.4.1.738.1.6.4.2.1.10
Node type: OBJECT-TYPE
Type: Integer32
Access: read-only
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 prvtOspfMulticastExtensions?
This read-only bitmask reports which Multicast Extensions to OSPF (MOSPF) capabilities the router supports: bit 0 for intra-area multicast forwarding, bit 1 for inter-area, and bit 2 for inter-AS; only the combinations 0, 1, 3, 5, and 7 are valid, and 0 (no multicast forwarding) is the default.
