csOspfNbrOptions
Module: COSINE-ORION-MIB
OID (symbolic): COSINE-ORION-MIB::csOspfNbrOptions
OID (numeric): 1.3.6.1.4.1.3085.3.1.4.2.4.1.9.1.4
Node type: OBJECT-TYPE
Type: Integer32
Access: read-only
Description: A Bit Mask corresponding to the neighbor's op- tions field.
Bit 0, if set, indicates that the system will operate on Type of Service metrics other than TOS 0. If zero, the neighbor will ignore all metrics except the TOS 0 metric.
Bit 1, if set, indicates that the associated area accepts and operates on external informa- tion; if zero, it is a stub area.
Bit 2, if set, indicates that the system is ca- pable of routing IP Multicast datagrams; i.e., that it implements the Multicast Extensions to OSPF.
Bit 3, if set, indicates that the associated area is an NSSA. These areas are capable of carrying type 7 external advertisements, which are translated into type 5 external advertise- ments at NSSA borders.
What is csOspfNbrOptions?
This Integer32 is a bit mask of the neighbor's advertised OSPF options, where bit 0 indicates support for non-TOS-0 metrics and bit 1 indicates the associated area accepts external routing information rather than being a stub area. It lets an admin infer neighbor capabilities, such as stub-area membership, directly from the options bits without separately querying the neighbor. An admin confirming a neighbor correctly recognizes its area as a stub would check that bit 1 is clear in this options field.
