| RouterId |
| A 32-bit integer uniquely identifying the router in the Autonomous System. By convention, to ensure uniqueness, this should default to the value of one of the router's IP interface addresses. |
| AdminStat |
| The administrative status of OSPF in the router. The value 'enabled' denotes that the OSPF Process is active on at least one interface; 'disabled' disables it on all interfaces. Enumerations: |
| VersionNumber |
| The current version number of the OSPF protocol is 2. Enumerations: |
| AreaBdrRtrStatus |
| A flag to note whether this router is an area border router. Enumerations: |
| AsBdrRtrStatus |
| A flag to note whether this router is an Autonomous System border router. Enumerations: |
| ExternLsaCount |
| The number of external (LS type 5) link-state advertisements in the link-state database. |
| ExternLsaCksumSum |
| The 32-bit unsigned sum of the LS checksums of the external link-state advertisements contained in the link-state database. This sum can be used to determine if there has been a change in a router's link state database, and to compare the link-state database of two routers. Range: 0 to -1 |
| TOSSupport |
| The router's support for type-of-service routing. Enumerations: |
| OriginateNewLsas |
| The number of new link-state advertisements that have been originated. This number is incremented each time the router originates a new LSA. |
| RxNewLsas |
| The number of link-state advertisements received determined to be new instantiations. This number does not include newer instantiations of self-originated link-state advertisements. |
| ExtLsdbLimit |
| The maximum number of non-default AS- external-LSAs entries that can be stored in the link-state database. If the value is -1, then there is no limit. When the number of non-default AS-external-LSAs in a router's link-state database reaches ospfExtLsdbLimit, the router enters Overflow- State. The router never holds more than ospfExtLsdbLimit non-default AS-external-LSAs in its database. OspfExtLsdbLimit MUST be set identically in all routers attached to the OSPF backbone and/or any regular OSPF area. (i.e., OSPF stub areas and NSSAs are excluded). |
| MulticastExtensions |
| 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. |
| ExitOverflowInterval |
| The number of seconds that, after entering OverflowState, a router will attempt to leave OverflowState. This allows the router to again originate non-default AS-external-LSAs. When set to 0, the router will not leave Overflow- State until restarted. |
| DemandExtensions |
| The router's support for demand routing. Enumerations: |
