Edit OSPF General
| Item | Description |
|
| 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 inter- face; 'disabled' disables it on all inter- faces. |
| VersionNumber | The mandatory version number of the OSPF proto- col is 2. |
| AreaBdrRtrStatus | A flag to note whether this router is an area border router. |
| ASBdrRtrStatus | A flag to note whether this router is config- ured as an Autonomous System border router. |
| 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 con- tained 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. |
| OriginateNewLsas | The number of new link-state advertisements that have been originated. This number is in- cremented each time the router originates a new LSA. |
| RxNewLsas | The number of link-state advertisements re- ceived determined to be new instantiations. This number does not include newer instantia- tions of self-originated link-state advertise- ments. |
| 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. |
| 10MbpsPortDefaultMetric | Used to indicate the cost associated with 10Meg Interface(Port). |
| 100MbpsPortDefaultMetric | Used to indicate the cost associated with 100Meg Interface(Port). |
| 1000MbpsPortDefaultMetric | Used to indicate the cost associated with 1000Meg Interface(Port). |
| TrapEnable | Used to indicate whether Ospf Traps should be sent. |
| AutoVirtLinkEnable | Used to indicate whether auto virtual link creation is enabled or not. If set to true OSPF will create virtual links between ABRs whether it is needed or not, but adjacency will established only when one of the ABR losses connection to backbone area. If set to false then it is user resposibity to create virtual link whenever needed. |
| SpfHoldDownTime | The SPF Hold Down Timer value. The SPF will run at most once per hold down timer value. |
| LastSpfRun | Used to indicate the time(SysUpTime) since the last spf calculated by OSPF. |
