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:
  • enabled (1)
  • disabled (2)
VersionNumber
The current version number of the OSPF protocol is 2.
Enumerations:
  • undef (1)
  • version2 (2)
AreaBdrRtrStatus
A flag to note whether this router is an area border

router.
Enumerations:
  • true (1)
  • false (2)
AsBdrRtrStatus
A flag to note whether this router is an Autonomous

System border router.
Enumerations:
  • true (1)
  • false (2)
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.
TOSSupport
The router's support for type-of-service routing.
Enumerations:
  • true (1)
  • false (2)
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:
  • true (1)
  • false (2)
