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. |
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: |
