CISCOSB-OSPF-MIB Table View

OSPF Instance General Variables

Information describing the configured parameters and
cumulative statistics of the router's attached areas.
The interfaces and virtual links are configured
as part of these areas.  Area 0.0.0.0, by definition,
is the backbone area.

The set of metrics that will be advertised
by a default Area Border Router into a stub area.

The OSPF Process's link state database (LSDB).
The LSDB contains the link state advertisements
from throughout the areas that the device is attached to.

The Address Range Table acts as an adjunct to the Area
Table.  It describes those Address Range Summaries that
are configured to be propagated from an Area to reduce
the amount of information about it that is known beyond
its borders.  It contains a set of IP address ranges
specified by an IP address/IP network mask pair.
For example, class B address range of X.X.X.X
with a network mask of 255.255.0.0 includes all IP
addresses from X.X.0.0 to X.X.255.255.
          
Note that this table is obsoleted and is replaced
by the Area Aggregate Table.

The Host/Metric Table indicates what hosts are directly
attached to the router, what metrics and types
of service should be advertised for them,
and what areas they are found within.

The OSPF Interface Table describes the interfaces
from the viewpoint of OSPF.
It augments the ipAddrTable with OSPF specific information.

The Metric Table describes the metrics to be advertised
for a specified interface at the various types of service.
As such, this table is an adjunct of the OSPF Interface
Table.
          
Types of service, as defined by RFC 791, have the ability
to request low delay, high bandwidth, or reliable linkage.
          
For the purposes of this specification, the measure of
bandwidth:
          
Metric = referenceBandwidth / ifSpeed
          
is the default value.
The default reference bandwidth is 10^8.
For multiple link interfaces, note that ifSpeed is the sum
of the individual link speeds.  This yields a number having
the following typical values:
          
Network Type/bit rate   Metric
          
>= 100 MBPS                 1
Ethernet/802.3             10
E1                         48
T1 (ESF)                   65
64 KBPS                    1562
56 KBPS                    1785
19.2 KBPS                  5208
9.6 KBPS                   10416
          
Routes that are not specified use the default
(TOS 0) metric.
          
Note that the default reference bandwidth can be configured
using the general group object ospfReferenceBandwidth.

Information about this router's virtual interfaces
that the OSPF Process is configured to carry on.

A table describing all non-virtual neighbors
in the locality of the OSPF router.

This table describes all virtual neighbors.
Since virtual links are configured
in the Virtual Interface Table, this table is read-only.

The Area Aggregate Table acts as an adjunct
to the Area Table.  It describes those address aggregates
that are configured to be propagated from an area.
Its purpose is to reduce the amount of information
that is known beyond an Area's borders.
          
It contains a set of IP address ranges
specified by an IP address/IP network mask pair.
For example, a class B address range of X.X.X.X
with a network mask of 255.255.0.0 includes all IP
addresses from X.X.0.0 to X.X.255.255.
          
Note that if ranges are configured such that one range
subsumes another range (e.g., 10.0.0.0 mask 255.0.0.0
and 10.1.0.0 mask 255.255.0.0),
the most specific match is the preferred one.

The OSPF Process's link-local link state database
for non-virtual links.
This table is identical to the OSPF LSDB Table
in format, but contains only link-local Link State
Advertisements for non-virtual links.  The purpose is
to allow link-local LSAs to be displayed for each
non-virtual interface.  This table is implemented to
support type-9 LSAs that are defined
in 'The OSPF Opaque LSA Option'.

The OSPF Process's link-local link state database
for virtual links.
          
This table is identical to the OSPF LSDB Table
in format, but contains only link-local Link State
Advertisements for virtual links.  The purpose is to
allow link-local LSAs to be displayed for each virtual
interface.  This table is implemented to support type-9 LSAs
