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 indexes of the table are ospfLsdbAreaId, ospfLsdbType, ospfLsdbLsid, ospfLsdbRouterId.

Implemented Specifications |
|---|---|---|---|---|---|
|
1.3.6.1.2.1.14.4.1.1 |
ospfLsdbAreaId |
IpAddress |
read-only |
The 32-bit identifier of the area from which the LSA was received. |
The actually supported access is read-only. |
|
1.3.6.1.2.1.14.4.1.2 |
ospfLsdbType |
INTEGER{routerLink(1),networkLink(2),summaryLink(3),asSummaryLink(4),asExternalLink(5),multicastLink(6),nssaExternalLink(7),areaOpaqueLink(10)} |
read-only |
The type of the link state advertisement. Each link state type has a separate advertisement format. Note: External link state advertisements are permitted for backward compatibility, but should be displayed in the ospfAsLsdbTable rather than here. |
The actually supported access is read-only. |
|
1.3.6.1.2.1.14.4.1.3 |
ospfLsdbLsid |
IpAddress |
read-only |
The Link State ID is an LS Type Specific field containing either a Router ID or an IP address; it identifies the piece of the routing domain that is being described by the advertisement. |
The actually supported access is read-only. |
|
1.3.6.1.2.1.14.4.1.4 |
ospfLsdbRouterId |
IpAddress |
read-only |
The 32-bit number that uniquely identifies the originating router in the Autonomous System. |
The actually supported access is read-only. |
|
1.3.6.1.2.1.14.4.1.5 |
ospfLsdbSequence |
Integer32 |
read-only |
The sequence number field is a signed 32-bit integer. It starts with the value '80000001'h, or -'7FFFFFFF'h, and increments until '7FFFFFFF'h. Thus, a typical sequence number will be very negative. It is used to detect old and duplicate Link State Advertisements. The space of sequence numbers is linearly ordered. The larger the sequence number, the more recent the advertisement. |
This object is implemented as defined in the corresponding MIB files. |
|
1.3.6.1.2.1.14.4.1.6 |
ospfLsdbAge |
Integer32 |
read-only |
This field is the age of the link state advertisement in seconds. |
This object is implemented as defined in the corresponding MIB files. |
|
1.3.6.1.2.1.14.4.1.7 |
ospfLsdbChecksum |
Integer32 |
read-only |
This field is the checksum of the complete contents of the advertisement, excepting the age field. The age field is excepted so that an advertisement's age can be incremented without updating the checksum. The checksum used is the same that is used for ISO connectionless datagrams; it is commonly referred to as the Fletcher checksum. |
This object is implemented as defined in the corresponding MIB files. |
|
1.3.6.1.2.1.14.4.1.8 |
ospfLsdbAdvertisement |
OCTET STRING{(1,65535)} |
read-only |
The entire link state advertisement, including its header. Note that for variable length LSAs, SNMP agents may not be able to return the largest string size. |
Only support 1000. |
