OSPF link-state database
OSPF link-state database
The link-state database contains the link-state advertisement from all the areas to which the
device is attached.
Reference: RFC 1583 “OSPF Version 2”, section 12 Link State Advertisements.
Name, OID, and Syntax Access Description
snOspfLsdbTable
brcdIp.1.2.4.9.1 None The OSPF Process’s link-state database.
snOspfLsdbEntry
brcdIp.1.2.4.9.1.1 None An entry in the OSPF Process’s link-state database. Each entry
represents a single link-state advertisement.
snOspfLsdbEntryIndex
brcdIp.1.2.4.9.1.1.1
Syntax: Integer32 Read only The ID of the entry in the link-state database.
snOspfLsdbAreaId
brcdIp.1.2.4.9.1.1.2
Syntax: AreaID Read only Shows the Area from which the LSA was received. The value is in a
32-bit format.
Reference: RFC 1583 “OSPF Version 2”, section C.2 Area parameters
snOspfLsdbType
brcdIp.1.2.4.9.1.1.3
Syntax: Integer Read only Specifies the type of the link-state advertisement. Each link-state type
has a separate advertisement format.
•
routerLink(1)
•
networkLink(2)
•
summaryLink(3)
•
asSummaryLink(4)
Reference: RFC 1583 “OSPF Version 2”, section A.4.1 The Link State
Advertisement header
snOspfLsdbLsId
brcdIp.1.2.4.9.1.1.4
Syntax: IpAddress Read only Specifies the link-state ID. This 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.
Reference: RFC 1583 “OSPF Version 2”, section 12.1.4 Link State ID
snOspfLsdbRouterId
brcdIp.1.2.4.9.1.1.5
Syntax: RouterID Read only Identifies the originating router in the Autonomous System. This
information is in a 32-bit number. The format is determined by the
“snOspfLsdbAreaIdFormat” object.
Reference: RFC 1583 “OSPF Version 2”, section C.1 Global
parameters
NOTE: OSPF Sequence Number is a 32-bit signed 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.
snOspfLsdbSequence
brcdIp.1.2.4.9.1.1.6
Syntax: Integer32 Read only Shows the sequence number of this entry. The OSPF neighbor that
sent the LSA stamps the LSA with a sequence number to enable the
Layer 3 Switch and other OSPF routers to determine which LSA for a
given route is the most recent. This object can be used to detect old
and duplicate link-state advertisements. The higher the sequence
number, the more recent the advertisement.
Reference: RFC 1583 “OSPF Version 2”, section 12.1.6 LS sequence
number
snOspfLsdbAge
brcdIp.1.2.4.9.1.1.7
Syntax: Integer32 Read only Shows the age of the link-state advertisement in seconds.
Reference: RFC 1583 “OSPF Version 2”, section 12.1.1 LS age
