OSPF link-state database

OSPF link-state database

The OSPF 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.

NOTE

The following table is not supported on the Brocade MLXe router, Brocade NetIron XMR, Brocade
NetIron MLX, Brocade NetIron CES, and Brocade NetIron CER series devices.

Name, OID, and syntax

Access

Description

snOspfLsdbTable
brcdIp.1.2.4.9.1

None

The OSPF process’s link-state database.

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.

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)

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.

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.

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 more
negative than a negative number.

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.

snOspfLsdbAge
brcdIp.1.2.4.9.1.1.7
Syntax: Integer32

Read-only

Shows the age of the link-state advertisement in seconds.

snOspfLsdbChecksum
brcdIp.1.2.4.9.1.1.8
Syntax: Integer32

Read-only

Indicates the checksum for the LSA packet. The checksum is based on
all the fields in the packet except the age field. The Layer 3 Switch
uses the checksum to verify that the packet is not corrupted.
