OSPF link state database, external

OSPF link state database, external

The link-state database contains the link-state advertisement from throughout the areas that the
device is attached to.

This table is identical to the OSPF LSDB Table in format, but contains only external link-state
advertisement. The purpose is to allow external LSAs to be displayed once for the router rather than
once in each non-stub area.

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.
Reference: RFC 1583 “OSPF Version 2”, section 2.1.7 LS checksum

snOspfLsdbAdvertisement
brcdIp.1.2.4.9.1.1.9
Syntax: OctetString

Read only

Shows the data in the link-state advertisement, including its header in
octets.
Reference: RFC 1583 “OSPF Version 2”, section Section 12 Link State
Advertisements

snOspfLsdbAreaIdFormat
brcdIp.1.2.4.9.1.1.10
Syntax: Integer

Read only

Specifies the format of how RouterId will be entered in the

“snOspfLsdbRouterId”

object:

integer(0) – Integer

ipAddress(1) – IP address

snOspfExtLsdbTable
brcdIp.1.2.4.10.1

None

The Link-State External Database Table.
Reference: RFC 1583 “OSPF Version 2”, section Section 12 Link State
Advertisements

snOspfExtLsdbEntry
brcdIp.1.2.4.10.1.1

None

An entry in the Link-State External Database Table. Each entry
represents a single link-state advertisement.

snOspfExtLsdbEntryIndex
brcdIp.1.2.4.10.1.1.1
Syntax: Integer32

Read only

The table entry index of this link-state database.

snOspfExtLsdbType
brcdIp.1.2.4.10.1.1.2
Syntax: Integer

Read only

Shows the type of the link-state advertisement. Each link-state type
has a separate advertisement format.
Reference: RFC 1583 “OSPF Version 2”, section Appendix A.4.1 The
Link State Advertisement header

snOspfExtLsdbLsId
brcdIp.1.2.4.10.1.1.3
Syntax: Integer

Read only

Specifies the external 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

snOspfExtLsdbRouterId
brcdIp.1.2.4.10.1.1.4
Syntax: Integer

Read only

Identifies the originating router in the Autonomous System. This
information is in a 32-bit number.
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. It increments
until ’7FFFFFFF’h Thus, a typical sequence number will be
very negative.
