OSPF link-state database (external)

OSPF link-state database (external)
The following table is identical to the OSPF LSDB table in format, but contains only external
link-state advertisements. The purpose is to allow external LSAs to be displayed once for the router
rather than once in each non-stub area.
snOspfLsdbAdvertisemen
t
brcdIp.1.2.4.9.1.1.9
Syntax: OCTET STRING
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
Name, OID, and syntax Access Description
Name, OID, and syntax Access Description
snOspfExtLsdbTable
brcdIp.1.2.4.10.1
None The link-state external database table.
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.
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.
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.
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
more negative.
snOspfExtLsdbSequence
brcdIp.1.2.4.10.1.1.5
Syntax: Integer32
Read-only Shows the sequence number of this entry. The OSPF neighbor that
sent the LSA stamps it 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.
snOspfExtLsdbAge
brcdIp.1.2.4.10.1.1.6
Syntax: Integer32
Read-only Shows the age of the link-state advertisement in seconds.
