The OSPF Process's external LSA link state database.
This 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.
Note that external LSAs are also in the AS-scope link state database.
The indexes of the table are ospfExtLsdbType, ospfExtLsdbLsid, ospfExtLsdbRouterId.

|---|---|---|---|---|---|
|
1.3.6.1.2.1.14.12.1.1 |
ospfExtLsdbType |
INTEGER{asExternalLink(5)} |
read-only |
The type of the link state advertisement. Each link state type has a separate advertisement format. |
This object is implemented as defined in the corresponding MIB files. |
|
1.3.6.1.2.1.14.12.1.2 |
ospfExtLsdbLsid |
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. |
This object is implemented as defined in the corresponding MIB files. |
|
1.3.6.1.2.1.14.12.1.3 |
ospfExtLsdbRouterId |
IpAddress |
read-only |
The 32-bit number that uniquely identifies the originating router in the Autonomous System. |
This object is implemented as defined in the corresponding MIB files. |
|
1.3.6.1.2.1.14.12.1.4 |
ospfExtLsdbSequence |
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. |
|
1.3.6.1.2.1.14.12.1.5 |
ospfExtLsdbAge |
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. |
|
1.3.6.1.2.1.14.12.1.6 |
ospfExtLsdbChecksum |
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. |
|
1.3.6.1.2.1.14.12.1.7 |
ospfExtLsdbAdvertisement |
OCTET STRING{(36,36)} |
read-only |
The entire link state advertisement, including its header. |
support 1000 length. |
