show isis database extensive

---

Displays extensive TLV link state database information for this router.

Syntax: show isis database extensive [l1 | level-1 | l2 | level-2] [LSPID | hostname | hostname.nn-nn]

l1 or level-1	Display extensive routing information for Level-1 LSPs only.
l2 or level-2	Display extensive routing information for Level-2 LSPs only.
LSPID	Display extensive routing information for the specified LSP. Enter LSPID in dotted decimal format: nnnn.nnnn.nnnn.nn-nn
hostname	Specifies the hostname for the detailed display of extensive routing information for all LSPs.
hostname.nn-nn	When hostname dynamic is enabled, display extensive routing information for the specified LSP. Enter the LSP ID as <hostname>.nn-nn

Description: Use the show isis database extensive command with no arguments to display summarized extensive information about both Level-1 and Level-2 LSPs.

Use the show isis database extensive l1 or show isis database extensive level-1 command to display summarized extensive information about Level-1 LSPs.

Use the show isis database extensive l2 or show isis database extensive level-2 command to display summarized extensive information about Level-2 LSPs.

Use the show isis database extensive nnnn.nnnn.nnnn.nn-nn command to display detailed extensive information about the specified LSP.

Use the show isis database extensive hostname.nn-nn command to display detailed extensive information about the specified LSP when hostname dynamic is enabled.

Factory Default: None.

Command Mode: Executive and privileged.

Example 1: The following example shows output of the show isis database extensive level-1 command:

The following table describes the fields in the display:

Table 3-4. Fields Displayed by show isis database  

Field	Description
Sequence	The sequence number for the LSP. Every time a LSP is updated, the sequence number is incremented so that a router can determine if the LSP it has just received is indeed newer than one it already has in its database.
Checksum	Checksum value computed on the entire packet header. If the ignore-lsp-error command has been entered, LSPs with incorrect checksums are discarded.
Lifetime	Total lifetime of the packet.
LSPID	The identifier for the link-state packet (LSP).
Length	Packet Length in octets.
Allocated Length	Actual Allocated packet length in octets.
Router ID
Remaining Lifetime	Remaining lifetime of the Packet
Level	Specifies whether Level-1 or Level-2.
Aging Timer expires in
Protocols	Protocol for this packet.
Attributes	0x01 = Level-1, 0x02 = Level-2
NLPID	Network Layer Protocol ID
Fixed Length
Version
Sysid Length
Packet Type
Packet Version
Max Area	The maximum number of areas configurable for this NET.
Metric	Metric value and type for this prefix.

Example 2: The following is sample output of the show isis database extensive level-2 command:

router#show isis database extensive level-2 IS-1#show isis database extensive level-2 ISIS Level-2 Link State Database IS-1.00-00 Sequence: 0x00000199, Checksum: 0x9606, Lifetime: 460 secs Header: LSP ID: IS-1.00-00, Length: 48 bytes Allocated length: 48, Router ID: 4.4.4.4 Remaining Lifetime: 460 secs, Level: 2, Interface: NULL Aging timer expires in: 460 secs Protocols: IP Packet: LSP_ID: IS-1.00-00, Length: 48 bytes, Lifetime: 460 secs Checksum: 0x9606, Sequence: 0x00000199, Attributes: 0x2 <L2> NLPID: 0x83, Fixed Length: 27 bytes, Version: 1, Sysid Length : 0 Bytes Packet Type: 20, Packet Version: 1, Max Area: 3 TLVs: Area Address: 49.0001 NLPID: 0xCC Router ID: 4.4.4.4 Hostname: IS-1 No queued transmissions . . . router#
