show isis database

---

Displays information the IS-IS routing database.

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

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

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

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

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

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

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

Use the detail keyword to display the detailed information about the specified LSP(s).

Factory Default: None.

Command Mode: Executive and privileged.

Example 1: The following example shows output of the show isis database level-1 command; first with hostname dynamic disabled, second with it enabled:

router#show isis database level-1 ISIS Level-1 Link State Database LSPID LSP Seq Num LSP Checksum LSP Holdtime ATT/P/OL 1000.5000.0001.00-00 0x0000000e 0xb8be 1200 0/0/0 1000.5000.0002.00-00 0x0000052f 0xd8e7 1199 0/0/0 1000.5000.0003.00-00 0x0000001e 0x8c80 507 0/0/0 . . .

The following table describes the fields in the display:

Table 3-2. Fields Displayed by show isis database  

Field	Description
(Password)	The password or authentication digest, if any exists.
LSPID	The identifier for the link-state packet (LSP).
LSP Seq Num	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.
LSP Checksum	The checksum of the LSP. If the ignore-lsp-error command has been entered, LSPs with incorrect checksums are discarded.
LSP Holdtime	The remaining time, in seconds, that this LSP is valid.
ATT/P/OL	ATT - A 1 indicates the router that originated this LSP is attached through a Level 2 router to at least one other area. P- A 1 indicates the router that originated this LSP has partition repair capability. OL- A 1 indicates the router that originated this LSP is overloaded. This LSP should not be used.

Example 2: The following is sample output of the show isis database detail command:
