display isis lsdb

Function

The display isis lsdb command displays the LSDB information of IS-IS.

Format

display isis process-id lsdb [ { level-1 | level-2 } | verbose | { local | lsp-id | is-name symbolic-name } ] ^*

display isis lsdb [ { level-1 | level-2 } | verbose | { local | lsp-id | is-name symbolic-name } ] ^* [ process-id | vpn-instance vpn-instance-name ]

Parameters

Parameter	Description	Value
process-id	Specifies the IS-IS process ID.	The value is an integer ranging from 1 to 65535.
level-1	Indicates the LSDB of Level-1.	-
level-2	Indicates the LSDB of Level-2.	-
verbose	Displays detailed information about the LSDB. You can specify verbose to view the details of the IS-IS LSDB, including the MT ID, MT neighbor ID, and IPv6 prefix.	-
local	Displays the local database.	-
lsp-id	Specifies the LSP ID.	It is in dotted decimal notation. The value is ranging from 16 to 20 and in the form of ####.####.####.##-##, such as 0050.0500.5004.00-00.
is-name symbolic-name	Specifies the dynamic hostname in the form of is-name or is-name.##-## (##-## refers to pseudonode ID and LSP fragment ID).	It is a string ranging from 1 to 64 if it is "is-name" or ranging from 1 to 70 if it is "is-name.##-##" .
vpn-instance vpn-instance-name	Displays LSDB information about the multi-instance IS-IS process in the specified VPN instance.	The value is a string of 1 to 31 case-sensitive characters, spaces not supported. When double quotation marks are used around the string, spaces are allowed in the string.
