display isis lsdb
Use display isis lsdb to display IS-IS LSDB information.
Syntax
display isis lsdb [ [ level-1 | level-2 ] | local | [ lsp-id lspid | lsp-name lspname ] | verbose ] * [ process-id ]

Parameters
level-1: Displays the level-1 LSDB.
level-2: Displays the level-2 LSDB.
local: Displays LSP information generated locally.
lsp-id lspid: Specifies an LSP ID, in the form of sysID. Pseudo ID-fragment num, where sysID represents the originating node or pseudo node. Pseudo ID is separated by a dot from sysID and by a hyphen from fragment num.
lsp-name lspname: Specifies the LSP name, in the form of Symbolic name.Pseudo ID-fragment num, where Pseudo ID is separated by a dot from Symbolic name and by a hyphen from fragment num. If the Pseudo ID is 0, specify the LSP name in the form Symbolic name-fragment num.
verbose: Displays LSDB detailed information. If you do not specify this keyword, the command displays brief information about LSDB.
process-id: Specifies an IS-IS process by its ID in the range of 1 to 65535. If you do not specify this argument, the command displays LSDBs for all IS-IS processes.
Usage guidelines
If no level is specified, the command displays both Level-1 and Level-2 LSDB information.
