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.
