Root-cause problems for LSP

The following root-cause problem is diagnosed for LSP:

Down:

• For a TE tunnel, the LSP is operationally down because it failed to establish one or more TE LSPs.

• For a TE LSP or subLSP, the LSP is operationally down because one of its LSP hops has failed.

• For an LDP LSP, the LSP is operationally down because the LSP outsegment of the LSP’s source device has failed.
