MPLS and RSVP
Note that the lsp-num must match the value configured in the LER for a given path. If no explicit
lsp-num is configured, then working-path or protect-path must be specified (equating to 1 or 2 in
the system).
The forward path must be configured before the reverse path. The configuration of the reverse
path is optional.
The LSP-ID (path-id) parameters apply with respect to the downstream direction of the forward
LSP path, and are used to populate the MIP ID for the path at this LSR.
The reverse path configuration must be deleted before the forward path.
The forward-path (and reverse-path if applicable) parameters can be configured with or without
the path-id, but they must be configured if MPLS-TP OAM is to be able to identify the LSR MIP.
The transit-path can be no shutdown (as long as the forward-path/reverse-path parameters have
been configured properly) with or without identifiers.
The path-id and path-name must be unique on the node. There is a one to one mapping between a
given path-name and path-id.
Traffic can not pass through the transit-path if the transit-path is in the shutdown state.
