working-path
Syntax working-path path-name
no working-path
Context config>router>gmpls>lsp
Description
This command specifies the working path for a GMPLS LSP. One working path must be specified for
each GMPLS LSP. The path-name parameter must correspond to a path defined under
config>router>gmpls>path.
The no form of the command removes the working-path definition.
Default no working-path
Parameters
path-name — Specifies the name of the path used by the working path.
bandwidth
Syntax bandwidth signal-type signal-type
no bandwidth
Context config>router>gmpls>lsp>working-path
Description This command specifies the bandwidth to be signaled for the path of the GMPLS LSP. Bandwidth is
specified in terms of the RFC 3471 signal type name.
If an empty path is configured or the first hop TE Link is not configured, the system will
automatically select a TE Link to use for a GMPLS LSP path based on the lowest available TE Link
ID with a matching bandwidth (if a bandwidth is configured for the GMPLS LSP). During a data-
bearer link allocation request, an RSVP-requested GMPLS LSP BW can be either a non-zero value as
per RFC 3471 signal-type, or it can be zero). Note that empty paths are not supported in Release 13.0.
There are the following cases:
The no form of the command udates the bandwidth to zero.
Default 0

Values 32 characters maximum text string
• Case 1 — The requested BW is non-zero as per RFC 3471 Signal-type config:
a) When a TE (or TE/DB) Link is configured in the related hop, LMP checks whether the related
port BW is the same (exact match) as the requested BW, and allocates the port (provided any
other checks are OK).
b) When the related Hop is empty: LMP finds a db-link port to the peer node matching the
requested BW, and allocates it.
• Case 2 — Requested BW is zero:
a) When a TE (or TE/DB) Link is configured in the related hop, LMP allocates the port (provided
the other checks are OK), and provides the port BW to RSVP to use in signaling.
b) When the related Hop is empty, LMP finds the first available db-link to the peer (based on
lower db-link Id), and allocates it and provides the port BW to RSVP to use in signaling.
