specifies to exclude a bitmap that lists the admin groups that should be included during the CSPF computation
the total number of hops an FRR bypass or detour LSP can take before merging back onto the main LSP path

the percentage difference below which two links are considered equal for least-fill bandwidth comparison. When comparing the percentages of least available link bandwidth across available paths, whenever two percentages differ by less than the value configured as the least-fill minimum threshold, CSPF considers them to be equal and applies a random number generator to select the path.
resignal {lsp lsp-name path path-name | delay minutes}
tools>perform>router>mpls
This command resignals specified LSP paths. The minutes parameter is used to configure the global timer to resignal all LSPs. The resignal timer is the time before resignaling occurs after the resignal condition occurs. If only lsp-name and path-name are provided, the specified LSP is resignaled immediately. For the delay option to work, the resignal time in the config>router>mpls context must be set.
n/a
specifies a unique LSP name, up to 32 characters
specifies the name for the LSP path, up to 32 characters
specifies the delay interval, in minutes, before all LSPs are resignaled. If the value 0 is entered, all LSPs are resignaled immediately.
resignal-bypass delay minutes
resignal-bypass lsp bypass-lsp-name [force]
tools>perform>router>mpls
This command performs a manual reoptimization of a specific dynamic or manual bypass LSP or of all dynamic bypass LSPs.
The manual bypass LSP name is user-configured. The dynamic bypass LSP name is shown in the output of the show>router>mpls>bypass-tunnel dynamic detail command.
The delay option triggers the global reoptimization of all dynamic bypass LSPs at the expiry of the specified delay. This option forces the global bypass resignal timer to expire after an amount of time equal to the value of the delay parameter. This option does not apply to a manual bypass LSP.
When a bypass LSP name is specified, that dynamic or manual bypass LSP is not signaled and the associations are not evaluated even if the new bypass LSP path has the same cost as the current one. This is a different behavior from the resignal command for the primary or secondary path of an LSP, because a bypass LSP can have a large number of PSB associations.
If the specified LSP is a manual bypass LSP with no PSB associations, the LSP is torn down and resignaled using the new path provided by CSPF. If there are one or more PSB associations but the PLR is not active, the command fails and the user is asked to explicitly enter the force option. In this case, the manual bypass LSP is torn down and resignaled, leaving the associated LSP primary paths temporarily unprotected. If there are any active PLRs associated with the manual bypass LSP, the command fails

sr-te-cspf to ip-address [path path-name] [from ip-address]
tools>perform>router>mpls
This command computes and returns the segment routing label stack for any user-specified MPLS path to a destination router.
MPLS passes the specified path information to the TE-DB, which converts the list of hops into a label stack by scanning the database for adjacency and node SID information that belongs to the router or link identified by each hop address. If the conversion is successful, the database will return the actual selected hop SIDs plus labels, as well as the configured path hop addresses that were used as the input for this conversion.
specifies the destination IP address
specifies the path name
specifies the originating IP address
trap-suppress number-of-traps time-interval
tools>perform>router>mpls
This command modifies thresholds for trap suppression. The command is used to suppress traps after the specified number of traps has been raised within the specified period of time.
n/a
specifies the number of traps in multiples of 100. An error message is generated if an invalid value is entered.
specifies the time interval in seconds
update-path {lsp lsp-name path current-path-name new-path new-path-name}
tools>perform>router>mpls
This command instructs MPLS to replace the path of a primary or secondary LSP. The primary or secondary LSP path is indirectly identified with the current-path-name value. The same path name cannot be used more than once for an LSP name.
This command applies to both a CSPF LSP and a non-CSPF LSP. The command only works when the specified current-path-name has the adaptive option enabled. The adaptive option can be enabled at the LSP level or the path level.
The new path must have been configured in the CLI or provided via SNMP. The CLI command for entering the path is config>router>mpls>path path-name.
The command fails if any of the following conditions exist:
the specified current-path-name of this LSP does not have the adaptive option enabled
the specified new-path-name value does not correspond to a previously defined path
the specified new-path-name value exists but is being used by any path of the same LSP, including this one
When you execute this command, MPLS performs the following procedures.
MPLS performs a single MBB attempt to move the LSP path to the new path.
If the MBB is successful, MPLS updates the new path.
MPLS writes the corresponding NHLFE in the data path if this path is the current backup path for the primary path.
If the current path is the active LSP path, MPLS will update the path and write the new NHLFE in the data path, which will cause traffic to switch to the new path.
If the MBB is not successful, the path retains its current value.
The update-path MBB has the same priority as the manual resignal MBB.

n/a
ldp-sync-exit
tools>perform>router>ospf

This command terminates IGP-LDP synchronization. OSPF or IS-IS then advertises the actual cost value of the link for all interfaces that have IGP-LDP synchronization enabled, if the currently advertised cost is different.
