LSP Commands
lsp
Syntax [no] lsp lsp-name [bypass-only| mpls-tp src-tunnel-num]
Context config>router>mpls
Description This command creates an LSP that is signaled dynamically by the 7210 SAS M.
When the LSP is created, the egress router must be specified using the to command and at least one
primary or secondary path must be specified. All other statements under the LSP hierarchy are
optional. Notre that the maximum number of static configurable LSPs is 4.
LSPs are created in the administratively down (shutdown) state.
The no form of this command deletes the LSP. All configuration information associated with this LSP
is lost. The LSP must be administratively shutdown before it can be deleted.
Default none
Parameters lsp-name — Name that identifies the LSP. The LSP name can be up to 32 characters long and must be
unique.
bypass-only — Defines an LSP as a manual bypass LSP exclusively. When a path message for a new
LSP requests bypass protection, the PLR first checks if a manual bypass tunnel satisfying the
path constraints exists. If one if found, the 7210 selects it. If no manual bypass tunnel is found,
the 7210 dynamically signals a bypass LSP in the default behavior. The CLI for this feature
includes a knob that provides the user with the option to disable dynamic bypass creation on a
per node basis.
mpls-tp src-tunnel-num — Defines an LSP as an MPLS-TP LSP. The src-tunnel-num is a mandatory
create time parameter for mpls-tp LSPs, and has to be assigned by the user based on the configured
range of tunnel IDs. The following parameters can only be used with an MPLS-TP LSP: to, dest-
global-id, dest-tunnel-number, working-tp-path, protect-tp-path. Other parameters defined for the
above LSP types cannot be used. This is supported on 7210 SAS-T network mode and 7210 SAS-R6
devices.
adaptive
Syntax [no] adaptive
Context config>router>mpls>lsp
Description This command enables the make-before-break functionality for an LSP or LSP path. When enabled
for the LSP, make-before-break will be performed for primary path and all the secondary paths of the
LSP.
Default adaptive
