path-preference
Syntax [no] path-preference value
Context config>router>mpls>lsp>secondary
Description This command enables use of path preference among configured standby secondary paths per LSP. If
all standby secondary paths have a default path-preference value then a non-standby secondary path
remains an active path, while a standby secondary is available. A standby secondary path configured
with highest priority (lowest path-preference value) must be made the active path when the primary is
not in use. Path preference can be configured on standby secondary path.
The no form of this command resets the path-preference to the default value.
Default 255
Parameters value — Specifies an alternate path for the LSP if the primary path is not available.
Values 1–255
record
Syntax [no] record
Context config>router>mpls>lsp>primary
config>router>mpls>lsp>secondary
Description This command enables recording of all the hops that an LSP path traverses. Enabling record
increases the size of the PATH and RESV refresh messages for the LSP since this information is
carried end-to-end along the path of the LSP. The increase in control traffic per LSP may impact
scalability.
The no form of this command disables the recording of all the hops for the given LSP. There are no
restrictions as to when the no command can be used. The no form of this command also disables the
record-label command.
Default record
record-label
Syntax [no] record-label
Context config>router>mpls>lsp>primary
config>router>mpls>lsp>secondary
Description This command enables recording of all the labels at each node that an LSP path traverses. Enabling
the record-label command will also enable the record command if it is not already enabled.
The no form of this command disables the recording of the hops that an LSP path traverses.
Default record-label
