The no form of the command resets the path-preference value to its default.
Default 255
Parameters preference-number — specifies a priority value for a standby secondary LSP path; the
lower the value, the higher the priority.
Values 1 to 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
