Command Modes LSP Attributes configuration (config-lsp-attr)
Command History
Usage Guidelines Use this command to configure setup and hold priority for an LSP in an LSP attribute list. Setup priority
an
d hold priority are typically configured to be equal, and setup priority cannot be better (numerically
smaller) than the hold priority.
To associate the LSP priority attribute and the LSP attribute list with a path option for an LSP, you must
co
nfigure the tunnel mpls traffic-eng path option command with the attributes string keyword and
argument, where string is the identifier for the specific LSP attribute list.
Examples The following example shows how to set the LSP hold and setup property to 0 in an LSP attribute list
id
entified by the string hipriority:
configure terminal
!
mpls traffic-eng lsp attributes hipriority
priority 0 0
exit
end
setup-priority Priority used when signaling an LSP to determine which existing LSPs can
be preempted. Valid values are from 0 to 7, where a lower number indicates
a higher priority. Therefore, an LSP with a setup priority of 0 can preempt
any LSP with a non-0 priority.
hold-priority (Optional) Priority associated with an LSP to determine if it should be
pr
eempted by other LSPs that are being signaled. Valid values are from 0 to
7, where a lower number indicates a higher priority.
