Description
Configure the setup priority and reservation priority for an LSP. If insufficient link bandwidth is available during session establishment, the setup priority is compared with other setup priorities for established sessions on the link to determine whether some of them should be preempted to accommodate the new session. Sessions with lower hold priorities are preempted.
Options
reservation-priority—Reservation priority, used to keep a reservation after
it has been set up. A smaller number has a higher priority. The priority
must be greater than or equal to the setup priority to prevent preemption
loops.
Range: 0 through 7, where 0 is the highest and 7 is the lowest priority.
Default: 0 (Once the session is set up, no other session can preempt it.)
setup-priority—Setup priority.
Range: 0 through 7, where 0 is the highest and 7 is the lowest priority.
Default: 7 (The session cannot preempt any existing sessions.)
Required Privilege Level
