Release Information

Statement introduced before JUNOS Release 7.4.

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.)

Usage Guidelines

See Configuring Priority and Preemption for LSPs.
