    tunnel mpls bandwidth


    tunnel mpls [ traffic-eng ] bandwidth bandwidth

    no tunnel mpls [ traffic-eng ] bandwidth

    Release Information

    Command introduced before JunosE Release 7.1.0.


    Specifies the bandwidth required for the tunnel. The no version removes the bandwidth constraint from the tunnel.

    When the bandwidth constraint is configured, MPLS automatically creates and attaches a QoS profile to the tunnel to enforce the bandwidth reservation. The QoS profile creates a scheduler node at the LSP level, with a scheduler profile that has an assured rate corresponding to the reserved bandwidth. The QoS profile also creates queues above the scheduler node so that traffic of a particular class will be subject to the scheduler node. If no queue are created at the LSP level for a particular class, the traffic of that class enters that class's queue at a lower level, bypassing the bandwidth reservation enforcement.


    • traffic-eng—Specifies optional keyword for compatibility with non–E Series implementations
    • bandwidth—Amount of bandwidth required for the tunnel in kilobits per second, in the range 0–4294967295; default value is 0
