tunnel mpls bandwidth
Syntax
tunnel mpls [ traffic-eng ] bandwidth bandwidth
no tunnel mpls [ traffic-eng ] bandwidth
Release Information
Command introduced before JUNOSe Release 7.1.0.
Description
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.
Options
