If the tunnel is setup over interface, bandwidth assigned to tunnel is taken out from bandwidth available on that interface. But this is purely control plane reservation. Nothing will be enforced in data plane.</div><div class=""><br class=""></div><div class="">To enforce those values, you need to apply QoS policies to interfaces over which you expert to serve MPLS TE tunnels.</div><div class=""><br class=""></div><div class="">— </div><div class="">./</div></body></html>
