QoS IPSec Inside GRE Multiple Tunnels

We are deploying QoS at a hub location. Multiple GRE tunnels are terminating there. Each site 3 t1's in a multilink bundle. I want each sie to be guaranteed a t1 of bandwidth but have the ability to use all 3 T1' if there is no other traffic. See partial config below. Will this approach work? The carrier will be providing inbound QoS.

Re: QoS IPSec Inside GRE Multiple Tunnels

Hello Steve,

This will shape the tunnels to 1536. However, it will not allow the tunnels to use more bandwidth if available.
