I have a DMVPN setup and on the spoke router the tunnel interface is T0 and it's on FE0/0 where the ISP router is connected. The total bandwidth is 1.5Mbps.
I have IP phone traffic on the VPN tunnel and I want to prioritize it. However the local internet traffic goes directly out of FE0/0, not through the tunnel. How can I setup the QoS so the phone traffic on the vpn tunnel will have priority and guaranteed bandwidth while the internet traffic will still be able to fully utilize the 1.5 link when there is no phone traffic? Thanks!
