DMVPN QOS

[CSCO10456946]

hi,

I need to built a qos over DMVPN.I have a 3725 and tunnel source of DMVPN tunnel is a serial. I ty to mark my interested packets with ip precedence when they are entering on lan interface, apply qos pre-clasified on tunnel interface, and after that I make a policy to aplly on serial wich is source of tunnel.

This policy need to match ip precedence what I marked on Lan interface but seems that qos preclasified applied on tunnel don't work because my policy don't match policy that I set before!

Any ideea?

You will have to use the qos pre-classify command as shown below to the tunnel interface.

interface Tunnel0

qos pre-classify

TOS should be copied automatically to the outer IP header both with GRE and IPSec, so pre-classify is not needed, but use 12.2(13)T at least due to software bugs.
