Oliver,
Check into the "qos preclassify" command, along with CBWFQ. Not only is
this the preferred method, but the command is not supported when using
legacy priority queuing. By default, the IP header (TOS/DSCP) is copied
into the GRE header, and then copied into the IPSec header. If this
application is JUST for voice, you won't need this command. If you need
to prioritize anything OTHER then ToS/DSCP, i.e. TCP/UDP port numbers
via ACLs, then this command is needed. Check it out.

Subject: Slight offtopic: Create QoS with IPsec and GRE
Hello all
sorry for the offtopic question...
I have a customer with a hub and spoke IPsec/GRE Networks. We have to
use GRE, because we run eigrp to the spokes. On the central site is a
time critical application (SAP) and some other preferred traffic
(smtp/pop). All spokes has a ADSL interface on a small router (830 or
1720) has a to directly to the internet for www and so on.
What is the best way to reserve bandwidth for application X and Y.
Im thinking CBWFQ will fit best, agree?
Does CBWFQ works well with GRE Tunnels?
thanks for any feedback
Oliver
