Hey All,

I have a couple of 877's that are joined via a stock standard GRE tunnel, they are exchanging routes using OSPF, problem is that if the intenret connection is saturated then OSPF packets seem to get dropped. this causes routes to be droped etc etc. Is there a way I can use QOS of give Priority to OSPF packets to ensure they are always forwarded.

As a little side note is is possible ot give priority to RDP traffic as well?

These router are using std ADSL.

Cheers!

I don't think so.  You can prioritize them within the tunnel, but not outside the tunnel.  Outside the tunnel all traffic will appear the same, GRE and will be treated equally.

I thought that "qos pre-classify" was intended to negate the problem. Is it not possible to use this command to force QOS to look inside the GRE, or even classify it before its encapsulated?

I may be wrong, you can read:

http://www.cisco.com/en/US/tech/tk543/tk545/technologies_tech_note09186a008017405e.shtml#qoscomm

and see how that may work.

However, even with that, the QOS value is only good up to the 1st router you control.  Once it hits the 1st router that you do not own (such your ISP's), everything is treated equal.  

So if SITE1 is sending out packets to SITE2 and SITE2 is saturated, the packets will still be delayed, or even dropped, somewhere within the Internet.  The only way this would help is if it is SITE1 that is saturating the link to SITE2.

In the world of WAN, QoS is a pretty important topic for most, if not all, networks. Some WAN technologies have QoS mechanisms built in, but others, such as some L2 WAN's, don't have QoS control in the provider cloud.
