I have configured two IPIP VPN tunnels from the main office to the branch offices. I would like to apply QOS for specific traffic and when I go in to the Tunnel interface to apply the QOS Pre-classify command I couldn't find it.
I am aware that this command is a must to mark the packets for QOS before routing through the tunnel. I believe my IOS doesn't support this. I read through lots of documents regarding QOS and it says this command is supported in all the IOS release after 12.3.
I am not sure whether I am missing something.
So I am just wondering do I need to buy a different IOS. If YES then how shall I buy it.
If any of you have got a IOS that supports QOS-PRECLASSFIY command will you be able to send it across to me.
I have already spent a lot of time and it is getting really important.
Your help will be highly appreciated.
Below is the IOS version on the Cisco 828 router:
Cisco Internetwork Operating System Software
IOS (tm) C828 Software (C828-K9OSY6-M), Version 12.3(10a), RELEASE SOFTWARE (fc2
One way is to bypass the use of Pre-Classification itself. On the ingress LAN you can mark the packets with TOS or DSCP and match the same on the tunnel as the ToS byte s copied by default to the GRE header. Hence you dont need Pre classification at all. Let me know if you need any help with the config
