I want to implement Qos on a GRE tunnel and want to give priority to a destination IP 220.127.116.11 of a system from our site using WAN link. I will match the traffic through an ACL in class-map in which source IP will be any and destination IP will be 18.104.22.168
I have following questions:
Can I apply service-policy on a tunnel interface?
Will routers including ISP and ours through out the network to destination will give priority to the packets with destination of IP 22.214.171.124 ?
If it is possible, how will I test if everything is working fine after configuration?
