I want to implement Qos on a GRE tunnel and want to give priority to a destination IP 18.104.22.168 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 22.214.171.124
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 126.96.36.199 ?
If it is possible, how will I test if everything is working fine after configuration?
