i just formed a GRE VPN tunnel between two 1841 routers, which established on FastEthernet Subinterface (F0/1.1) at both. And want to apply an Qos control to classify some important traffic.
What i want to know is - Where should i apply the "service-policy" config?
1. physical interface (F0/1) and then apply "qos pre-classify" on tunnel?
2. sub-interface (F0/1.1) and then apply "qos pre-classify" on tunnel?
