I am setting up QoS for VoIP on several routers. I have two questions:
1) For PPP multilink interfaces, do I apply the service-policy on the multilink interface or on each of the serial interfaces that are a member of that ppp multilink group?
2) For routers that have sub-interfaces, i.e. router on a stick, is the service policy applied to the physical interface, i.e. f0/0 or the sub-interfaces,i.e. f0/0.5 & f0/0.6?
Thanks in advance for your assistance in this matter!
