I'm trying to configure the policy-map for Ethernet interface of the router.
and I wonder if I should define the class for controling traffic(like RoutingProtocol,HSRP,GRE-keepalive etc) in this policy.
I found a document says that total amount of bandwidth of all class-maps should be under 75% of available bandwidth because the other 25 percent is used for control and routing traffic.
Are these control traffic directed to class-default?
or are they out of control with the QoS process?
(are any packet originated by the router itself same?)
or should I prepare a dedicated class-map for them?
