How are routing updates and Point-to-Point Protocol (PPP) / High-Level Data Link Control (HDLC) keepalives processed when a service policy is applied?
A. Cisco IOS routers use the following two mechanisms to prioritize control packets: • IP precedence • pak_priority Both mechanisms are designed to ensure that key control packets are not dropped or are dropped last by the router and the queuing system when an outbound interface is congested. For more information, refer to Understanding How Routing Updates and Control Packets Are Queued on an Interface with a QoS Service Policy.
