• Question 174:

  In MPLS QoS , traffic policies are developed on simple traffic classified and complex traffic classification policies based on simple traffic classification the service class color, and drop priority of packet are reset based on the packet in the traffic policies on complex traffic classification measures such as traffic classification is applied on border routers in Different domain, and traffic classification core routers. QoS policies are configured by performing the following operations:

  Defines DiffSer domain and configuring a traffic policy. Classification traffic Defines traffic behavior and configures characteristics of behaviors. Defines a traffic policy and specifies for traffic categories Applies the traffic policy Configure L-LSP Configures reserve address checks Adds interface to the DiffSer domain
