Configuring CoS with IPv6 DiffServ

You override the default packet forwarding behavior of the router when you configure CoS using IPv6 DiffServ. The three main areas of configuration are classifiers (by default, the router does not classify packets using DiffServ), scheduling (by default, the router only has two queues enabled), and rewrite rules (by default, the router does not rewrite CoS bits).

To implement CoS using IPv6 DiffServ, you must configure the following:

• Configuring a Firewall Filter for an MF Classifier on Customer Interfaces
• Applying the Firewall Filter to Customer Interfaces
• Assigning Forwarding Classes to Output Queues
• Configuring Rewrite Rules
• Applying Rewrite Rules to an Interface
• Configuring BA Classifiers
• Applying a BA Classifier to an Interface
• Configuring RED Drop Profiles
• Configuring Schedulers
• Configuring Scheduler Maps
• Applying a Scheduler Map to an Interface
