Roadmap for Configuring CoS with IPv6 DiffServ
To configure class of service (CoS) over IPv6, you must:
- Configure a multifield (MF) classifier for IPv6 to detect
packets of interest to CoS and assign the packet to the proper forwarding
class independently of Differentiated Services Code Point (DSCP).
See Configuring a Firewall Filter for an MF Classifier on Customer Interfaces.
Next, apply the MF classifier to the appropriate interface. See Applying the Firewall Filter to Customer Interfaces.
- Assign the forwarding classes established by the MF classifier to output queues. See Assigning Forwarding Classes to Output Queues.
- Configure rewrite rules to replace DSCPs on packets received
from the customer with the values expected by other routers. See Configuring Rewrite Rules.
Next, apply the rewrite rules to the appropriate interface. See Applying Rewrite Rules to an Interface.
- Configure behavior aggregate (BA) classifiers for IPv6
on network interfaces because the DSCPs have been explicitly rewritten
on the edge routers. See Configuring BA Classifiers.
Next, apply the BA classifier to the appropriate interface. See Applying a BA Classifier to an Interface.
- Configure random early discard (RED) drop profiles to determine the probability of DiffServ assured forwarding packets being discarded under congested conditions. See Configuring RED Drop Profiles.
- Configure schedulers to assign resources, priorities, and drop profiles to output queues. See Configuring a Scheduler.
- Configure a scheduler map to assign a forwarding class
to a scheduler. See Configuring Scheduler Maps.
Next, apply the scheduler map to the appropriate interface. See Applying a Scheduler Map to an Interface.
