The SAP egress QoS policy defined forwarding class and profile reclassification rules are not applied to egress routed packets. To allow for egress reclassification, a SAP egress QoS policy ID may be optionally defined on the IP interface that is applied to routed packets that egress the SAPs on the VPLS or I-VPLS service associated with the IP interface. Both unicast directed and MAC unknown flooded traffic apply to this rule. Only the reclassification portion of the QoS policy is applied, which includes IP precedence or DSCP classification rules and any defined IP match criteria and their associated actions.
The policers and queues defined within the QoS policy applied to the IP interface are not created on the egress SAPs of the VPLS service. Instead, the QoS policy applied to the egress SAPs defines the egress policers and queues used by both routed and non-routed egress packets. The forwarding class mappings defined in the egress SAP’s QoS policy also defines which policer or queue handles each forwarding class for both routed and non-routed packets.
