  • Support for BGP flowspec DSCP action (MX Series and PTX Series)—Starting in Junos OS Release 22.1R1, you can configure BGP flowspec DSCP action to use forwarding class and loss priority information to forward packets across the network. With this feature enabled, the router forwards traffic to the intended CoS queues, where CoS policies are applied to the traffic correctly. This feature also influences local forwarding behavior (for example, selection of the tunnel) based on the provisioned DSCP value.
