Dear Experts
As known in juniper routers the network control traffic by default will be queued in the default queue # 3 which by default called network-control, my questions are
How this forwarding will be forwarded to the queue without applying and classifier on the control plane or even in interface fxp1?
Another question which will depend on the answer of the first one
If we modified the queues to carry different code points as shown below, will the control traffic such as BGP messages will follow these changes or it will go to the default queue # 3 without consideration for the code-points value assigned to that queue.
The default Queues Configuration
[edit class-of-service]
forwarding-classes {
queue 0 best-effort;
queue 1 expedited-forwarding;
queue 2 assured-forwarding;
queue 3 network-control;
The Modified configuration for example
forwarding-classes {
queue 7 nc;
queue 4 af41;
queue 3 af31;
queue 2 af21;
queue 0 be;

Mohamed Edrees
