    Posted 29 days ago

    Hi all,

    I'm see this url   is it just need to configure at one side only?The current device in my network was MX480 and MX240. The purpose to create GRE tunnel as backup link to establish IBGP.

    Thanks and appreciate any feedback

    With CoS you need to mark on egress and process on ingress.  So if you need the queuing to occur in both directions of the flow then it would need to be setup on all devices that the flow crosses.

    Hi all,

    Just to update from JTAC regarding my issue. After junos version 18.4 the feature can see each que on GR interface already disable. So no other way we can check traffic statistic entering the que on GR interface. Hopefully if someone here from Juniper Engineering team can bring back this feature on GR interface.
