    Is there anyway to mark outgoing PPPoE & PPP control packets using a predefined 802.1p marking in Juniper E series? I cannot see details in any of JunosE configuration guide.

     

    Any advice regarding the above will be helpful.

    Hi,

     

    afaik there is no build-in mechanism for this.

     

    A proposed workaround for this is:

     

    1. on all ingress mark all pakets with an appropiate user-packet-class (not using at least one possible user-packet-class value),

    2. on the egress: if a packet leaves the router which doesn´t have a user-packet-class as assigned by 1. it must be packet generated by the router internally, so control-traffic (PPP, PPPoE, ICMP, IGMP etc.). So set 802.1p / user-priority to the desired values.

     

    Please let me know if this works for you.

     

    Best Regards
