Use two classifiers, exp and inet-precedence.

class-of-service {
    classifiers {
       exp For_MPLS_traffic{
            forwarding-class expedited-forwarding {
                loss-priority high code-points [ 000 001 010 011 100 101 110
111 ];

class-of-service {
    classifiers {
        inet-precedence For-internet-traffic {
            forwarding-class best-effort {
                loss-priority low code-points [ 000 001 010 011 100 101 110
111 ];

Apply this to units on interfaces. And do not forget to configure schedulers
for this interface and divide bandwidth accordingly.

Best regards,
Bostjan Fele

Subject: [j-nsp] mpls traffic priority when P router

Hello Everybody.

I have the following setup

     Cisco    Juniper    Cisco
     7200      M5         7200

Here M5 is P and connecton between P and PE2 is limited. I have normal
traffic and mpls traffic. I need to give priority to mpls traffic
leaving the router and leave the rest as is.

The mpls is configured with ldp on the cisco side

mpls label protocol ldp
mpls ldp logging neighbor-changes
no mpls traffic-eng auto-bw timers frequency 0
tag-switching tdp router-id Loopback0 force

Problem is i dont seem to be able to classify the traffic with the filter.
I matched the ips for the l2transport route on the ciscos
 mpls l2transport route x.x.x.x 200
but the counter does not seem to count. So i'm not matching traffic. I also
don't have options to match mpls as a protocol.

The following direction is needed PE1  via ge unit , PE2 via atm unit.

Sheduler and Scheduler maps for the forwaring-class that need to set
priority are already set.
Thanks for your time.

Cyberly yours,
