MPLS-1.2: MPLS Traffic Class Marking

Summary

Verify MPLS Traffic Class Marking configuration.

Testbed type

Topology:

graph LR;
A[DUT] <-- Port1/2(IPv4/6) --> B[DUT];
Loading

Procedure

Initial setup

  • Connect DUT-A port-1 to DUT-B port-2

  • Configure IPv4 addresses on DUT ports

    • DUT-A port-1 IPv4 address dpa1-v4 = 192.168.1.1/30
    • DUT-B port-2 IPv4 address dpb2-v4 = 192.168.1.2/30

  • Configure a loopback interface on both the DUT's and assign IPv4 addresses

    • DUT-A Loopback50 dpalo-v4 = 100.100.100.1/32
    • DUT-B Loopback50 dpblo-v4 = 200.200.200.2/32

  • Configure ISIS between the DUTs and advertise Loopback50

  • Enable MPLS and LDP on both the DUTs port-1 and port-2

    • /network-instances/network-instance/mpls/global/interface-attributes/interface/config/mpls-enabled
    • /network-instances/network-instance/mpls/signaling-protocols/ldp/global/config/lsr-id [DUT-A and B Loopkack50]

MPLS-1.2.1 - Configure and verify classifier to match MPLS packets and mark Traffic Class

  • Configure a classifier to match MPLS packets

    • /qos/classifiers/classifier/config/name = 'mpls-class'
    • /qos/classifiers/classifier=[mpls-class]/config/type = 'MPLS'
    • /qos/classifiers/classifier=[mpls-class]/terms/term/config/id = 'mpls-class-term'
    • /qos/classifiers/classifier=[mpls-class]/terms/term=[mpls-class-term]/conditions/mpls/config/start-label-value = 16
    • /qos/classifiers/classifier=[mpls-class]/terms/term=[mpls-class-term]/conditions/mpls/config/end-label-value = 1048575

  • Configure classifier to mark MPLS TC

    • /qos/classifiers/classifier=[mpls-class]/terms/term=[mpls-class-term]/actions/remark/config/set-mpls-tc = 5

  • Apply the classifier on DUT-A port-1

    • /qos/interfaces/interface/input/classifiers[mpls-class]/classifier/config/name

  • Validate the configuration is applied and values are reported correctly

    • /network-instances/network-instance/mpls/global/interface-attributes/interface/state/mpls-enabled
    • /qos/classifiers/classifier/state/name = 'mpls-class'
    • /qos/classifiers/classifier=[mpls-class]/state/type = 'MPLS'
    • /qos/classifiers/classifier=[mpls-class]/terms/term/state/id = 'mpls-class-term'
    • /qos/classifiers/classifier=[mpls-class]/terms/term=[mpls-class-term]/conditions/mpls/state/start-label-value = 16
    • /qos/classifiers/classifier=[mpls-class]/terms/term=[mpls-class-term]/conditions/mpls/state/end-label-value = 1048575
    • /qos/classifiers/classifier=[mpls-class]/terms/term=[mpls-class-term]/actions/remark/state/set-mpls-tc = 5
