ethernet OAM/CFM frames in EVPN domain

    Hi all,

     

    Let me know if you have any test result/opinion about the following.

    CE---|  EVPN Domain(MPLS/MPLS-PBB/VXLAN either will do) |---CE

    |<---------------------------etherne CFM/OAM------------------------------>|

    I think as VPLS can transport ether CFM/OAM frames, EVPN also can do the same.

    http://www.juniper.net/documentation/en_US/junos/topics/example/layer-2-802-1ag-ethernet-oam-cfm-example-over-vpls-mx-solutions.html

     

     If you have any test result or opinion about this one please reply 🙂

     

    Regards,

    Hadi

    I've not used EVPN as yet, but I can confirm that with VPLS and l2circuits you can setup CFM tests from devices on either side of the circuit and run a complete test on the set.

     

    You do need to be sure that the maintenance domain settings used by the test set do not overlap any CFM that is configured on the devices as part of the service testing.  If they do match the packets can be caught by the service configuration instead of passing through to the test set.

    Hi Hadi.

     

    CE to CE:

     

    EOAM packets are transit packets to EVPN-MPLS, then they are treated as regular data packets and forwarded for CE to CE OAM.

     

    If you would like to run CFM session between PEs of EVPN-MPLS not supported yet. you may need to wait for upcoming release.

     

     

    Topology and results below:

     

     

    CE---|                        EVPN Domain(MPLS/)                            |---CE

    |<---------------------------etherne CFM/OAM------------------------------>|

     

    Configuration and results for CFM between CE to CE via EVPN

    Hi vvadivel,

     

    Thank you for your reply and checking the behavior in Junos device.

    Also thank you for your comment on PE-PE CFM session.

     

    Regards,

    Hadi.
