Static BFD session not come UP vs Huawei ME60

    Hi experts:

    Hardware: Summit X670G2-48x-4q
    ExtremeXOS version: 16.1.2.14

    I hope you can help me in this little issue, I am trying to bring up a BFD session in a p2p link from my x670 Extreme Stack with a Huawei Router ME60 in the other side, I have currently a BGP session ESTABLISHED between them, but the BFD is not coming UP.

    On both sides I'm trying to configure BFD protection to keep checked the remote loopback reached by a static route (loopbacks interfaces where the BGP session is created).

    First of all I tried to match the timers on Tx/Rx and the Multiplier 50,50 (minimum allowed on extreme side) and 3 (multiplier) with no results.

    After that we changed to 1000ms on Tx/Rx on extreme side, then to 13500ms, then changed back to 50 and changed the local Discriminator as 1 in both sides. No results.

    In the log always I'm getting the following message:

    <"Received BFD an invalid packet on VLAN XXXXXX Error:Invalid ttl value for single Hop session">

    I tried to shutdown/no shut ports , What can be the issue now???????? suggestions?????

    Here I share the output and config from both nodes:

    Please note that the Huawei router is under customer permises so I do not have the control to access this, each change I request is needed a customer intervention.

    Thanks in advance for your thougts/suggestions.
