    New issue discoverd, link-group dot1q - adding 3rd 10G port from 3rd
    linecard.<br>
    OSPF flapping, for some reasons even without BFD it doesn't work
    properly.<br>
    <br>
    Anyone using similar config ?<br>

      <div>About BFD on LAG:</div>
      <div>1) possible, but it will really use only one link by default
        with standard classic BFD (won't protect the LAG components
        individually, but only the virtual link) ; that is, one single
        standard BFD session is used.</div>
      <div>2) it can protect the LAG components by using " link-group
        multiple-session" in the bfd interface config, but it's
        proprietary to SE (not standard, not compatible with Micro BFD
        sessions of RFC 7130)</div>

      <div>In link-group dot1q mode, each vlan is configured with pvc

      <div>Technically there's one circuit inside the SE per physical
