  • 1.  Default ethernet traffic?

    I've got a short question about traffic on an ethernet trunk link.
    On a MX204 edge router we've got multiple ENNI's with each a few hundred VLANs configured on them.
    Each VLAN represents a specific customer where we receive traffic from our ENNI carrier.
    On a few VLANs, where no customers are connected to, we still seem to send a few egress frames to our ENNI carrier.

    We wonder what this traffic could be. 
    The 'monitor traffic interface xxxxx' command does not tell us anything.
    Perhaps I'm missing basic ethernet or data link layer knowledge, but to my knowledge we should not see any frames to be received or sent at all.
