To all,

Has anyone successfully tunneled L2 PDU's (STP, CDP, LLDP) over a L2TPv3 pseudowire tunnel, i.e. should I be able to see CDP neighbors across the tunnel? For some reason if I encapsulated dot1q on a router sub-interface and try and pass traffic across the trunk the downstream switch port will go into err-disable.
