I've seen this as well, including in an SDH transport, where OSPF
packets were being eaten (something Multicast-related).

That's what I was thinking at first when I read the OP's post. If the
circuit is being transported over MPLS or being fronted by an Ethernet
switch, Level(3) would have to tunnel Layer 2 protocols in order to
support your LACP frames across the pw.
