Not sure what you mean by single connection. If you mean an application connection, e.g. a file transfer, then yes, it will always remain on the same link. With FEC, the physical link used is determined by srcip XOR dstip or srcmac XOR dstmac Since these do not change during a session, the session will always go over one link. > My questions are: > > 1) Is is even possible to successfully "attach" vlan devices to netgraph > nodes, specifically the ng_fec node (I can't decipher enough of netgraph to > begin with to make a guess, just a copy monkey here...), i.e. have interface > fec the parent device?
