I suspect that for most GRASP purposes, even if there is a layer 2 
network between the parties,  we are not much worried about how LAG 
handles GRASP packets?   If we care about that, then the source port 
should be randomized between flows, and stable for sequences of related 
messages.

Yours,
Joel
