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.

I thought that early allocations were supposed to go into the document so
they don't get assigned twice by mistake.

Thank you.

Is there any reason why the source port (for DULL, and normal) can't be port 
7017 as well?
It clearly could be any port...
