Re: Query Regarding M2PA Rfc 4165

Amit,

How can one side buffer data in LPO and RPO.  I don't think that it can.
The other side cannot send messages in this state and the near side cannot
acknowledge them in this state.

If you think this can occur, you need to detail the events leading up to
and after both LPO and RPO in your example.
