Hi,
I was under the impression - If the remote end gets an error it asks the sending
device to retransmit. This retransmitted packet came from the originator not the
router. The store and forward as I understood it got a packet if all looked ok it sent
it on if not it dropped it and sent back an error message.
Does the router keep the packets once forwarded? No I don't think so.
I would need to read this again but I think it was in the
