Hi Brian, Perhaps this was not clear from the description in section 4.1.4 of RFC, however section 5.4 brings more doubts: In figure 16, the "B"-side (the side that receives Link Status Processor Recovered message), after receiving LS PR and after sending LS Ready (stream 1) message "has completed synchronization of sequence numbers and has sent LS Ready, so it is able to resume sending data at this point with the new sequence numbers". A side (the side that recovered from PO) sends the second LS Ready (stream 1) but it seems noone does anything with that message: if the purpose of synchronization was to send the last received BSN to synchronize FSNs at remote peer, then two messages seem to be sufficient?
