Hi Paresh,

But router A will notice that the ack is for a different instance and will re-transmit the LSA.  My question is - why would router A consider it to be an ack for a different instance ?  Is the implication here that router B would set the Age in the LSAck to be MaxAge and not the Age that was present in the received LSA ?

Yes - note that the example is prefaced with "At the very worst".
