Re: [6tisch] SeqNum definition in RFC8480 (6P)

Thanks, Diego! I think, if SeqNum=0 has the special meaning, 6P would need to pass a received SeqNum to a corresponding SF... But, my understandings is that, SeqNum is maintained only by 6P and not revealed to SFs... An alternative way to tell a power-cycle event to the peer would have been

Hi Yatch, thanks for your observation. I think that the behaviour is correct as described in the text. When node B power cycles loses the last seen seqNum. Its stored value is then 0 and hence when it receives the request responds with the error and with the stored last seen seqnum (0). does it

2019-04-19 Thread Yasuyuki Tanaka
Hi, I came across a question in RFC8480 (6P), which looks like an error to me... Can anybody help? This is about the SeqNum field of the 6P header. Section 3.2.2 defines SeqNum like this: [https://tools.ietf.org/html/rfc8480#section-3.2.2] > SeqNum: The sequence number associated with the 6P
