Hello:
'Path.Max.Retrans' parmeters specifies the maximum number of retransmission on a path before that path is marked down.
Section 8.3 of RFC says:
When the value of this counter ""reaches"" the protocol parameter
'Path.Max.Retrans', the endpoint should mark the corresponding
destination address as inactive if it is not so marked, and may also
optionally report to the upper layer the change of reachability of
this destination address.
This will make the Heartbeat to be re-transmitted one count less then 'Path.Max.Retrans'
This is correct in Section 8.2 which says:
When the value in the error counter ""exceeds"" the protocol parameter
'Path.Max.Retrans' of that destination address, the endpoint should
mark the destination transport address as inactive, and a
notification SHOULD be sent to the upper layer.
So Section 8.3 should be modified and a path should be marked down when error count exceeds 'Path.Max.Retrans'.
