Ramzi,
If a PATH mesg is lost while
being transmitted to the destination, it will again be transmitted to
the node at which the lost occurred after the REFRESH time period.
In all the nodes upstream to it, the PSBs have been formed and they
maintain a REFRESH timer state.
Now until these upstream nodes receive any PATH TEAR
message, their PSBs will not be deleted.
Thus when their REFRESH timer expires, they will trigger the
generation of PATH REFRESH mesgs, which would appear as a NEW PATH mesg
for that downstream node for which the PATH mesg was lost since it had
no prior PSB maintained for it.
regards,
Shilpa

what happens when a PATH message is lost while being transmitted to the destination.
a new PATH is resent? A failure is reported and that's all? is there any timer used to notice the lost message? is it the same refresh timer?
Could some please, give some clarification?
Thanks in advance
Ramzi
