Re: Heartbeats Straw Poll
Thats a good idea, but from an implementation point of view, I am not
sure if I like the idea of maintaining a timestamp for every packet (SA
Used) through a tunnel.
I guess the problem I want to address with the heartbeats is dead-peer
detection, and as a result do action foo. INITIAL-CONTACT does help in
SADB sync'ing but is not authenticated and there is no assured delivery.
I think that Scotts point of auditing is a good side-effect of dead-peer
detection, and could also be tied to accounting, but I agree this is
outside the scope of the problem.
