Session timeout when suing IPsec VPN

[jimmy.joseph]

Hi,

Is SA life time same as Key life time?? Is there any default value for this??when a key/SA expires and new SA becomes live ..does it affect the data traffic..does packets gets dropped at the timeof change over?? or does the TCP sessions breaks??

IF my TCP sesion is idle at the time of key renewal ..does the session break?? Suppose the SA lifetime is 1 hrs..and my TCP session is idle for 1 hrs or more does it breaks the connection ??

Thanks and Regards,

jimmy.

I believe the default lifetimes for SAs are 10000 for time and 3600 for data,SA rekeys should not effect traffic at all, the session should stay alive.
