Session timeout when suing IPsec VPN

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.

Since there has been no response to your post, it appears to be either too complex or too rare an issue for other forum members to assist you. If you don't get a suitable response to your post, you may wish to review our resources at the online Technical Assistance Center (http://www.cisco.com/tac) or speak with a TAC engineer.

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.
