IPSEC VPN problem

Rupesh Kashyap · ‎12-30-2008

Hi,

I have created GRE Tunnel on the serial interface. Many times, it is showing IPSEC encryption problem (twice in 24 hrs). Due to this, my link flappes on intermittent basis. Please help.

Hi, It is ok & we are facing this problem 1 or 2 times a day. Rest whole day, there is not problem. How can I solve this problem as we do not want 1-2 flapping as it reestablish BGP session.
