We have a site-to-site VPN running over IPSec.
We are experiencing an intermittent problem, where connection between the two sites are lost, although the VPN channel stays / shows up. It shows "SA Established"
The one site is using a microwave link, and it seems that it happens everytime the microwave link goes down for a couple of seconds.
After the break in communication, the channel is only fully restored once one of the two routers are soft rebooted.
1. Is there way to tell one of the routers to drop / re-establish the channel if the communication between the two sites goes down?
2. Is the packets between the two routers perhaps going out of sync, and this causing the break in communication? Although the channel stays up?
