We are using GRE over IPSec tunnel on one of our routers. The router is polled every 5 min for its status using Cisco works 2000 server. Now, my question is if there is any way i can monitor the ipsec tunnel. Reason is because the Tu0 logical interface always remains up no matter the crypto session is down. I would like to get alerted when the crypto session goes down. Is there any way to accomplish this. Appreciate your assistance on this. Thanks!
