Router monitoring of an L2TPv2 tunnel when it goes from "est" to "nosess"?

Hi,

     I have been looking around to find some debug/syslog data to create an EEM script to monitor when an L2TPv2 goes from "est" to "nosess".  I have posted a question on the EEM script forum for some input on the script.  However, I am curious if anyone has looked or found a way to monitor the "state" of an L2TPv2 tunnel.  That way, I can possibly add it to my EEM script to re-establish the tunnel when it goes down.  For example, here is a sample of a "debug l2tp all" when the tunnel is up:

 

*Nov  3 21:25:36.064: L2TP tnl   01005:000005F0: I HELLO, flg TLS, ver 2, len 20
*Nov  3 21:25:36.064: L2TP tnl   01005:000005F0:
*Nov  3 21:25:36.064: L2TP tnl   01005:000005F0: O ZLB ACK to vpn-si1.reliablehosting.com tnl 1829
*Nov  3 21:25:36.064: L2TP tnl   01005:000005F0:

 

Thanks.

 

Jason
