Just wonder if anyone have any experience configuring ism-vpn-39 with gre over ipsec using HSRP virtual IP as the tunnel source and destination endpoints? My configuration is working perfectly fine if I disable ism-vpn-39 with "no crypto engine slot 0". But as soon as I re-enable this accelerator, all the tunnels drop. I'm using the latest IOS 15.3-2T.
I see why my tunnels are dropped because I couldn't ping the peer's virtual HSRP IP whenever this accelerator is activated.
I've also been having headache with this module with older IOS versions, it either crashes the router or strangely breaks the traffic between the router and the installed switch service module (SM-ES3G-24-P) after about 3 hours of operation. The fix was to upgrade to the latest IOS but then it causes the probem above. Thanks for insight.
