Dear Haroon, IPsec works fine with IP cef and i havent observed any issues regarding it ever !!. However site to site vpn ( and others also) rely heavily on your underlying routing. So maybe if you are using cef router may be using some other path then what you expected and this might cause vpn to terminate. Check out your routing and let us know how your vpn endpoints are connected to each other.

Hi Experts,
Does IP CEF need to be enabled on both ends of a site to site IPSEC vpn for
it to work?
I am running into issues where if I enable ip cef on the main router, the
connections to other sites drops and comes back up immediately if disabled.
Is this a bug or am I missing something?
Thanks,
Haroon
