DSVPN + IPSec at one end only

Hi,

I have many spokes-hub IPSec+DSVPN network. I have noticed that if a simple misconfiguration happens resulting that at one end (router) there is no ipsec profile command on the tunnel interface (regaldless if I refer to spoke-hub or spoke-spoke connection) there is still possible to comunicate. There are just no IPSec SAs obviously, but NHRP delivers with routes and traffic flows so connectivity is a fact.

My question is : Is there a way to ensure that if there is no ipsec profile command at the tunnel int of one end and there is ipsec profile at the other end's tunnel (of the hub for example or the other spoke)  the latter will somehow block the unencrypted traffic totaly ?

I tried ipsec decrypt check, but it seems to be a command for other scenarios.

It's a bit of an issue in terms of security and i failed in figuring out the solution so far.

Any advice welcome :)

Or maiby its a soft bug or something
