DMVPN Phase 2/3 does not works with IPSec Profile
I have experienced this behaviour which without IPSec
Profile applied to the tunnel interface, DMVPN Phase 2 and 3 works where
direct spoke-to-spoke communication is possible. However, when IPSec
Profile is applied to the tunnel interface, there is no direct
spoke-to-spoke communication. It falls back to DMVPN Phase 1 behaviour
where all traffic is routed to the hub then to the destination spoke.
Anyone has experienced this as well?
I'm using v15.2(4)M5 and v15.2(4)M7 images and both gave the same behaviour.
Not sure if this behaviour is observed on the physical router as well. Appreciate if you could share some thoughts into it. Thanks.
