I have the follow setup:
Cisco ASR1001-x - Mikrotik RB750Gr3 IKEv2 IPSec with certificates.
During peers authentication with Cisco certificate I see "IPSec trailing data after last payload @1be" message in Mikrotik IPSec debug following "invalid reply" and "killing ikev2 SA" then.
The crypto ikev2 sa status is ready on Cisco side.
Question is: Have someone met the same error ?
