OSPF, GRE Tunnel and IPSec

Does anyone have experience with configuring GRE Tunnel over IPSec with OSPF between Mikrotik and Cisco router.
Only IPSEC or GRE Tunnel between Cisco and Mikrotik routers is not a problem, but IPSEC and GRE Tunnel in combination, that’s the problem. I guess, when I solve this, OSPF will not be a problem.

Hi,
Can cisco router make multi IPSEC and to connect with a lot mikrotik branches, Can I implement this ?
I think mikrotik do not support GRE or VMVPN and I probably can not connect multi peers on cisco router.
