Thank you for your reply Eugene, but it's still not working for us. This is export from one of the MTs...

Router should redistribute only some 172.x.x.x and some 82.99.178.x routes but i can see eg. ranges 192.168.5.0/24 and 192.168.1.0/24 from NATed ethernet in entire network. We have this problem on all routers with 2.9.28. Some solution for this, please ??
