Is it possible on MT to use, for example, filters to prevent asymmetric routing? Without manual control of the cost parameter.

I've never seen that on any other architectures... but if you have designed your network with OSPF, then you will be able to prevent asymmetric routing (which by the way, in some situations works really great, as example when you want to send the upstream traffic over one link and the downstream traffic with another one.

I use ospf on dynamic links in wide area networks only to provide a loopback address for the bgp protocol. I would be pleased if there was a simple method to prevent this.

I think that I can works with a script, but it will involve some work trying to figure it out which circuit is experimenting interference.
