Hello,
Here are my thoughts on your questions:
ECMP/weights = Correct ECMP should not be used if using weights to prefer one route/path over another.
Better to use PBF? = if preferring a route, yes you can.
The other device = Correct, the other device would need to be also setup to use PBF or something similar to ensure traffic goes back down the correct path. I prefer OSPF in this case and use route weights here. That way the other device will learn the routes and weights, etc.
Asymmetric traffic = I would make sure you dont have this scenario as it will not work. Best to go with weighted routes, etc.
Check out my reply to this post and see if it makes a bit more sense.
Hope this makes sense.
