You could also hear the more specifics from another peer that is one of their transit providers or you could hear them via one of your transit providers. > I can think of a couple ways to prevent hearing these, but thought I > should ask for suggestions first. You can do all kinds of things to other network's routes especially when those routes aren't from your customers and what you are doing doesn't break connectivity (or solves a capacity problem and improves connectivity). However, if you tweak routes of a paying customer then you will need to consider what your answer to your customer will be for overriding their traffic engineering.
