No, aiui, the trust model is the same. If a peer announces routes to you, all you can do is: - throw away "martians" (routes to known-reserved/bad parts of IP space) - throw away stuff you know they shouldn't be announcing (your stuff basically) other than that, I think you have to trust them when they say that they have a magic route to IP 16.0.0.1 which is shorter than any other you know about. (Since it might be true).
