In general, techniques are described for distributed route and packet flow evaluation within a cloud exchange fabric. In some examples, a routing engine is operative to: establish sessions between a first network and a second network to exchange message data identifying destinations in the second network; and verify routing information comprising routes from endpoints in the first network to the destinations based upon the message data, including, for each route of the routes: evaluating a source or a destination for indicia of illegitimate origination, and in response to detecting an illegitimate endpoint at the at least one of a source or a destination based upon identifying one or more of the indicia of illegitimate origination, dropping a corresponding route from the routing information.
