Zusammenfassung:	A method for controlling transit of routing messages in a network comprising multiple autonomous systems (AS) is disclosed. The method includes receiving, at a first AS, a routing message of an inter-AS routing protocol and identifying that the routing message comprises transit domain control (TDC) information specifying one or more autonomous systems to which the routing message may be propagated and/or one or more autonomous systems to which the routing message may not be propagated. The method further includes propagating the routing message from the first AS to a second AS in accordance with the TDC information.
