A method and apparatus for providing multicast messages across a data communication network, the method comprising receiving a multicast message and adding to the multicast message a vector stack including at least one address of a router to which the multicast message is to be sent. The multicast message and the vector stack are then forwarded. At the first router indicated by the vector stack, the next address to which the multicast message is to be sent is read. This is repeated as necessary until the multicast message is received by the final address in the vector stack. The multicast message is then routed to the address indicated in the original multicast message.
