NETWORK DEVICE WITH SERVICE AND CLIENT ROUTING ELEMENTS CONFIGURED TO SUPPORT ANY-SOURCE MULTICAST EXTRANETS
First Claim
1. An apparatus comprising:
- a first network device adapted for communication with a plurality of other network devices;
the first network device comprising;
a service routing element configured with a first anycast rendezvous point address so as be an anycast rendezvous point peer with at least a second network device in a service routing domain; and
a client routing element configured with a second anycast rendezvous point address so as to be an anycast rendezvous point peer with at least a third network device in a client routing domain;
wherein the first network device is configured to receive in its service routing element from a service routing element of the second network device a register message identifying a multicast source, and to provide at least a portion of the register message from its service routing element to its client routing element in a manner that allows the third network device to learn the identity of the multicast source from the client routing element.

Abstract
A first network device comprises a service routing element and a client routing element. The service routing element is configured with a first anycast rendezvous point address so as be an anycast rendezvous point peer with at least a second network device in a service routing domain. The client routing element is configured with a second anycast rendezvous point address so as to be an anycast rendezvous point peer with at least a third network device in a client routing domain. The first network device receives in its service routing element from a service routing element of the second network device a register message identifying a multicast source, and provides at least a portion of the register message from its service routing element to its client routing element in a manner that allows the third network device to learn the identity of the multicast source from the client routing element.

14. A method comprising:
-
configuring a service routing element of a first network device with a first anycast rendezvous point address such that the service routing element of the first network device is an anycast rendezvous point peer with at least a second network device in a service routing domain; configuring a client routing element of the first network device with a second anycast rendezvous point address such that the client routing element of the first network device is an anycast rendezvous point peer with at least a third network device in a client routing domain; receiving in the service routing element of the first network device from a service routing element of the second network device a register message identifying a multicast source; and providing at least a portion of the register message from the service routing element of the first network device to the client routing element of the first network device in a manner that allows the third network device to learn the identity of the multicast source from the client routing element. - View Dependent Claims (15, 16, 17, 18, 19)

20. An article of manufacture comprising a processor-readable storage medium having embodied therein executable program code that when executed by a processor of the first network device causes the first network device:
-
to configure a service routing element of the first network device with a first anycast rendezvous point address such that the service routing element of the first network device is an anycast rendezvous point peer with at least a second network device in a service routing domain; to configure a client routing element of the first network device with a second anycast rendezvous point address such that the client routing element of the first network device is an anycast rendezvous point peer with at least a third network device in a client routing domain; to receive in the service routing element of the first network device from a service routing element of the second network device a register message identifying a multicast source; and to provide at least a portion of the register message from the service routing element of the first network device to the client routing element of the first network device in a manner that allows the third network device to learn the identity of the multicast source from the client routing element.
