A method includes receiving, at a first edge node, an Internet Protocol (IP) multicast address of a first silent host node. The method further includes receiving, at a second edge node, an IP multicast address of a second silent host node. The IP multicast address of the first silent host node is equal to the IP multicast address of the second silent host node. The method further includes storing the IP multicast address of the first and second silent host node in a shared entry of a routing table. The method further includes receiving, at a third edge node, a packet from a third host node and determining that a destination address of the packet corresponds to the IP multicast address stored in the shared entry of the routing table. The method further includes sending the packet to both the first host node and the second host node.

Systems and methods for preventing solicited-node multicast address collisions

A method includes receiving, at a home controller of a home domain and from a first device in the home domain, a first message concerning a user device that is anchored to the home domain and that has roamed from the home domain to a visitor domain. The method also includes, in response to determining that the first device is a router, opening a tunnel between the home controller and a visitor controller of the visitor domain and communicating the first message to the user device through the tunnel. The method further includes receiving, at the home controller and from a second device in the home domain, a second message concerning the user device and in response to determining that the second device is not a router, communicating, to the second device, a proxy response to the second message.
