摘要： A method and apparatus for routing multicast data across multiple multicast routing domains connected by a shortest path bridging (SPB) network is presented. A Shortest Path Bridging (SPB) edge router of an SPB network connected to a PIM network is configured as a Rendez vous Point (RP). A message is received at the RP, and in response, the RP forms a first structure including multicast sender information. The RP floods the SPB network with a second message containing the first data structure, allocates an Identifier (ISID) to the multicast stream, and sends a second data structure with sender information. An edge router with multicast receive interest responds with the second data structure with multicast receive interest information. As a result, a receiver in a second network has knowledge of devices in a first network such that multicast traffic is able to be routed between different networks connected to the SPB network.

摘要翻译： 一种用于路由在由最短路径桥接连接的多个多播路由域的组播数据的方法和装置（SPB）网络被呈现。 最短路径连接到PIM网络SPB网络的桥接（SPB）边缘路由器被配置为海天盛筵点（RP）。 消息在RP被接收，并且作为响应，RP形成第一结构，包括多播发送器的信息。 该RP充斥SPB网络与第二消息包含第一数据结构，分配给标识符（ISID）多播流，并发送一个第二数据结构与发送者信息。 与多播的边缘路由器接收与多播接收感兴趣信息的第二数据结构的兴趣响应。 其结果是，在第二网络中的接收机具有的设备在第一网络搜索知识没有多播流量能够连接到SPB网络不同的网络之间路由。
