Abstract

The invention provides a multicasting transmission method, and relates to the field of communication. The configuration amount can be reduced, and maintaining is made to be easier. The method includes the steps that a sender PE receives an MP-BGP signaling IPv6 multicasting routing information sent by a receiver PE, the sender PE generates a multicasting forwarding table item according to the IPv6 multicasting routing information and binds the multicasting forwarding table item with an I-PMSI tunnel, and the sender PE receives the multicasting flow from a multicasting source and sends the multicasting flow to the receiver PE through the I-PMSI tunnel according to the multicasting forwarding table item.

Description

technical field [0001] The present invention relates to the communication field, in particular to a multicast transmission method, device and network system. Background technique [0002] The transition from IPv4 (Internet Protocol Version 4, Internet Protocol Version 4) network to IPv6 (Internet Protocol Version 6, Internet Protocol Version 6) network is the trend of future network development. Since the conversion from IPv4 network to IPv6 network requires a process, therefore, For a long time in the future, it is inevitable that the two networks will coexist at the same time. [0003] In the early stage of the transition from IPv4 network to IPv6 network, IPv4 network has been deployed in large quantities, while IPv6 network is only applied locally. Using 6PE (IPv6 Provider Edge, Internet Protocol version 6 operator edge router) technology, tunnels can be created on the IPv4 network, and BGP (Border Gateway Protocol, Border Gateway Protocol) can be used to exchange IPv6 ...
