Title:
MULTICAST METHOD AND ROUTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/098597
Kind Code:
A1
Abstract:
Disclosed in embodiments of the present application are a multicast method and a routing device. The method comprises: when a multicast group accesses a first routing device, the first routing device allocates a multicast segment identification for the multicast group, the multicast segment identification being used for indicating that a currently borne service is a multicast service; the first routing device notifies other routing devices in a segment routing domain of a message carrying the multicast segment identification; when a second routing device creates, according to the received message, a tunnel for bearing multicast data, the first routing device receives the multicast data forwarded by means of the tunnel, wherein the second routing device is a source access node device of the multicast group. According to the embodiments of the present application, a multicast service can be flexibly borne in an SR network, and the working efficiency of the SR network is fully utilized.
