Embodiment Construction

[0039] The present invention adopts VRRP protocol to realize multicast service. The implementation method is:

[0040] Configure one or more VRRP groups;

[0041] Bind any multicast group to any VRRP group;

[0042] The routers in the VRRP group send the multicast data packets and multicast protocol packets of the bound multicast group to the multicast receiving device according to the specified VRRP state, and the routers in the non-specified VRRP state do not send the bound multicast packets. Protocol packets and data packets of a defined multicast group. In general, the specified VRRP state is the working state.

[0043] The method of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0044] Such as image 3 As shown in , it is a schematic diagram of binding a multicast group to a VRRP group. Such as image 3As shown, assuming that there are M routers in the current network, you can configure the M routers to belo...

Abstract

A method for realizing multicast service includes configuring one or multiple VRRP group, binding any one of multicast group with any one of VRRP group, sending received multicast data message and multicast protocol message generated by itself to multicast receiving device by router in VRRP group according to assigned VRRP state.

Description

technical field [0001] The invention relates to the communication field, in particular to a multicast service realization method. Background technique [0002] Usually, a host in a network sets a default route (the next hop is 10.100.10.1), so that the message sent by the host whose destination address is not in the network segment will be sent to the router (Router) through the default route, thereby realizing communication between the host and the external network. The schematic diagram of its LAN networking scheme is as follows: figure 1 shown. When a router fails, all hosts in this network segment that use this router as the next hop of the default route will cut off communication with the outside world. [0003] Virtual Router Redundancy Protocol (VRRP) is a fault-tolerant protocol. VRRP is proposed to solve the above problems, and it is designed for a local area network (such as Ethernet) with multicast or broadcast capabilities. VRRP organizes a group of routers ...
