<p>The present invention discloses a method and a device for converging a layer 2 multicast network, and pertains to the communication field. The method includes: if a device in a layer 2 multicast network detects that a topology of the layer 2 multicast network changes, by the device: receiving a query command sent by an upstream device, and multicasting the query command to a downstream device; generating a query response according to a layer 2 multicast forwarding table of the device, where the query response carries channel information requested by a user; receiving a query response sent by the downstream device, and storing the channel information requested by the user carried by the received query response and a forwarding port receiving the received query response into the layer 2 multicast forwarding table; and sending the generated query response and the received query response to the upstream device. The device includes: a receiving module, a first generating module, a storing module, and a sending module. With the present invention, the convergence of the layer 2 multicast network can be faster when the topology of the layer 2 multicast network changes.</p> |
