Embodiment Construction

[0037] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0038] In the embodiment of the present invention, according to the instance identifier, the instance identifier in the same Trill network is globally unique, and different CE-VLANs under different RBs are added to the same instance, and the multicast forwarding table is generated through the instance in the TRILL network, and MAC learning is performed based on the instance to achieve the same Different CE-VLANs under the instance communicate with each other.

[0039] An embodiment of the present invention provides a communication method, such as figure 1 As shown, the method may include:

[0040] 110. After receiving the first packet including data information sent by the first user-side virtual network CE-VLAN, the first routing bri...

Abstract

An embodiment of the present invention provides a communication method, a routing bridge, and a network system. The communication method includes: after the first routing bridge RB receives the first message containing data information sent by the first user-side virtual network CE-VLAN, determine An instance identifier of the first CE-VLAN; the first RB sends a message containing the data information to at least one CE-VLAN identical to the instance identifier of the first CE-VLAN. In the embodiment of the present invention, after the RB receives the message containing the data information sent by the CE-VLAN, it determines the instance identifier of the CE-VLAN, and the RB sends a message containing the data information to at least one CE-VLAN that is the same as the instance identifier of the CE-VLAN. . In this way, the application instance identification realizes the communication between different CE-VLANs, and there is no need to apply public VLANs for conversion, thereby avoiding the problem of VLAN conflicts and ensuring the normal communication between CE-VLANs in the TRILL network.

Description

technical field [0001] The invention relates to the communication field, in particular to a communication method, a routing bridge and a network system. Background technique [0002] With the development of communication technology, the TRanparent Interconnection of Lots of Links (TRILL for short) network that can improve bandwidth utilization is gradually replacing the traditional Spanning Tree Protocol (Spanning Tree Protocol, STP for short) network. [0003] Different routing bridges (RBs for short) in a TRILL network have different divisions of VLAN resources, which often leads to communication barriers between CE-VLANs under different RBs. In order to solve this communication obstacle, when communicating between CE-VLANs under two RBs, select a VLAN that is not duplicated with other virtual local area networks (Virtual Local Area Networks, referred to as VLANs) in the TRILL network as the VLAN of the two RBs. The public VLAN connects two RBs to implement communication ...
