[0004] However, in the prior art, the TRILL protocol itself uses the IS-IS (Intermediate System-to-Intermediate System) mechanism to publish information, and ESADI, as a subsidiary protocol of the TRILL protocol, also borrows the IS-IS -IS mechanism to publish MAC information, which forms a large degree of code redundancy and wastes system resources

Embodiment 1
[0041] In the TRILL network, when the routing bridge learns the MAC address and floods it to the neighbor routing bridge, the routing bridge connected to the end system learns the MAC address of the end system, and then the routing bridge sends the MAC address to the receiving end except the receiving end. Neighbor routing bridges send link state packets carrying MAC addresses. To put it simply, the routing bridge learns the MAC address of the end system, encapsulates the learned MAC address in a special link state packet, and floods it to the neighboring routing bridge. The neighbor routing bridge receives the link state packet, performs some checks and proceeds to flood the neighbor.
[0042] Specifically, as figure 1 Shown, a kind of method for TRILL network MAC address learning, comprises steps:
[0043] The RB (RBridge, routing bridge) connected to the ES (End System, end system) learns the MAC address of the end system, and encapsulates the MAC address in the form of T...
Embodiment 2
[0061] Based on the method for learning a TRILL network MAC address proposed in the foregoing embodiments, this embodiment proposes a device for learning a TRILL network MAC address.
[0062] like image 3 As shown, a device for learning a TRILL network MAC address includes:
[0063] The learning encapsulation module is used to learn the MAC address of the end system and encapsulate the MAC address of the end system in the link state packet;
[0064] A judging module, connected to the learning encapsulation module, for judging whether the MAC address in the link state packet exists locally;
[0065] The first setting module is connected with the judgment module, and is used to set the local confidence value as the confidence value of the MAC address in the link state packet;
[0066] The second setting module is connected to the judging module, and is used to update the confidence value of the local MAC address to the confidence value of the MAC address in the link state pac...

Abstract
The present invention provides a method and device for learning the MAC address of a TRILL network. The method includes the steps of: learning the MAC address of the end system by a routing bridge connected to the end system; Send; when the neighbor routing bridge receives the link state packet, it judges whether the MAC address in the link state packet exists locally; if not, it learns the MAC address in the link state packet, and sets the local confidence value as link The confidence value of the MAC address in the state packet; if exist, update the confidence value of the local MAC address to the confidence value of the MAC address in the link state packet; increase the confidence value of the MAC address in the link state packet by 1, and then Send link-state packets to all neighbor routing bridges except the receiving end. The invention does not affect the synchronization of the original TRILL link state database, does not depend on TRILL routing, has a simple implementation mode, and saves system resources.
Description
technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for learning a TRILL network MAC address. Background technique [0002] In order to solve the problems of bandwidth waste and slow convergence of the spanning tree protocol, the Internet Engineering Task Force (IETF, Internet Engineering Task Force) formulated the Transparent Interconnection of Lots of Links (TRILL, TRanparent Interconnection of Lots of Links) protocol to transfer the three-layer routing technology intermediate system to the The design idea of the intermediate system (IS-IS, Intermediate System-to-Intermediate System) is introduced into the two-layer network, and necessary transformation is carried out, so as to combine the simplicity and flexibility of the second layer with the stability, scalability and High performance organically integrated. [0003] A device running the TRILL protocol is called a routing bridge (RB, RBridge). A...
