Problems solved by technology

[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 IS-IS The mechanism to publish MAC information, which forms a large degree of code redundancy, also brings waste of 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 (EndSystem, end system) learns the MAC address of the end system, and encapsulates the MAC address in the form of TL...

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] Such as 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 ...

Abstract

The invention provides a method for learning a transparent interconnection of lots of links (RTILL) network media access control (MAC) address and a device. The method for learning the RTILL network MAC address comprises steps: a MAC address of a routing bridge learning end system is connected with an end system; the MAC address is sealed in a link-state packet, and is sent to an adjacent routing bridge; when the adjacent routing bridge receives the link-state packet, whether the MAC address in the link-state packet exists in local is judged; if not existing, the MAC address in the link-state packet is learned, a confidence value is arranged to be a confidence value of the MAC address in the link-state package; if existing, the confidence value of the MAC address is updated to be the confidence value of the MAC address in the link-state package; the confidence value of the MAC address in the link-state state adds 1, and then link-state data packages are sent to all adjacent routing bridges beside a receiving end. The method for learning the transparent interconnection of lots of links (RTILL) network media access control (MAC) address and the device do not affect original TRILL link-state databases to synchronize, do not depend on TRILL routings, are simple in implementation mode, and save 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 intermediate system (IS-IS, The design idea of ​​IntermediateSystem-to-IntermediateSystem) is introduced into the Layer 2 network, and necessary transformation is carried out, so as to organically integrate the simplicity and flexibility of the Layer 2 with the stability, scalability, and high performance of the Layer 3. [0003] A device running the TRILL protocol is called a routing bridge (RB, RBridge). At the entra...
