Problems solved by technology

When a device in the SPB network determines that the configuration of the MSTP area changes, the recalculated primary MCID and secondary MCID will change, causing the neighbor relationship to be interrupted, and SPBM traffic will not be forwarded

Embodiment Construction

[0020] The present invention provides an efficient and feasible solution to deal with the remaining technical problems in the standard, such as figure 1 As shown, the present invention provides a method for maintaining neighbors, which specifically includes the following steps:

[0021] Step 101, acquire the primary multiple spanning tree configuration identifier MCID and secondary MCID of the SPBM neighbors.

[0022] Step 102, storing the same MCID among the primary MCID and secondary MCID of the local device and the primary MCID and secondary MCID of the SPBM neighbor as a standard MCID.

[0023] Step 103: Calculate the current primary MCID and current secondary MCID of the local device according to the information of the changed non-SPBM instance in the MSTP area.

[0024] Step 104, determine the change of the current primary MCID of the local device, set the current secondary MCID of the local device according to the standard MCID, and maintain the neighbor relationship w...

Abstract

The invention discloses a method and device for maintaining neighbor relationship, wherein the method includes: obtaining the primary multiple spanning tree configuration identifier MCID and secondary MCID of the SPBM neighbor; combining the primary MCID and secondary MCID of the local device with the primary MCID and The same MCID in the secondary MCID is stored as a standard MCID; calculate the current primary MCID and current secondary MCID of the local device according to the information of the non-SPBM instance in the MSTP area of ​​the change; determine the current primary MCID change of the local device, Set the current secondary MCID of the local device according to the standard MCID, maintain the neighbor relationship with the SPBM neighbor, and keep the normal forwarding of SPBM traffic.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for maintaining neighbors. Background technique [0002] SPB (Shortest Path Bridging, shortest path bridge) protocol is one of the Ethernet standards defined by IEEE802.1aq. It is a further extension of STP (Spanning Tree Protocol, Spanning Tree Protocol) technology, aiming to build a large flat non-blocking layer 2 network . The SPB protocol introduces the design idea of ​​the three-layer routing technology IS-IS (Intermediate System-to-Intermediate System, intermediate system to intermediate system) into the two-layer network, avoiding the slow convergence speed and partial link utilization efficiency caused by the use of STP low deficiency. [0003] 802.1aq defines two SPB modes: VLAN mode (SPBV, Shortest Path Bridging Vlan, shortest path bridge Vlan) and Mac-in-Mac mode (SPBM, Shortest Path Bridging MAC, shortest path bridge MAC), where the protoc...
