Abstract
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...
