Method and device for solving oscillation problem of multi-virtual registration protocol (MVRP) loop of local area network

Abstract

The invention discloses a method for solving the oscillation problem of a multi-virtual registration protocol (MVRP) loop of a local area network. The method comprises the following step of: if any port on the MVRP loop of any example is used as a temporary example port of the example, opening a fixed mode of the example on the port when an MSTP (Multiple Spanning Tree Protocol) message with information that the port as a blocking port of the example is in a blocking state in the example is received through the port. Based on the same inventive concept, the invention also provides a device capable of avoiding the oscillation of the MVRP loop on the basis of reducing the management workload, lowering the difficulty and ensuring the flexibility of an MVRP.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and a device for solving multiple VLAN Register Protocol (MVRP) loop oscillation. Background technique [0002] As a carrier of an attribute registration protocol, Multiple Register Protocol (MRP) can be used to disseminate attribute information. The application entities following the MRP protocol are called MRP applications, and MVRP is one of the applications of MRP. MVRP is used to publish and learn virtual local area network (Virtual Local Area Network, VLAN) configuration information between devices, so that devices can automatically synchronize corresponding VLAN configurations, reducing the configuration work of network administrators. After the network topology changes, MVRP republishes and learns VLANs according to the new topology, so as to achieve real-time synchronous update with the network topology. MVRP has a feature, that is, if a port is not add...

Problems solved by technology

[0006] In order to solve the above loop flapping problem, the following two methods are adopted in the existing implementation: the first one is to create a static VLAN100 on the device 101, so that port P1 and port P2 are always in instance 1, and will not be registered due to the MVRP protocol However, although the loop can always exist and remain stable, it reduces the flexibility of MVRP and increases the workload and difficulty of the network administrator.

The second is to change the priority or path cost of the devices in the ring, so that the blocked port calculated by the spanning tree in the ring is not port P6 or port P3. When other ports are selected as blocked ports, the ring will not be affected stability, but loses the flexibility of MSTP spanning tree calculation and affects the network topology
