Problems solved by technology

[0008] To sum up, in the current RRPP network structure, the refresh method of MAC entries and ARP / ND entries is: refresh by sending flush-FDB packets, which requires all devices in the RRPP network to be able to identify flush-FDB packets, otherwise, MAC entries and ARP / ND entries cannot be refreshed immediately after topology changes, thus limiting the networking application of RRPP devices and other manufacturers' devices
[0009] In the current Smart Link networking structure, the refresh method of MAC entries and ARP / ND entries is: refresh by sending flush packets. This method requires all devices in the Smart Link networking to be able to identify flush packets, otherwise , MAC entries and ARP / ND entries cannot be refreshed immediately after topology changes, thus limiting the networking application of Smart link devices and other manufacturers' devices

Embodiment Construction

[0035] The present invention provides a management method for forwarding table items, aiming at network devices that do not support specified topology protocols (such as RRPP protocol or Smart Link protocol) in the prior art, and cannot timely delete forwarding table items (such as MAC table items and ARP / ND table entry), by using MVRP packets (in practical applications, it can also be MSTP topology change packets, and MVRP packets will be used as an example to explain later), notify network devices that do not support the specified topology protocol to delete forwarding entries in time .

[0036] MVRP is the application of MRP (Multiple Register Protocol) on VLAN attributes. It is used to publish and learn VLAN configuration information between devices, so that devices can automatically synchronize VLAN configuration information and reduce the configuration work of network administrators; After a change occurs, MVRP republishes and learns VLAN configuration information accord...

Abstract

The invention discloses a management method and equipment for a forwarded table entry. The method comprises the following steps: control equipment finds that a network topology is changed; and the control equipment sends a multiple VLAN (Virtual Local Area Network) registration protocol (MVRP) message to network equipment which does not support an appointed topology protocol to indicate the network equipment which does not support the appointed topology protocol to clear a self forwarded table entry. In the method, the network equipment which does not support the appointed topology protocol can delete the forwarded table entry in time in the scene of the appointed topology protocol, and the traffic flow in the network is restored in time.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a management method and equipment for forwarding entries. Background technique [0002] Currently in the networking structure of RRPP (Rapid Ring Protection Protocol, fast ring protection protocol), including: (1) RRPP domain, with the same domain ID (identification) and control VLAN (Virtual Local Area Network, virtual local area network), And the interconnected devices form an RRPP domain, and an RRPP domain includes elements such as RRPP main ring, sub-ring, control VLAN, main node, transit node, main port and secondary port, public port and edge port. (2) RRPP ring, a ring-connected Ethernet network topology is called an RRPP ring, and the RRPP ring is divided into a main ring and a sub-ring. (3) Control VLAN and data VLAN, the control VLAN is used to transmit RRPP protocol messages, and the data VLAN is used to transmit data messages. (4) Nodes. Each device on the R...
