Problems solved by technology

[0003] In the TRILL network, tenants (English: Tenant) can be divided by virtual local area network (English: VirtualLocalAreaNetwork, referred to as VLAN), and each tenant corresponds to a VLAN. In the existing TRILL network communication method, when the routing bridge receives flooding When sending a message, according to the VLAN information contained in the flooding message, determine the multicast forwarding table corresponding to the VLAN information, and send the flooding message according to the determined multicast forwarding table, so as to ensure the flooding of each tenant. Flood packets are only limited to the VLAN to which the tenant belongs; however, according to the 802.1Q standard, the VLAN field supports a maximum of 4094 VLANs, that is to say, in a TRILL network, the maximum number of tenants supported is no more than 4094. Therefore, it cannot satisfy Practical Application Requirements for TRILL Network Development

Embodiment Construction

[0040] In order to make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be described clearly and completely in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of the embodiments of the present invention, not all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0041] The routing bridge (English: Routing Bridge, RB for short) applied in this embodiment is a switch in a multi-link transparent interconnection (English: Transparent Interconnection of Lots of Links, TRILL for short) network, which has both a layer 2 forwarding function and a layer 3 routing function.

[0042] Among them, the TRILL...

Abstract

The embodiment of the invention discloses a TRILL network communication method, device and system. The routing bridge receives the message, if it is determined that the message is a flood message, then obtain the broadcast subdomain information and the virtual local area network VLAN information of the flood message; according to the broadcast subdomain information and the VLAN information , determining a multicast forwarding table of the flooding message; copying and sending the flooding message according to the multicast forwarding table. The present invention can realize the allocation of the same access VLAN for different tenants in the TRILL network, so that the number of tenants in the TRILL network can break through the limitation of the number of VLANs and meet actual application requirements.

Description

Technical field [0001] The embodiment of the present invention relates to the field of network communication technology, and in particular to a TRILL network communication method, device, and system. Background technique [0002] Transparent Interconnection of Lots of Links (English: TransparentInterconnectionofLotsofLinks, TRILL for short) is a Layer 2 network standard recommended by the Internet Engineering Task Force (English: InternetEngineeringTaskForce, IEIF for short) to solve the spanning tree protocol in large data centers (English: DataCenter, DC for short) (English: SpanningTreeProtocol) deficiencies. [0003] In the TRILL network, tenants (English: Tenant) can be divided by virtual local area networks (English: VirtualLocalAreaNetwork, VLAN for short). Each tenant corresponds to a VLAN. In the existing TRILL network communication method, when the routing bridge receives the flooding When sending a message, according to the VLAN information contained in the flooding mes...
