Layering virtual network based on tree virtual local area network (VLAN) and configuration method thereof

Abstract

The invention relates to a layering virtual network based on a tree virtual local area network (VLAN). The layering virtual network comprises a core website and an edge node, wherein the edge node is provided with a virtual switching instance which is provided with at least more than one user logic interface and at least more than one pseudowire. The invention also provides a configuration method of the layering virtual network based on the tree VLAN, comprising the following steps: (1) establishing a fully-meshed virtual special switching instance on a core node; (2) establishing a tree VLAN instance on the edge node; and (3) relating the tree VLAN instance with the core node. The invention has the beneficial effects that operation is simple and visual; the configurations can be collocated in advance in accordance with a plan; the problem that configuration parameters are input wrongly does not occur; addition/cancellation of the services is realized by only adding/cancelling a user logic port in the tree VLAN; and other related function expansion can be easily realized.

Description

technical field [0001] The invention relates to an MPLS layered virtual local area network of communication equipment and a configuration method thereof, more specifically, to a layered virtual local area network based on a tree-shaped virtual local area network and a configuration method thereof. Background technique [0002] Currently, the common configuration methods in hierarchical virtual switching instances of MPLS communication equipment are as follows: [0003] 1) Configure full-mesh virtual switching instances between core nodes; [0004] 2) On the edge node, configure the point-to-point pseudo-wire service; [0005] 3) The point-to-point pseudowire service will be added to the core node as a logical interface of the virtual switching instance. Configure the specified split horizon group number; [0006] 4) If the edge node has multiple services joining the virtual switching instance, then repeat steps 2 and 3. [0007] Existing method has following shortcoming:...

AI Technical Summary

Problems solved by technology

[0008] 1. For the pseudowires on the edge nodes, the relationship between each other cannot be reflected. These pseudowires have a common source node and destination node, and will be added to the same virtual switching instance at the core node, which may lead to differences from the original plan. inconsistent

[0009] 2. It is difficult to expand multiple services from one service to the same edge node on the network management

And these parameters: virtual switching instance number, split horizon group number, source node num
