Problems solved by technology

However, the change of D-VLAN will destroy the state of the neighbors, causing all neighbors to renegotiate, which will eventually lead to the recalculation of the traffic forwarding path of the entire network, and the traffic forwarding will be interrupted
Therefore, the switching of D-VLAN has a great impact on the network

Abstract

The invention discloses a method and a device for configuring a network. The method includes: determining that the first RB joins the current broadcast network; determining that the first RB does not support the D-VLAN of the current broadcast network, and determining the first VLAN jointly supported by the first RB and RBs belonging to the D-VLAN; Send alternative D-VLAN information in the D-VLAN and the first VLAN, where the alternative D-VLAN information includes the identifier of the first VLAN; determine all neighbors in the first VLAN maintained locally When the state is the report state, the switching information including the identifier of the first VLAN is sent in the D-VLAN, so that the RBs belonging to the D-VLAN switch to the first VLAN according to the switching information. The method and device of the embodiment of the present invention can avoid the impact on traffic forwarding when D-VLAN is switched, and can obtain the maximum connectivity of the network, thereby significantly improving the usability of the network.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and a device for configuring a network in the communication field. Background technique [0002] Transparent Interconnection of Lots of Links (Transparent Interconnection of Lots of Links, referred to as "TRILL") protocol introduces Intermediate System to Intermediate System (Intermediate System to Intermediate System, referred to as "ISIS") in the second layer (data link layer) of the Internet protocol stack to realize the bridge ( bridge) to the network bridge, so as to be applicable to the scenario where the virtual machine (Virtual Machine, referred to as "VM") in the data center network migrates within the network segment. [0003] Compared with the traditional Layer 2 technology, the technology based on TRILL protocol has the following advantages: both unicast and multicast support Equal Cost MultiPath (ECMP), and the bandwidth utilization rate is high; unicast tr...
