Also introduced the notion of instance (Instance) among the MSTP; With a plurality of VLAN (Virtual Local Area Network; VLAN) is mapped in the instance; Saving communication overhead and resources occupation rate, the calculating of each instance topology of MSTP is independently (the corresponding independent generation tree of each instance), thereby can on these instances, realize the load balancing of vlan data.
In order to realize load balancing, require the territory configuration information of each equipment in the Multiple Spanning Tree (MST) region necessary identical based on VLAN.The territory configuration information comprises the mapping relations (give tacit consent to whole VLAN and be mapped to instance 0) of domain name (acquiescence is the bridge MAC Address), MSTP revision level (acquiescence is 0), VLAN and instance.As shown in Figure 1, device A and equipment B in the same Multiple Spanning Tree (MST) region all have following territory configuration information:
Domain name: aaa;
MSTP revision level: 0;
The mapping relations of VLAN and instance: instance 0 has mapping relations with VLAN 3-4094, instance 1 has mapping relations, instance 2 and VLAN 2 with VLAN 1 and has mapping relations.
Can guarantee loop can not occur based on MSTP, and in order to guarantee not occur loop, can make instance 1 block at port 4 through the parameter of each instance of adjustment, instance 2 blocks at port 3, on the basis that loop do not occur, realizes the load balancing based on VLAN.
In Fig. 1, periodically carry BPDU (Bridge Protocol Data Unit, the BPDU) message of self territory configuration information between device A and the equipment B alternately; After device A received the BPDU message from equipment B, if the territory configuration information of the equipment B of wherein carrying is identical with the territory configuration information of device A, then device A knew that the BPDU message is the message from same Multiple Spanning Tree (MST) region; In like manner, equipment B can know that the BPDU message from device A is the message from same Multiple Spanning Tree (MST) region.
In the prior art, revise the territory configuration information (, perhaps increasing the mapping relations of an instance 3 and VLAN3) of device A and equipment B if desired, then need make amendment the territory configuration information of device A and equipment B as domain name is revised as bbb.
Be example earlier device A is made amendment, after the territory of device A configuration information is revised completion, will carry amended territory configuration information in the BPDU message that device A is periodically sent; After equipment B receives this BPDU message; The territory configuration information that can know device A is different with the territory configuration information of self; Can think that this BPDU message is from overseas message this moment; Device A is overseas equipment, and then the port role and the port status that cause equipment change, and causes network topology to be vibrated.After this, after the territory of equipment B configuration information revise to be accomplished, equipment B will think again that device A is the equipment territory in, so network topology can vibrate again, and finally return to the territory configuration information and revise preceding topological state.
Therefore, the method for modification of the prior art territory configuration information can cause network topology to be vibrated, and then the business that possibly cause moving interrupts, and badly influences the service quality of network.
