401, when receiving the registration revocation message, according to the GMAC address in the registration revocation message from transmit the GMAC address and the corresponding relation of interface identifier in deletion receive the interface identifier of the interface of registration revocation message.
When switch receives the registration revocation message, switch receives the interface identifier of registration revocation message according to deletion in the corresponding relation of this GMAC address and the interface identifier from transmit of the GMAC address in the registration revocation message, to realize the switch registration revocation.Need to prove that when carrying out registration revocation, when corresponding interface identifier has only one in transmitting as if the GMAC address in the registration revocation message, switch will be deleted this GMAC address and corresponding interface sign from transmit.
Need to prove that the registration revocation message can be generated and sent by the switch that obtains the registration revocation order, in embodiments of the present invention, the registration revocation order is sent by network management device, is perhaps disposed on switch by administrative staff.Comprise the corresponding relation between MAC Address, GMAC address and the interface identifier of two layers of control protocol that need un-register in the registration revocation order.After switch obtains the registration revocation order, according to the MAC Address that disposes on the interface identifier corresponding interface in the order of registration revocation order deletion registration revocation and the corresponding relation of GMAC address, and, delete in the interface identifier with the GMAC address correspondence of this registration revocation order from transmit of the interface identifier in the registration revocation order according to GMAC address and the interface identifier in the registration revocation order.Be specially: when corresponding interface identifier has only one in is transmitting the GMAC address in the registration revocation order, this GMAC address of deletion and corresponding interface identifier thereof from transmit.And for example, when the interface identifier of correspondence is more than one in is transmitting the GMAC address in the registration revocation order, interface identifier from transmit in the order of deletion registration revocation is not deleted other corresponding with the GMAC address of registration revocation order in transmitting interface identifier.
When switch is deleted the GMAC address in the registration revocation order and the corresponding relation between the interface identifier according to the registration revocation order from transmit after, when transmitting the GMAC address that does not have in the registration revocation order.Perhaps when in the corresponding relation of this GMAC address from transmit and interface identifier with corresponding interface identifier deletion after, in transmitting this GMAC address only corresponding during an interface identifier, when the number of the interface identifier of this GMAC address correspondence is no more than 1 in promptly transmitting, switch generates according to the registration revocation order and carries the registration revocation message of GMAC address, sends the registration revocation message that generates to the network side interface.Optionally, in the corresponding relation of this GMAC address from transmit and interface identifier with after the corresponding interface identifier deletion, in transmitting this GMAC address only corresponding during an interface identifier, the registration revocation message that also can be only sends to the corresponding interface of the interface identifier of this GMAC address correspondence.
When 402, the religion order of corresponding interface identifier is no more than 1 in is transmitting the GMAC address in the registration revocation message, transmit the registration revocation message.
Switch according to the registration revocation message to transmit delete after, if transmit the GMAC address that does not comprise in the registration revocation message or transmit in this GMAC address only corresponding during an interface identifier, switch is transmitted the registration revocation message that receives to the network side interface.Optionally, in transmitting this GMAC address only corresponding during an interface identifier, also can be only transmit the registration revocation message that receives to the corresponding interface of the interface identifier of this GMAC address correspondence.
In embodiments of the present invention, switch is carried out the operation of registration revocation, make carrier network can effectively control the transparent transmission of two layers of control protocol message by utilizing registration revocation order or registration revocation message.
Technical scheme for a better understanding of the present invention, the method of carrying out message process registration and registration revocation on a plurality of switches will be introduced, see also the user network shown in Figure 1 and the system diagram of carrier network, will need transparent transmission STP agreement with switch A and switch b in application examples of the present invention is that example is introduced technical scheme of the present invention.
1) when needing transparent transmission STP agreement between switch A and the switch b, switch 1 obtains the two-layer protocol transparent transmission order of administrative staff's configuration or network management device transmission.For instance, the MAC Address that comprises in the order of two-layer protocol transparent transmission is 0180-C200-0000, corresponding GMAC address is 0100-0000-0001, corresponding interface identifier is the interface identifier of interface 1, then switch 1 will dispose the corresponding relation of MAC Address 0180-C200-0000 and GMAC address 0100-0000-0001 on interface 1, and the corresponding relation of the interface identifier of GMAC address 0100-0000-0001 and interface 1 added transmit, so the GMAC address is that the forwarding interface of message in switch 1 of 0100-0000-0001 is: interface 1.Transmit the logon message that after upgrading generation is carried this GMAC address 0100-0000-0001, finish after the message registration, will send logon message to switch 2.
After switch 2 receives logon message from interface 1, with the GMAC address 0100-0000-0001 in this logon message and receive the interface identifier of the interface of this logon message, the corresponding relation of interface identifier that is the interface 1 of GMAC address 0100-0000-0001 and switch 2 adds in the transmitting of switch 2, makes that the GMAC address is that the forwarding interface of message in switch 2 of 0100-0000-0001 is: interface 1.Finish after the message registration, switch 2 will be transmitted logon message to switch 3 and switch 4 from interface 2 and interface 3.
Switch 3 and switch 4 receive after the logon message, will finish message registration, make that promptly the GMAC address is that the forwarding interface of message in switch 3 of 0100-0000-0001 is interface 1, and the forwarding interface in switch 4 is an interface 2.
Switch 3 and switch 4 are finished after the message registration, have just finished the message registration of the switch on the path of two layers of control protocol message transmission that lead to switch A.Message registration for the switch on the path of realizing leading to switch b, switch 3 will obtain the order of two-layer protocol transparent transmission, the MAC Address that comprises in this two-layer protocol transparent transmission order is 0180-C200-0000, corresponding GMAC address is 0100-0000-0001, and corresponding interface identifier is the interface identifier of interface 2.Logon message will generate in switch 3, to send to switch 2 after finishing the message registration, switch 2 is finished after the message registration, logon message is transmitted to switch 1 and 4, switch 1 and 4 has been finished after the message registration, can realize that STP BPDUs carries out transparent transmission by the corresponding interface in transmitting between switch A and the B.Wherein, the corresponding relation of GMAC address 0100-0000-0001 and interface was as follows during each switch was transmitted:
The forwarding interface of GMAC address 0100-0000-0001 is in the switch 1: interface 1, interface 2;
The forwarding interface of GMAC address 0100-0000-0001 is in the switch 2: interface 1, interface 2;
The forwarding interface of GMAC address 0100-0000-0001 is in the switch 3: interface 1, interface 2;
The forwarding interface of GMAC address 0100-0000-0001 is in the switch 4: interface 2.
Switch is finished after the registration, if switch A sends STP BPDUs to switch b, switch 1 will receive STP BPDUs by interface 1, and with MAC Address 0180-C200-0000 in the STP BPDUs, be converted to corresponding GMAC address 0100-0000-0001, in the transmitting of switch 1, be interface 1 to the corresponding interface of forwarding interface sign of this STP BPDUs according to the GMAC address search, interface 2, because switch can not transmitted STP BPDUs from the interface that receives STP BPDUs, therefore switch 1 will be transmitted STP BPDUs to switch 2 from interface 2, switch 2 is after interface 1 receives STP BPDUs, to obtain the corresponding interface of forwarding interface sign from transmit is interface 1 and interface 2, because switch 2 can not transmitted the STP BPDUs that receives from interface 1 again from interface 1, therefore switch 2 will be transmitted STP BPDUs from interface 2, in like manner, the switch 3 that receives STP BPDUs from interface 1 will be transmitted STP BPDUs to switch B from interface 2, finish the purpose of switch A to switch b transparent transmission STP BPDUs.
Need to prove that though the interface of the interface identifier correspondence of this STP is an interface 2 in the switch 4, because switch 2 can not transmitted STP BPDUs from interface 3, so switch 4 does not still receive this STP BPDUs.
2) when can be when transmitting the transparent transmission of finishing STP between the switch A of user network, B, the C, if the GMAC of this STP is 0100-0000-0001, the interface that each switch is transmitted STP BPDUs in the carrier network be respectively:
The forwarding interface of GMAC address 0100-0000-0001 is in the switch 1: interface 1, interface 2;
The forwarding interface of GMAC address 0100-0000-0001 is in the switch 2: interface 1, interface 2, interface 3;
The forwarding interface of GMAC address 0100-0000-0001 is in the switch 3: interface 1, interface 2;
The forwarding interface of GMAC address 0100-0000-0001 is in the switch 4: interface 1, interface 2.
When switch C does not need carrier network transparent transmission STP agreement, switch 4 will obtain the registration revocation order, the MAC Address of STP in the registration revocation order is 0180-C200-0000, corresponding GMAC address is 0100-0000-0001, interface identifier is the interface identifier of interface 1, switch will be according to the MAC Address 0180-C200-0000 of configuration on the registration revocation order delete interface 1 and the corresponding relation of GMAC address 0100-0000-0001, and the interface identifier of interface 1 deleted from the interface identifier of this GMAC address correspondence, switch 4 deletions are transmitted after the interface 1 of middle GMAC address correspondence, the GMAC address will be only corresponding interface 2, when the interface of this GMAC address correspondence in the switch 4 is no more than 1, switch 4 generates and carries the registration revocation message of GMAC address, and send the registration revocation messages to switch 2 from interface 2, switch 2 will receive in the forwarding interface of interface identifier GMAC address 0100-0000-0001 from transmit of interface 3 of registration revocation message and delete, make that the forwarding interface of GMAC address 0100-0000-0001 becomes in the switch 2: interface 1, interface 2, surpass 1 owing to transmit the interface of STP BPDUs in the switch 2, so switch 2 will stop the registration revocation message forwarding.After the registration revocation message forwarding stops, switch C will no longer participate in the transparent transmission of STP BPDUs.The interface that each switch in the carrier network is transmitted this STP agreement is:
The forwarding interface of GMAC address 0100-0000-0001 is in the switch 1: interface 1, interface 2;
The forwarding interface of GMAC address 0100-0000-0001 is in the switch 2: interface 1, interface 2;
The forwarding interface of GMAC address 0100-0000-0001 is in the switch 3: interface 1, interface 2;
The forwarding interface of GMAC address 0100-0000-0001 is in the switch 4: interface 2.
