In the relevant technologies, the basic thought of STP (Spanning Tree Protocl, Spanning-Tree Protocol) agreement be according to
The topological structure of the structure tectonic network of tree.The root of tree can be the equipment of referred to as root bridge, form one step by step by root bridge
Tree.Root bridge can be determined that the equipment of BID minimums becomes two by the BID of interchanger or bridge (Bridge ID, bridge identification code)
Root bridge in layer network.BID can be by bridge priority and Mac (Media Access Control, media access control layer)
Address is formed.The timing of root bridge sends configuration bpdu (Bridge Protocol Data Unit, Bridge Protocol Data Unit), non-
Root bridge joint receives configuration bpdu, refreshes best BPDU and forwards.Wherein, best BPDU can refer to the BPDU transmitted by current root bridge.
If receiving inferior bpdu (equipment newly accessed can send BPDU, but the BID of the equipment is bigger than current root bridge), this is received
The equipment of inferior bpdu will send the best BPDU of oneself storage to the equipment newly accessed, to inform root in its current network
Bridge.If the BPDU received is more excellent, it will recalculates the topological structure of simultaneously tectonic network.
In order to reduce the line of DR equipment rooms in DR systems, it is proposed the DRNI networkings of no Peer-Link.Fig. 2 shows phases
The schematic diagram of the DRNI networkings without Peer-Link in the technology of pass.As shown in Fig. 2, device A and equipment B are DR equipment, equipment C
It is external equipment with equipment D.Device A and equipment B form DR systems, but the link not being directly connected between device A and equipment B.
Tunnel, such as VXLAN tunnels can be established between device A and equipment B.The tunnel face of device A and equipment B can be used as IPP mouthfuls, if
Link where standby tunnel between A and equipment B can be used as IPL links, pass through IPL links between device A and equipment B to realize
Transmit DRCP messages.The link structure that Keepalive links can then be connect by the gateway mouth of device A and equipment B with interchanger
Into.
As shown in Fig. 2, the process that DR systems are established between device A and equipment B is as follows：Terminal device is regular by IPL links
Send DRCP messages.After the DRCP messages for receiving opposite end, can judge DR interface indexes in DRCP messages whether with local terminal phase
Together.If the DR interface indexes at both ends are identical, this two equipment composition DR systems.After successful matching, terminal device can determine whether
Go out master slave mode.First compare DR device role priority, be worth that smaller priority is higher, and priority is high for main equipment.It is if excellent
First grade is identical, then compares the bridge Mac of two equipment, bridge Mac smaller is main equipment.Terminal device passes through Keepalive chains
Road periodically sends Keepalive messages, when terminal device can receive the Keepalive messages of opposite end transmission,
DRNI networkings start normally to work.After DR system starts, the information of meeting real-time synchronization opposite end between terminal device, such as
Mac list items, ARP entry etc., any one equipment fault in such device A and equipment B all do not interfere with the forwarding of flow, protect
Demonstrate,proving normal business will not interrupt.

The port status setting method of the disclosure, by judging any two senders for carrying the BPDU messages of identical BID
Whether it is same equipment, and in the case where judging sender not for same equipment, makes the end of reception any two BPDU messages
Mouth remains unimpeded state, and thus, it is possible to avoid in the DRNI networkings of no Peer-Link as the tunnel of IPL links by STP
Protocol blocks so as to ensure that IPL links are unimpeded, ensure that DR systems normally effectively work, improve the stability of DR systems.
In one implementation, whether the sender for judging the first BPDU messages and the 2nd BPDU messages is same set
Standby, obtaining judging result (step S32) can include：Judge whether the first BPDU messages and the 2nd BPDU messages carry mark respectively
Know；Judge whether the first BPDU messages and the 2nd BPDU messages carry mark respectively；It is reported in the first BPDU messages and the 2nd BPDU
In the case of literary carrying identifies, and the mark of the first BPDU messages carrying and the mark of the 2nd BPDU messages carrying are different,
The sender for being judged as the first BPDU messages and the 2nd BPDU messages is not same equipment.
In one implementation, it can increase mark in BPDU messages, such as TLV (Type Length Value,
Type lengths values) field.In the case where the BID of any two BPDU messages carrying is identical, the mark in BPDU messages can be passed through
Knowledge judges whether the sender of two BPDU messages is same equipment.It is for example, identical in the BID that any two BPDU messages carry
In the case of, if the mark in the first BPDU messages is identical with the mark in the 2nd BPDU messages, it may determine that the first BPDU
The sender of message and the 2nd BPDU messages is same equipment；If in the mark and the 2nd BPDU messages in the first BPDU messages
Mark differs, then the sender that may determine that the first BPDU messages and the 2nd BPDU messages is not same equipment.
It should be noted that it will be appreciated by those skilled in the art that the mark that the disclosure is not limited in BPDU messages determines
Method, whether the sender that can distinguish any two BPDU messages for carrying identical BID is same equipment.For example, BPDU
Mark in message can determine that DR equipment may be used in the mark that is, in BPDU messages by the DR System Numbers of DR equipment
DR System Numbers are filled.For another example the mark in BPDU messages can be determined by the MAC Address of DR equipment, i.e. BPDU messages
In mark the MAC Address of DR equipment may be used.
Fig. 4 shows the schematic diagram of the DRNI networkings without Peer-Link according to one embodiment of the disclosure.As shown in figure 4, it sets
Standby A and equipment B is DR equipment, and equipment C and equipment D are external equipment.Device A and equipment B form DR systems.But it device A and sets
The link not being directly connected between standby B.Port1 is the physical port of device A, and Port2 is the physical port of equipment B, if Port1
It is configured as tunnel face, tunnel being established between device A and equipment B with Port2.The tunnel face of device A and equipment B can be used as IPP
Mouthful, the link where tunnel between device A and equipment B can be used as IPL links.It is achieved in passing through between device A and equipment B
IPL link transmission DRCP messages.What Keepalive links can then be connect by the gateway mouth of device A and equipment B with interchanger
Link is formed.
In one implementation, according to the judging result, the port of the first BPDU messages and reception second are controlled and received
The state setting (step S33) of the port of BPDU messages can include：It is being judged as the first BPDU messages and the 2nd BPDU messages
Sender it is unequal for the port that in the case of same equipment, receives the first BPDU messages and the port for receiving the 2nd BPDU messages
Remain unimpeded state.
As an example, as shown in figure 4, the DR systems Mac of device A and equipment B can be denoted as Macs, the DR of device A
System Number can be 1, and the DR System Numbers of equipment B can be 2.The Mac of equipment C can be denoted as Macc, and the Mac of equipment D can
To be denoted as Macd, and Macs<Macd<Macc.
As shown in figure 4, since DR systems Mac is less than the bridge Mac of equipment C and equipment D, if DR systems are root bridge, device A
All think it oneself is root bridge with equipment B, BPDU messages can be sent and give equipment D.Equipment D is received by Port3 comes from DR
The BPDU messages 1 of system and the BPDU messages 2 for coming from DR systems by Port4 receptions.Wherein, BPDU messages 1 carry
BID is Macs, is identified as 1.The BID that BPDU messages 2 carry is Macs, is identified as 2.Due to BPDU messages 1 carry BID with
The BID that BPDU messages 2 carry is identical, but the mark in BPDU messages 1 is differed with the mark in BPDU messages 2, and equipment D judges
The sender of BPDU messages 1 and BPDU messages 2 is the different DR equipment of same DR systems, and thus equipment D is by Port3 and Port4
Unimpeded state is remained, the tunnel in the DRNI networkings of no Peer-Link as IPL links can be avoided to be hindered by STP protocol
Plug so as to ensure that IPL links are unimpeded, ensures that DR systems normally effectively work, improves the stability of DR systems.
In one implementation, equipment receives BPDU messages by root port, and BPDU messages are sent by designated port.
When choosing root port, the smaller BPDU messages higher BPDU messages of grade as priority can will be identified.Equipment D is being received
After BPDU messages 1 and BPDU messages 2, the BPDU messages 1 received are found as the higher BPDU messages of priority, by equipment D
Port3 be selected as root port.The BPDU messages 1 that equipment D is received by Port4 forwardings from root port Port3.Equipment B is being received
To after BPDU messages 1, it is found that for the higher BPDU messages of priority, the Port2 of equipment B is selected for the BPDU messages 1 received
For root port, equipment B stops sending BPDU messages to equipment D by Port2.
As an example, as shown in figure 4, the DR systems Mac of device A and equipment B can be denoted as Macs, the DR of device A
System Number can be 1, and the DR System Numbers of equipment B can be 2.The Mac of equipment C can be denoted as Macc, and the Mac of equipment D can
To be denoted as Macd, and Macc<Macs<Macd.
As shown in figure 4, since the bridge Mac of equipment C is less than the bridge Mac of DR systems Mac and equipment D, equipment C is root bridge, then
Equipment C can send BPDU messages to device A and equipment B.Device A and equipment B are respectively received the BPDU reports for coming from equipment C
Text 3.Wherein, the BID that BPDU messages 3 carry is Macc, does not carry mark.The BPDU messages 3 that device A discovery receives are preferential
The higher BPDU messages of grade, thus device A BPDU messages 4 are sent to equipment D by Port1.Wherein, BPDU messages 4 carry
BID is Macc, is identified as 1.The BPDU messages 3 that equipment and B discoveries receive are the higher BPDU messages of priority, thus equipment
B sends BPDU messages 5 by Port2 to equipment D.Wherein, the BID that BPDU messages 5 carry is Macc, is identified as 2.Equipment D leads to
It crosses Port3 and receives the BPDU messages 4 for coming from DR systems and the BPDU messages for coming from DR systems by Port4 receptions
5.Since the BID that BPDU messages 4 carry is identical with the BID that BPDU messages 5 carry, but the mark in BPDU messages 4 is reported with BPDU
Mark in text 5 differs, and equipment D judges that the sender of BPDU messages 4 and BPDU messages 5 sets for the different DR of same DR systems
Standby, thus Port3 and Port4 is remained unimpeded state by equipment D, can avoid making in the DRNI networkings of no Peer-Link
Tunnel for IPL links is blocked by STP protocol, so as to ensure that IPL links are unimpeded, ensures that DR systems normally effectively work, carries
The stability of high DR systems.
Fig. 5 shows the schematic diagram of the DRNI networkings without Peer-Link according to one embodiment of the disclosure.As shown in figure 5, it sets

State.
As an example, as shown in figure 5, the DR systems Mac of device A and equipment B can be denoted as Macs, the DR of device A
System Number can be 1, and the DR System Numbers of equipment B can be 2.The Mac of equipment C can be denoted as Macc, and the Mac of equipment D can
To be denoted as Macd, and Macs<Macd<Macc.
As shown in figure 5, since DR systems Mac is less than the bridge Mac of equipment C and equipment D, if DR systems are root bridge, device A
All think it oneself is root bridge with equipment B, BPDU messages can be sent and give equipment D.Equipment D is received by Port3 comes from DR
The BPDU messages 1 of system, the BPDU messages 2 and being received by Port6 that DR systems are come from by Port4 receptions come from
In the BPDU messages 6 of DR systems.Wherein, the BID that BPDU messages 1 carry is Macs, is identified as 1.The BID that BPDU messages 2 carry
For Macs, it is identified as 2.The BID that BPDU messages 6 carry is Macs, does not carry mark.Due to BPDU messages 1 carry BID with
The BID that BPDU messages 2 carry is identical, but the mark in BPDU messages 1 is differed with the mark in BPDU messages 2, and equipment D judges
The sender of BPDU messages 1 and BPDU messages 2 is the different DR equipment of same DR systems, and thus equipment D is by Port3 and Port4
Unimpeded state is remained, the tunnel in the DRNI networkings of no Peer-Link as IPL links can be avoided to be hindered by STP protocol
Plug so as to ensure that IPL links are unimpeded, ensures that DR systems normally effectively work, improves the stability of DR systems.Since BPDU is reported
The BID that text 2 carries is identical with the BID that BPDU messages 6 carry, but BPDU messages 6 do not carry mark, and equipment D judges BPDU messages 2
Sender with BPDU messages 6 is the same DR equipment of same DR systems, and thus Port4 is remained unimpeded state by equipment D, will
Port6 is set as blocked state, being capable of anti-loops.
The port status setting method of the disclosure is added mark in BPDU messages, is sentenced by the mark in BPDU messages
Whether the sender of any two BPDU messages for carrying identical BID of breaking is same equipment, and is judging that sender do not set to be same
In the case of standby, the port of reception any two BPDU messages is made to remain unimpeded state, thus, it is possible to avoid no Peer-
