Embodiment
To make the object, technical solutions and advantages of the present invention clearer, the present invention is made below in conjunction with the accompanying drawings further
Detailed description.
In embodiment of the present invention, if interchanger has added the end of the VLAN corresponding to VLAN marks with least two
Mouthful, the interchanger is VLAN effective transmission node；If interchanger has been added without at least two and identified corresponding to VLAN
VLAN port, then the interchanger be VLAN failed transmission node.
Fig. 1 is the method flow diagram for suppressing MVRP registration messages according to embodiment of the present invention, and this method is applied to first
Interchanger.
As shown in figure 1, this method includes：
Step 101：The first MVRP registrations that second switch is sent, carrying VLAN marks are received by the first link to disappear
Breath, wherein in second switch have at least two added corresponding to the VLAN mark VLAN port, and second hand over
The port that the first MVRP registration messages are sent on the first link change planes without the VLAN added corresponding to VLAN marks.
Second switch has added the port of the VLAN corresponding to VLAN marks, therefore second switch with least two
For effective transmission node of the VLAN.Second switch is sent by the port added corresponding to the VLAN of VLAN marks and carried
First MVRP registration messages of VLAN marks, and end of the second switch also by not adding the VLAN corresponding to VLAN marks
Mouth sends the first MVRP registration messages for carrying VLAN marks.Wherein, do not added in second switch corresponding to VLAN marks
VLAN port is on the first link.
Herein, the first interchanger receives the first MVRP registration messages of second switch transmission by the first link.Should
The type of message of first MVRP registration messages is Join message.Specifically, Join message may be embodied as JoinEmpty message or
JoinIn message.
Step 102：When the first interchanger of judgement does not have static configuration to correspond to VLAN for leaf node and the first interchanger
During the VLAN of mark, sent by the first chain road direction second switch and suppress message, suppressed message and be used to indicate second switch
The port that the first MVRP registration messages are sent on the first link suppresses to send the first MVRP registration messages.
Herein, when there was only the enabled MVRP ports of one on the first interchanger, assert itself to be leaf node, and
When do not have on the first interchanger static configuration correspond to VLAN mark VLAN when, judge the first interchanger by the first link from
The first MVRP registration messages received by second switch need to be suppressed.Now, the first interchanger passes through the first chain road direction
Second switch, which is sent, suppresses message, and the suppression message is used to indicate that second switch sends the first MVRP notes on the first link
The port of volume message suppresses to send the first MVRP registration messages.
Preferably, the type of message for suppressing message leaves (Leave) message for MVRP, wherein in MVRP Leave message
Have in reserved field and be used to identify the flag for suppressing message.The priority for the flag for suppressing message can be will be used to identify that
It is set below the priority of MVRP Leave message identifiers position.If the interchanger in the network architecture does not support that the present invention is carried
Go out MVRP registration messages and suppress function, then receive after suppressing message, can also will suppress message and be considered as common MVRP
Leave message.
For example the flag A for suppressing message for identifying is set in the reserved field of MVRP Leave message, work as mark
When position A values are 1, represent that enabled MVRP registration messages suppress function；When flag A values are 0, non-enabled MVRP notes are represented
Volume message suppresses function.In addition, there is MVRP Leave message identifiers position B in MVRP Leave message, when flag B values
For 1 when, represent enabled Leave functions；When flag B values are 0, non-enabled Leave functions are represented；Wherein flag B's
Priority is more than flag A priority.
Specifically：
(1), when flag B values are 1, and flag A values are 0, show that the MVRP Leave message is served only for
Leave functions；
(2), when flag B values are 1, and flag A values are 1, show that the MVRP Leave message is served only for
Leave functions；
(3), when flag B values are 0, and flag A values are 1, show that the MVRP Leave message is not used in
Leave functions, but suppress function for MVRP registration messages；
(4), when flag B values are 0, and flag A values are 0, show that the MVRP Leave message did not both have to
In Leave functions, suppress function without in MVRP registration messages.
Second switch sends the first MVRP registrations after the first interchanger receives suppression message on the first link
The port of message suppresses to send the first MVRP registration messages, and other ports for not receiving suppression message keep constant, continue just
Often send the first MVRP registration messages.
Specifically, second switch can send the port raising first of the first MVRP registration messages on the first link
In the transmission cycle of MVRP registration messages, suppress to send first to send the port of the first MVRP registration messages on the first link
MVRP registration messages.For example the transmission cycle of MVRP registration messages is usually 10s, second switch can be by the first link
The first MVRP registration messages transmission period modulation for sending the port of the first MVRP registration messages is 1800s.
The exemplary method in the transmission cycle of the first MVRP registration messages of adjustment, this area are described with specific numeral above
Technical staff it is to be appreciated that do not had to based on concrete application environment and demand, the transmission cycle of the first MVRP registration messages
Adjusted value can also be changed, and embodiment of the present invention is not limited this.
In one embodiment：
After the first interchanger sends suppression message by the first chain road direction second switch, if it is decided that first exchanges
Static configuration corresponds to the VLAN of VLAN marks on machine, and the first interchanger is sent by the first chain road direction second switch and taken
The 2nd MVRP registration messages with VLAN marks, the 2nd MVRP registration messages are used to indicate second switch in the first link
The port derepression for sending the first MVRP registration messages sends the first MVRP registration messages.
Second switch sends first after the first interchanger receives the 2nd MVRP registration messages on the first link
The port derepression of MVRP registration messages sends the first MVRP registration messages.Second switch can be sent on the first link
The ports of first MVRP registration messages reduces the transmission cycle of the first MVRP registration messages, to send the in the port derepression
One MVRP registration messages.Such as, it is assumed that the first MVRP registrations that the port of the first MVRP registration messages is sent on the first link disappear
The breath transmission cycle is adjusted to 1800s from 10s, after second switch receives the 2nd MVRP registration messages, will can send
The first MVRP registration messages transmission cycle of the port is adjusted to 10s again by 1800s.
In one embodiment：
When it is not leaf node that the first interchanger, which judges itself, the first MVRP notes are received by removing on the first link
Port outside the port of volume message sends the first MVRP registration messages.Herein, it is more than one when having on the first interchanger
Enabled MVRP ports when, assert itself not to be leaf node, now the first interchanger need not actively to source interchanger send
Suppress message, but the first MVRP registration messages are received to the port of the first MVRP registration messages by removing on the first link
Outside port.
Fig. 2 is the method flow diagram for suppressing MVRP registration messages according to embodiment of the present invention, and this method is applied to second
Interchanger.
As shown in Fig. 2 this method includes：
Step 201：Receive the first MVRP registration messages for carrying VLAN marks.
Herein, second switch receives the first MVRP registration messages for carrying VLAN marks from other interchangers.This
The type of message of one MVRP registration messages is Join message.Specifically, Join message may be embodied as JoinEmpty message or
JoinIn message.
Step 202：By no port for adding the VLAN for corresponding to VLAN marks to the first link where the port
On as leaf node the first interchanger send the first MVRP registration messages.
Second switch is sent by the port added corresponding to the VLAN of VLAN marks and carries the first of VLAN marks
MVRP registration messages, and second switch is also sent by no port for adding the VLAN for corresponding to VLAN marks and carried
First MVRP registration messages of VLAN marks.Herein, the port corresponding to the VLAN of VLAN marks is not added in the first chain
Lu Shang, and the first interchanger enables as the leaf node on the first link that is, on the first interchanger without more than one
MVRP ports.
Step 203：First interchanger is received by the first link and is receiving the first MVRP registration messages and determination
Itself non-static configuration corresponds to the suppression message sent during the VLAN of VLAN marks.
Herein, when there is no static configuration to correspond to the VLAN that VLAN is identified on the first interchanger, judge that first exchanges
The first MVRP registration messages received by machine from second switch are the repressed MVRP registration messages of needs.Now, first
Interchanger is sent by the first chain road direction second switch suppresses message.Preferably, suppress the type of message of message for MVRP from
(Leave) message is opened, is used to identify the flag for suppressing message wherein in the reserved field of MVRP Leave message having.
Step 204：When the end for judging there are at least two VLAN added corresponding to VLAN marks in second switch
During mouth, suppress to send the first MVRP registration messages according to port of the message on the first link is suppressed.
Herein, after second switch receives the suppression message that the first interchanger is sent by the first link, when sentencing
When determining to have added the port corresponding to the VLAN of VLAN marks with least two in second switch, assert that second switch is
VLAN effective transmission node, suppress to send the first MVRP registration messages according to port of the message on the first link is suppressed, and
Other do not receive port holding the first MVRP registration messages of constant transmission for suppressing message.For example second switch can be
The transmission cycle of the first MVRP registration messages is improved in the port that the first MVRP registration messages are sent on one link, with the first link
The upper port for sending the first MVRP registration messages suppresses to send the first MVRP registration messages.
In one embodiment：
When judging to only have in second switch a port added corresponding to the VLAN of VLAN marks, second is assert
Interchanger is VLAN failed transmission node, and now second switch receives the end for suppressing message by removing on the first link
Port outside mouthful, which is sent, suppresses message, will suppress effective transmission node of the message transmission to VLAN, and by effective transmission
Node suppresses the first MVRP registration messages of transmission in the port of the first link according to message is suppressed.
In one embodiment：
The port that is sent on the first link suppresses after sending the first MVRP registration messages, when second switch passes through the
When one link receives the 2nd MVRP registration messages of the carrying of the first interchanger transmission VLAN marks, on the first link
Port derepression sends the first MVRP registration messages.For example second switch can reduce by the in the port on the first link
The transmission cycle of one MVRP registration messages, to send the first MVRP registration messages in the port derepression.
Embodiment of the present invention is described in more detail with reference to specific networking.Fig. 3 is to be implemented according to the present invention one
The MVRP networking schematic diagrams of mode.
In networking structure shown in Fig. 3, in order to get through VLAN 10 between interchanger C and interchanger F, it is necessary to exchange
On machine C and interchanger F respectively static configuration VLAN 10 and it is two-way between interchanger C and interchanger F get through the passages of VLAN 10,
Specifically include：
The static configuration VLAN 10 on interchanger C, then the port P1 and and interchanger that interchanger C is connected with main frame 1
Port P2 connected B adds VLAN 10.Interchanger C port P2 sends the MVRP registration messages for the mark for carrying VLAN 10
(Join message) arrives the port P1 of switch b.The port P1 of switch b receives the MVRP registration messages, and the end of switch b
Mouth P1 dynamic learnings add VLAN 10, and switch b also sends the MVRP registration messages to the port of switch A by port P2
P1.The port P1 of switch A receives the MVRP registration messages, and the port P1 dynamic learnings of switch A add VLAN 10,
Switch A also sends the MVRP registration messages to interchanger D port P1 by port P2.Interchanger D port P1 is received should
MVRP registration messages, and interchanger D port P1 dynamic learnings add VLAN 10, and interchanger D is also sent by port P2 should
Port P1 of the MVRP registration messages to interchanger F.Interchanger F is due to static configuration VLAN 10, therefore receive MVRP notes
Do not processed after volume message.
The static configuration VLAN 10 on interchanger F, then the port P2 and and interchanger that interchanger F is connected with main frame 2
Port P1 connected D adds VLAN 10.Interchanger F port P1 sends the MVRP registration messages for the mark for carrying VLAN 10
To interchanger D port P2.Interchanger D port P2 receives the MVRP registration messages, and interchanger D port P2 dynamics
Practise and add VLAN 10, interchanger D also sends the MVRP registration messages to the port P2 of switch A by port P1.Switch A
Port P2 receive the MVRP registration messages, and the port P2 dynamic learnings of switch A add VLAN 10, and switch A is also logical
Cross port P1 and send the MVRP registration messages to the port P2 of switch b.The port P2 of switch b receives MVRP registrations and disappeared
Breath, and the port P2 dynamic learnings of switch b add VLAN 10, and switch b also sends MVRP registrations by port P1 and disappeared
Cease interchanger C port P2.Interchanger C is due to static configuration VLAN 10, therefore after receiving MVRP registration messages
Do not process.
It can be seen that as interchanger C and interchanger F difference static configuration VLAN 10, the friendship between interchanger C and interchanger F
The change planes port of (switch b, switch A and interchanger D) can be learnt by MVRP protocol dynamics and add VLAN10, therefore
Two-way between interchanger C and interchanger F it can get through the passages of VLAN 10.
If interchanger G does not have static configuration VLAN 10, then interchanger G will not send carrying VLAN10 mark
MVRP registration messages, so the E of interchanger D port P3 and interchanger P2 is not added in VLAN 10, therefore interchanger C
The passages of VLAN 10 between (or interchanger F) and interchanger G do not have two-way get through.However, interchanger D port P1 and
P2 adds VLAN10, and the MVRP registrations that interchanger D port P3 still can periodically send carrying VLAN 10 mark disappear
Breath, and interchanger E P1 ports and interchanger G P1 ports can all add VLAN10.However, for interchanger D and exchange
For link between machine G, the MVRP registration messages are that needs are repressed.
In processing mode in the prior art, when interchanger E and interchanger G receives periodic MVRP registration messages
When, these MVRP registration messages of respective cyclical process are two-way due to not getting through VLAN between interchanger D and interchanger G
Passage, vlan traffic is not flowed through between interchanger E and interchanger G, it is not significant to handle these MVRP registration messages, therefore
Unnecessary cpu resource is caused to waste.
Fig. 4 is the source suppressing method flow chart of networking shown in Fig. 3 according to embodiment of the present invention.
As shown in figure 4, this method includes：
Step 401：Interchanger E port P1 from the interchanger D of effective transmission node as VLAN10 port P3 connect
The first MVRP registration messages of the mark for carrying VLAN 10 are received, interchanger E port P1 dynamic learnings simultaneously add VLAN 10.Hand over
The E that changes planes has found itself there is more than one enabled MVRP ports (i.e. port P1 and P2), therefore, it is determined that itself is not leaf section
Point, now interchanger E the first MVRP registration messages are sent by port P2.
Step 402：After interchanger G P1 ports receive the first MVRP registration messages from interchanger E port P2, hand over
Change planes G port P1 dynamic learnings and add VLAN 10.Interchanger G has found itself there was only an enabled MVRP port (i.e. port
P1), therefore, it is determined that itself is leaf node.Moreover, interchanger G has found itself do not have static configuration VLAN 10, therefore, it is determined that the
One MVRP registration messages are that needs are repressed.Now, interchanger G is sent to interchanger E port P2 by port P1 and suppressed
Message.
Step 403:Interchanger E port P2, which is received, suppresses message, finds itself only have a port to add VLAN 10
(i.e. port P1), then assert the failed transmission node that interchanger E is VLAN 10, therefore message will be suppressed by port P1 and sent
Interchanger D port P3.
Step 404:Interchanger D port P3 receives from interchanger E port P1 suppresses message, it is found that itself has two
VLAN 10 port (port P1 and port P2) is added, assert effective transmission node that interchanger D is VLAN 10, therefore basis
Suppress message to suppress to send the first MVRP registration messages in port P3, so as to mitigate interchanger E and interchanger G burden.
Step 405：When in static configuration VLAN 10 on interchanger G, interchanger G is by port P1 to interchanger E end
Mouth P2 sends the 2nd MVRP registration messages of the mark for carrying VLAN 10.
Step 406：Interchanger E port P2 receives the 2nd MVRP registration messages, and P2 ports are dynamically added VLAN 10, and
And interchanger E sends the 2nd MVRP registration messages by port P1 to interchanger D port P3.
Step 407：Interchanger D port P3 receives the 2nd MVRP registration messages, and P3 ports are dynamically added VLAN 10, and
And send the first MVRP registration messages in interchanger D port P3 derepressions.
Based on above-mentioned analysis, Fig. 5 is the structure drawing of device for suppressing MVRP registration messages according to embodiment of the present invention, should
