Embodiment
For making the object, technical solutions and advantages of the present invention clearly, below in conjunction with accompanying drawing, the present invention is described in further detail.
In embodiment of the present invention, if switch has the port that at least two have added the VLAN corresponding to VLAN mark, this switch is effective transmission node of VLAN; If switch does not have the port that at least two have added the VLAN corresponding to VLAN mark, then this switch is the failed transmission node of VLAN.
Fig. 1 is according to embodiment of the present invention, and suppress the method flow diagram of MVRP registration message, the method is applied to the first switch.
As shown in Figure 1, the method comprises:
Step 101: receive a MVRP registration message that the second switch sends, that carry VLAN mark by the first link, wherein the second switch has the port that at least two have added the VLAN identified corresponding to this VLAN, and the second switch port of sending a MVRP registration message on the first link does not add the VLAN corresponding to VLAN mark.
Second switch has the port that at least two have added the VLAN corresponding to VLAN mark, and therefore the second switch is effective transmission node of this VLAN.Second switch sends by the port added corresponding to the VLAN of VLAN mark the MVRP registration message carrying VLAN mark, and the second switch also sends by the port do not added corresponding to the VLAN of VLAN mark the MVRP registration message carrying VLAN mark.Wherein, the second switch does not add the port of the VLAN identified corresponding to VLAN on the first link.
Here, the first switch receives a MVRP registration message of the second switch transmission by the first link.The type of message of the one MVRP registration message is Join message.Particularly, Join message may be embodied as JoinEmpty message or JoinIn message.
Step 102: when judge the first switch as leaf node and the first switch do not have static configuration correspond to VLAN mark VLAN time, sent by the first chain road direction second switch and suppress message, suppression message is used to indicate port suppression transmission the one MVRP registration message that the second switch sends a MVRP registration message on the first link.
Here, when the first switch only having the enable MVRP port of, assert certainly as leaf node, and when the first switch not having static configuration correspond to the VLAN of VLAN mark, judge that the first switch needs suppressed by the first link from the MVRP registration message received by the second switch.Now, the first switch is sent by the first chain road direction second switch and suppresses message, and this suppression message is used to indicate port suppression transmission the one MVRP registration message that the second switch sends a MVRP registration message on the first link.
Preferably, the type of message suppressing message is that MVRP leaves (Leave) message, wherein has in the reserved field of MVRPLeave message for identifying the flag suppressing message.The priority being used for the flag identifying suppression message can be set to the priority lower than MVRP Leave message identifier position.If the switch in the network architecture does not support MVRP registration message inhibit feature proposed by the invention, so receive after suppressing message, also suppression message can be considered as common MVRP Leave message.
Such as, setting in the reserved field of MVRP Leave message for identifying the flag A suppressing message, when flag A value is 1, representing enable MVRP registration message inhibit feature; When flag A value is 0, represent disable MVRP registration message inhibit feature.In addition, there is in MVRP Leave message MVRP Leave message identifier position B, when flag B value is 1, represent enable Leave function; When flag B value is 0, represent disable Leave function; Wherein the priority of flag B is greater than the priority of flag A.
Particularly:
(1), when flag B value is 1, and when flag A value is 0, show that this MVRP Leave message is only for Leave function;
(2), when flag B value is 1, and when flag A value is 1, show that this MVRP Leave message is only for Leave function;
(3), when flag B value is 0, and when flag A value is 1, show that this MVRP Leave message is not used in Leave function, but for MVRP registration message inhibit feature;
(4), when flag B value is 0, and when flag A value is 0, shows that this MVRP Leave message had both been not used in Leave function, be also not used in MVRP registration message inhibit feature.
Second switch receives from the first switch and suppresses after message, the port that first link sends a MVRP registration message suppresses transmission the one MVRP registration message, and other ports not receiving suppression message remain unchanged, continue normal transmission the one MVRP registration message.
Particularly, the second switch can send the transmission cycle of port raising the one MVRP registration message of a MVRP registration message on the first link, suppresses transmission the one MVRP registration message with the port sending a MVRP registration message on the first link.Such as, the transmission cycle of MVRP registration message is generally 10s, and it is 1800s that a MVRP registration message of the port the first link sending a MVRP registration message can be sent period modulation by the second switch.
The exemplary method in the transmission cycle of adjustment the one MVRP registration message is described above with concrete numeral, those skilled in the art can recognize, based on embody rule environment and demand need not, the adjusted value in the transmission cycle of the one MVRP registration message also can change, and embodiment of the present invention does not limit this.
In one embodiment:
After the first switch sends suppression message by the first chain road direction second switch, if it is determined that static configuration corresponds to the VLAN of VLAN mark on the first switch, first switch sends the 2nd MVRP registration message carrying this VLAN and identify by the first chain road direction second switch, the 2nd MVRP registration message is used to indicate port derepression transmission the one MVRP registration message that the second switch sends a MVRP registration message on the first link.
Second switch is from after the first switch receives the 2nd MVRP registration message, and the port derepression that the first link sends a MVRP registration message sends a MVRP registration message.Second switch can send the transmission cycle of port reduction the one MVRP registration message of a MVRP registration message on the first link, to send a MVRP registration message at this port derepression.Such as, assuming that the MVRP registration message the first link sending the port of a MVRP registration message sends the cycle be adjusted to 1800s from 10s, after second switch receives the 2nd MVRP registration message, the cycle that the MVRP registration message sending this port can be sent is adjusted to 10s again by 1800s.
In one embodiment:
When the first switch judges self not as leaf node, send a MVRP registration message by the port except the port of reception the one MVRP registration message on the first link.Here, when the first switch having more than one enable MVRP port, assert self not to be leaf node, now the first switch does not need initiatively to send to source switch to suppress message, but by a MVRP registration message by the port except the port of reception the one MVRP registration message on the first link.
Fig. 2 is according to embodiment of the present invention, and suppress the method flow diagram of MVRP registration message, the method is applied to the second switch.
As shown in Figure 2, the method comprises:
Step 201: receive the MVRP registration message carrying VLAN mark.
Here, the second switch receives the MVRP registration message carrying VLAN mark from other switch.The type of message of the one MVRP registration message is Join message.Particularly, Join message may be embodied as JoinEmpty message or JoinIn message.
Step 202: send a MVRP registration message by first switch of port as leaf node on first link at this port place do not added corresponding to the VLAN of VLAN mark.
Second switch sends by the port added corresponding to the VLAN of VLAN mark the MVRP registration message carrying VLAN mark, and the second switch also sends by the port do not added corresponding to the VLAN of VLAN mark the MVRP registration message carrying VLAN mark.Here, do not add the port of the VLAN identified corresponding to VLAN on the first link, and the first switch is as the leaf node on the first link, namely the first switch does not have more than one enable MVRP port.
Step 203: receive the first switch receiving a described MVRP registration message and determine the suppression message that self non-static configuration sends when corresponding to the VLAN of described VLAN mark by the first link.
Here, when the first switch not having static configuration correspond to the VLAN of VLAN mark, judge the first switch from the MVRP registration message received by the second switch as the repressed MVRP registration message of needs.Now, the first switch is sent by the first chain road direction second switch and suppresses message.Preferably, the type of message suppressing message is that MVRP leaves (Leave) message, wherein has in the reserved field of MVRP Leave message for identifying the flag suppressing message.
Step 204: when judgement second switch having at least two and having added the port of the VLAN identified corresponding to VLAN, suppress transmission the one MVRP registration message according to the port suppressing message on the first link.
Here, after second switch receives the suppression message of the first switch transmission by the first link, when judgement second switch having at least two and having added the port of the VLAN identified corresponding to VLAN, assert that the second switch is effective transmission node of VLAN, according to suppressing the port of message on the first link to suppress transmission the one MVRP registration message, and other do not receive and suppress ports of message to remain unchanged transmission the one MVRP registration message.Such as, the second switch can send the transmission cycle of port raising the one MVRP registration message of a MVRP registration message on the first link, suppresses transmission the one MVRP registration message with the port sending a MVRP registration message on the first link.
In one embodiment:
During the port added corresponding to the VLAN of VLAN mark when judgement second switch only having, assert that the second switch is the failed transmission node of VLAN, now the second switch is sent by the port except receiving the port suppressing message on the first link and suppresses message, with the effective transmission node that will Message Transmission suppressed to VLAN, and suppress transmission the one MVRP registration message by this effective transmission node according to the port suppressing message at the first link.
In one embodiment:
After the port that first link sends suppresses transmission the one MVRP registration message, when the second switch by the first link receive that the first switch sends carry the 2nd MVRP registration message that this VLAN identifies time, port derepression on the first link sends a MVRP registration message.Such as, the second switch port on the first link can reduce transmission cycle of a MVRP registration message, to send a MVRP registration message at this port derepression.
Below in conjunction with concrete networking, embodiment of the present invention is described in more detail.Fig. 3 is MVRP networking schematic diagram according to an embodiment of the present invention.
In networking structure shown in Fig. 3, in order to get through VLAN 10 between switch C and switch F, to need on switch C and switch F static configuration VLAN 10 two-wayly between switch C and switch F get through VLAN 10 passage respectively, specifically comprising:
Static configuration VLAN 10 on switch C, so the port P1 that is connected with main frame 1 of switch C and the port P2 that is connected with switch b adds VLAN 10.The port P1 of MVRP registration message (Join message) to switch b of the mark of VLAN 10 is carried in the port P2 transmission of switch C.The port P1 of switch b receives this MVRP registration message, and the port P1 dynamic learning of switch b adds VLAN 10, and switch b also sends the port P1 of this MVRP registration message to switch A by port P2.The port P1 of switch A receives this MVRP registration message, and the port P1 dynamic learning of switch A adds VLAN 10, and switch A also sends the port P1 of this MVRP registration message to switch D by port P2.The port P1 of switch D receives this MVRP registration message, and the port P1 dynamic learning of switch D adds VLAN 10, and switch D also sends the port P1 of this MVRP registration message to switch F by port P2.Switch F, due to static configuration VLAN 10, does not process after therefore receiving MVRP registration message.
Static configuration VLAN 10 on switch F, so the port P2 that is connected with main frame 2 of switch F and the port P1 that is connected with switch D adds VLAN 10.The port P2 of MVRP registration message to switch D of the mark of VLAN 10 is carried in the port P1 transmission of switch F.The port P2 of switch D receives this MVRP registration message, and the port P2 dynamic learning of switch D adds VLAN 10, and switch D also sends the port P2 of this MVRP registration message to switch A by port P1.The port P2 of switch A receives this MVRP registration message, and the port P2 dynamic learning of switch A adds VLAN 10, and switch A also sends the port P2 of this MVRP registration message to switch b by port P1.The port P2 of switch b receives this MVRP registration message, and the port P2 dynamic learning of switch b adds VLAN 10, and switch b also sends the port P2 of this MVRP registration message to switch C by port P1.Switch C, due to static configuration VLAN 10, does not process after therefore receiving MVRP registration message.
Visible, as switch C and switch F difference static configuration VLAN 10, the port of the switch (switch b, switch A and switch D) between switch C and switch F can be learnt by MVRP protocol dynamic and add VLAN10, therefore two-wayly between switch C and switch F can get through VLAN 10 passage.
If switch G does not have static configuration VLAN 10, so switch G can not send the MVRP registration message of the mark of carrying VLAN10, so the P2 of the port P3 of switch D and the E of switch does not add in VLAN 10, VLAN 10 passage therefore between switch C (or switch F) and switch G is not two-way to be got through.But port P1 and P2 of switch D all adds VLAN10, the port P3 of switch D still periodically can send the MVRP registration message of the mark of carrying VLAN 10, and the P1 port of switch E and the P1 port of switch G all can add VLAN10.But for the link between switch D and switch G, this MVRP registration message is that needs are repressed.
In processing mode in the prior art, when switch E and switch G receives periodic MVRP registration message, these MVRP registration messages of respective cyclical process, owing to not getting through VLAN duplex channel between switch D and switch G, vlan traffic can not be flowed through between switch E and switch G, process these MVRP registration messages and do not have meaning, therefore cause unnecessary cpu resource waste.
Fig. 4 is according to embodiment of the present invention, the source suppressing method flow chart of networking shown in Fig. 3.
As shown in Figure 4, the method comprises:
Step 401: the port P1 of switch E receives from the port P3 of the switch D of the effective transmission node as VLAN10 the MVRP registration message carrying the mark of VLAN 10, the port P1 dynamic learning of switch E also adds VLAN 10.Switch E finds self to have more than one enable MVRP port (i.e. port P1 and P2), therefore judges self not as leaf node, and now a MVRP registration message is sent by port P2 by switch E.
Step 402: after the P1 port of switch G receives a MVRP registration message from the port P2 of switch E, the port P1 dynamic learning of switch G also adds VLAN 10.Switch G finds self to only have an enable MVRP port (i.e. port P1), therefore judges certainly as leaf node.And switch G finds self do not have static configuration VLAN 10, therefore judge that a MVRP registration message is that needs are repressed.Now, switch G is by the port P2 transmission suppression message of port P1 to switch E.
Step 403: the port P2 of switch E receives and suppresses message, find self to only have a port to add VLAN 10 (i.e. port P1), then assert that switch E is the failed transmission node of VLAN 10, therefore will be suppressed the port P3 of message transmission switch D by port P1.
Step 404: the port P3 of switch D receives from the port P1 of switch E and suppresses message, find that self there is the port (port PA and port P2) that two add VLAN 10, assert that switch D is effective transmission node of VLAN 10, therefore suppress transmission the one MVRP registration message according to suppression message at port P3, thus alleviate the burden of switch E and switch G.
Step 405: when on switch G during static configuration VLAN 10, switch G sends to the port P2 of switch E the 2nd MVRP registration message carrying the mark of VLAN 10 by port P1.
Step 406: the port P2 of switch E receives the 2nd MVRP registration message, and P2 port dynamically adds VLAN 10, and switch E is by the port P3 transmission two MVRP registration message of port P1 to switch D.
Step 407: the port P3 of switch D receives the 2nd MVRP registration message, and P3 port dynamically adds VLAN 10, and send a MVRP registration message at the port P3 derepression of switch D.
