Lower step:
Step 1, on duplicated multicast message to the exchange chip of each interchanger for having multicast member port；
Step 2, on the exchange chip duplicated multicast message to the multicast member port of the interchanger.
Specifically, in forwarding multicasting message, needing multicast message being sent to group in distributed system or stacking system
It broadcasts in group, in multicast group, it is understood that there may be trunking group, it is also possible to trunking group, in the present embodiment, described group be not present
Casting text refers to the message that multicast replication is carried out when forwarding, and whether the message including carrying out broadcast replication, be group with message itself
Casting text is unrelated, further, there are for multiple trunking groups, and by taking 3 interchangers as an example, to illustrate point in multicast group
Multicast message processing method in cloth link aggregation network.
As shown in Fig. 2, in the distributed system, including 3 interchangers interconnected, each interchanger include 3
A port and an exchange chip, such as the first interchanger includes port 1-port-1,1-port-2 and 1-port-3, and
First exchange chip, second switch include port 2-port-1,2-port-2 and 2-port-3 and the second exchange chip,
3rd switch includes port 3-port-1,3-port-2 and 3-port-3 and third exchange chip, wherein the first exchange
Port 1-port-2,1-port-3 on machine and the port 2-port-1 in second switch are configured to first port convergence group；
Port 2-port-3 in second switch and the port 3-port-1 in 3rd switch, 3-port-2 are configured to second port
Convergence group, and there are a multicast group mcastGroup1, first port convergence group and second port convergence groups and second to hand over
The port 2-port-2 to change planes is added in multicast group mcastGroup1.
It, will by the first exchange chip after multicast message is from the port 1-port-1 of the first interchanger into the first interchanger
Multicast message copies on the second exchange chip of second switch and on the third exchange chip of 3rd switch, meanwhile,
In first interchanger, multicast message is copied in first port convergence group on the first exchange chip and second port convergence group
In, in second switch, multicast message is copied to first port convergence group on the second exchange chip and second port is converged
It in poly group, while being copied in the 2-port-2 of port, in 3rd switch, multicast message is answered on third exchange chip
It makes in first port convergence group and second port convergence group, wherein the multicast message for copying to port 2-port-2 is normal
It forwards, the multicast message copied in first port convergence group and second port convergence group further does forwarding and checks.
Step 3, the trunking group in multicast group is configured on each interchanger, and each trunking group is in different friendships
The member port configuration sequence changed in chip is consistent, and configures the selection strategy of each trunking group membership port, and every
The member port that trunking group selection in a interchanger goes out is consistent；
Step 4, judge whether the trunking group membership port chosen is port on the interchanger, if so,
Multicast message is sent, otherwise, abandons multicast message.
Specifically, there may be multiple trunking groups in multicast group, the member of each trunking group is needed to configure
Port order is consistent, and first port convergence group is configured in the first interchanger, keeps member port configuration sequence consistent, this reality
It applies in example, it is preferable that the member port sequence of first port convergence group is followed successively by 1-port-2,1-port-3,2-port-1, when
So also the person's of can be configured to port order is followed successively by 2-port-1,1-port-3,1-port-2, while matching in second switch
The member port sequence for setting first port convergence group, is consistent with the first interchanger, be followed successively by 1-port-2,1-port-3,
2-port-1 configures the member port sequence of first port convergence group in 3rd switch, is consistent with the first interchanger,
It is followed successively by 1-port-2,1-port-3,2-port-1.Likewise, on the first interchanger configure second port convergence group at

Port-1,3-port-2 configure the member port sequence of second port convergence group in second switch, keep with the first interchanger
Unanimously, 2-port-3,3-port-1 are followed successively by, 3-port-2 configures the member end of second port convergence group in 3rd switch
Mouth sequence, is consistent with the first interchanger, is followed successively by 2-port-3,3-port-1,3-port-2.
In each trunking group, using the strategy of identical selection member port, it is ensured that identical message is in each friendship
The member port selected in the trunking group changed planes be it is same, such as multicast message enters the of the first interchanger
In one exchange chip, the first exchange chip copies to multicast message in the second exchange chip and in third exchange chip, simultaneously
For duplicated multicast message into first port convergence group and second port convergence group, multicast message is copied to by the second exchange chip
In Single port convergence group and second port convergence group；In the first port convergence group of first exchange chip, if select
Port is 1-port-2, and in the first port convergence group of the second exchange chip, the port selected is similarly 1-port-2, into
Whether the port selected of one step judgement is port on this interchanger, if the port on this interchanger, then by multicast message
It forwards from the port, otherwise, multicast message is abandoned, since 1-port-2 is the port on the first interchanger, because
This multicast message is forwarded away from the port 1-port-2 of the first exchange chip, and is copied to 1- in the second exchange chip
The message of the port port-2 can be dropped.
By the above method, enables to multicast message only to have a message in a port convergence group and be replicated out
It goes.
As shown in figure 3, the exchange chip that the multicast message in a kind of distributed aggregated link network is handled, including message are multiple
Molding block, configuration storage module and message processing module (MPM), the message replication module, which copies to multicast message, each has group

In each trunking group, using the algorithm of identical selection port, it is ensured that converge the port in each interchanger
The port selected in poly group is consistent, and is entered in the first exchange chip of the first interchanger such as a multicast message, and first hands over
Change that chip copies to multicast message in the second exchange chip by the message replication module in the first interchanger and third exchanges
In chip, while duplicated multicast message to first port convergence group neutralizes in second port convergence group, and the second exchange chip is by group
Casting text is copied in first port convergence group and second port convergence group by the message replication module in second switch；?
In the first port convergence group of first exchange chip, if the port selected is 1-port-2, the first of the second exchange chip
In trunking group, the port selected is similarly 1-port-2, in the first port convergence group of third exchange chip, selection
Port out is similarly 1-port-2, the message processing module (MPM) in first interchanger, second switch and 3rd switch
Further judge whether the port selected is port on this interchanger respectively, if the port on this interchanger, then by group
Casting text is forwarded from the port, otherwise, multicast message is abandoned, since 1-port-2 is the end on the first interchanger
Mouthful, therefore multicast message is forwarded away from the port 1-port-2 of the first exchange chip, and copy to the second exchange chip and
The message of the port 1-port-2 can be dropped in third exchange chip.
It is realized in the exchange chip of interchanger, eliminates the physical storage device of multicast segregation table completely, reduce friendship
The design cost of chip is changed, in addition, the relationship of maintenance with multicast is no longer needed to when trunking group adds removing members,
Greatly reduce the implementation complexity and maintenance cost of software；Meanwhile the configuration of trunking group can be shared with unicast, that is, does
The message of unicast forwarding also multiplexing port convergence group configuration and select member port strategy, which ensures that unicasts and multicast
Be for the member port that identical message is selected it is identical, also just accomplished trunking group selection member port and forwarding side
Formula is unrelated.
