The port 2-port-1 on port 1-port-2,1-port-3 and second switch on machine is configured to first port convergence group；
The port 3-port-1 on port 2-port-3 and 3rd switch in second switch, 3-port-2 are configured to second port
Convergence group, and there is multicast group mcastGroup1, first port convergence group and second port convergence group, and second hands over
The port 2-port-2 for changing planes is added in multicast group mcastGroup1.
Multicast message is entered after the first switch from the port 1-port-1 of the first switch, will by the first exchange chip
Multicast message copy on the second exchange chip of second switch and the 3rd exchange chip of 3rd switch on, meanwhile,
In first switch, multicast message is copied to first port convergence group neutralization second port convergence group on the first exchange chip
In, in second switch, multicast message is copied to first port convergence group on the second exchange chip and second port is converged
In poly- group, while being copied in the 2-port-2 of port, in 3rd switch, multicast message is answered on the 3rd exchange chip
In making first port convergence group and second port convergence group, wherein, the multicast message for copying to port 2-port-2 is normal
Forward, copy to the multicast message in first port convergence group and second port convergence group and further do forwarding inspection.
Step 3, configures the trunking group in multicast group, and each trunking group in different friendships on each switch
The member port configuration sequence changed in chip is consistent, and configures the selection strategy of each trunking group membership port, and often
The member port that trunking group selection in individual switch goes out is consistent；
Step 4, judges that whether the trunking group membership port that chooses is the port on the switch, if so, then
Multicast message is sent, otherwise, multicast message is abandoned.
Specifically, multiple trunking groups are there may be in multicast group, the member for configuring each trunking group is needed
Port order is consistent, and first port convergence group is configured in the first switch, makes member port configuration sequence consistent, this reality
In applying example, it is preferable that the member port order of first port convergence group is followed successively by 1-port-2,1-port-3,2-port-1, when

Port-1,3-port-2, configure the member port order of second port convergence group in second switch, keep with the first switch
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 order, is consistent with the first switch, is followed successively by 2-port-3,3-port-1,3-port-2.
In each trunking group, the strategy of member port is selected using identical, it is ensured that identical message is handed at each
The member port selected in the trunking group changed planes is same, and such as one multicast message enters the of the first switch
In one exchange chip, multicast message is copied to the second exchange chip and is neutralized in the 3rd exchange chip by the first exchange chip, while
Into first port convergence group and second port convergence group, multicast message is copied to duplicated multicast message 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, enters
One step judges that whether the port selected is the port on this switch, if the port on this switch, then by multicast message
Forward from the port, otherwise, multicast message is abandoned, because 1-port-2 is the port on the first switch, because
This multicast message is forwarded away from the 1-port-2 ports of the first exchange chip, and is copied to 1- in the second exchange chip
The message of port-2 ports can be dropped.
By said method, enable to multicast message and only have a message in a port convergence group to be replicated out
Go.
As shown in figure 3, the exchange chip that a kind of multicast message in distributed aggregated link network is processed, including message is multiple

In each trunking group, using the algorithm of identical selection port, it is ensured that converge the port in each switch
The port selected in poly- group is consistent, and such as one multicast message is entered in the first exchange chip of the first switch, and first hands over
Change chip and multicast message is copied to into the 3rd exchange of neutralization of the second exchange chip by the message replication module in the first switch
In chip, while duplicated multicast message is into first port convergence group neutralization second port convergence group, the second exchange chip is by group
Report text to copy 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 the 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 the 3rd exchange chip, selects
The port for going out is similarly 1-port-2, the message processing module (MPM) in first switch, second switch and 3rd switch
Determine whether that whether the port selected is the port on this switch respectively, if the port on this switch, then by group
Report text to forward from the port, otherwise, multicast message is abandoned, because 1-port-2 is the end on the first switch
Mouthful, therefore multicast message is forwarded away from the 1-port-2 ports of the first exchange chip, and copy to the second exchange chip and
The message of 1-port-2 ports can be dropped in 3rd exchange chip.
Realize in the exchange chip of switch, the physical storage device of multicast segregation table is eliminated completely, reduce friendship
The design cost of chip is changed, in addition, when trunking group adds removing members, without the need for safeguarding the relation with multicast again,
Greatly reduce the implementation complexity and maintenance cost of software；Meanwhile, the configuration of trunking group can be shared with unicast, that is, do
The message of unicast forwarding also multiplexing port convergence group configuration and select member port strategy, which ensures that unicast and multicast
For the member port that identical message is selected is identical, trunking group selection member port and forwarding side are also just accomplished
Formula is unrelated.
The technology contents and technical characteristic of the present invention have revealed that as above, but those of ordinary skill in the art still may base
Make a variety of replacements and modification without departing substantially from spirit of the present invention in teachings of the present invention and announcement, such as the switch in invention
