Process is briefly described.As shown in Figure 1, server S erver A is accessed in TRILL network by RB1, RB2 and RB3,
Server B is accessed in TRILL network by RB4.Wherein RB3 is the DRB returned on access link, RB1 where Server A more
It is the specified AVF of Server A for the DRB, i.e., specified RB1 is Server A forwarding data packets.When RB1 breaks down,
DRB is new AVF by reassigning RB2, i.e., specified RB2 is Server A forwarding data packets, this process is exactly that AVF is cut
The process changed.
It should be noted that the embodiment of the present invention does not limit access server in TRILL network, the quantity of RB and clothes
The concrete mode of business device access RB.
For ease of description, the corresponding RB of different server is subjected to area with " first ", " second " in the embodiment of the present invention
Point, different server is distinguished with " first ", " second ".Such as: in the network architecture shown in Fig. 1, it can incite somebody to action
Server A is known as first server, and Server A accesses TRILL network by RB1, RB2 and RB3, appoints in RB1, RB2 and RB3
One RB is known as the first RB, Server B is known as second server, the corresponding RB of second server is known as the 2nd RB.
It should be noted that " first ", " second " are used only for distinguishing different RB or different servers, do not limit
Sequence between RB or between server.
The embodiment of the present invention provides a kind of method of message forwarding, can be applied in TRILL network as shown in Figure 1, such as
Shown in Fig. 2, which comprises
101, the first RB receives the first message that the DRB is sent.
Wherein, for the first RB for accessing first server, first server accesses TRILL net more by the way of returning access
Network, the first RB can be any one RB for more returning the chain road of access.
First message is used to specify the first RB as specified after the corresponding switching of first server of access
Virtual LAN transponder AVF, first message include virtual LAN VLAN mark, switching after AVF mark and
The mark of designated port after switching, the designated port are identified as the first RB for accessing the first server
The mark of port.
Optionally, before this step, the first RB can send third message to DRB, and the third message learns for DRB
The VLAN of first RB is identified, the mark of the port of the mark of the first RB and the first RB for accessing first server, here
Third message can be TRILL hello packet.
As a kind of specific embodiment, the first message can be TRILL hello packet, when DRB needs to switch the first clothes
Be engaged in device corresponding AVF when, new TRILL hello packet can be sent to the RB for the chain road for more returning access, the TRILL Hello
Message includes the information of new AVF, and specifically, AVF information includes: VLAN mark, the mark of AVF, the mark of designated port.
The mark of AVF refers to the pet name (Nickname) of the AVF in TRILL hello packet for first server distribution；Designated ends
Mouthful mark refer to AVF access first server port mark, and the mark that AVF accesses the port of first server can be with
It is obtained from the TRILL hello packet that the AVF is sent to DRB.
Illustratively, TRILL network as shown in connection with fig. 1 is RB1 with the AVF before the corresponding switching of Server A, switching
For AVF afterwards is RB2, then the mark of the AVF after switching in TRILL hello packet at this time is the mark of RB2, specify
The mark of port is the mark of the port of RB2 access Server A.
102, when the mark of the first RB is identical with the mark of the AVF after the switching, the first RB is to second
RB sends the second message.
