 The embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

For ease of understanding, the following describes the RBs in the TRILL network: In the TRILL network, the device running the TRILL protocol is called RB. The RB has a switching function and a routing function, can recognize the topology of the TRILL network, and can generate a routing forwarding table to other RBs. At the entrance of the TRILL network, it is responsible for encapsulating the received unicast data frame into a TRILL format (ie, adding a TRILL header and an inner MAC frame header in front of the original data frame, and the encapsulated data frame is called a TRILL data frame). The RB that is forwarded to the TRILL network is called the Ingress RB. On the exit of the TRILL network, the RB that is responsible for decapsulating the TRILL data frame into the original data frame and forwarding it is called the Egress RB. Other than the Ingress RB and the Egress RB, other RBs. It is responsible for transmitting the TRILL data frame from the Ingress RB to the Egress RB, which is called the transmission RB. FIG. 1a is a flowchart of a medium access control address learning control method according to an embodiment of the present invention. Referring to FIG. 1a, the method includes:

 101. The routing bridge receives the TRILL data frame.

 The RB RB receives two data frames, one is a normal data frame and the other is a TRILL data frame. The embodiment of the present invention only focuses on the case where a TRILL data frame is received.

 102. Determine, according to the node type of the routing bridge and the TRILL data frame, whether to perform media access control address learning.

 Preferably, the RBridge receiving the TRILL data frame is configured as a preset node type according to its location in the TRILL network, and the preset node type may be a first node type (user access side node) or a second node type. (Gateway side node;), specifically configuring the type of the routing bridge, according to the location of the routing bridge in the network or according to the network transmission needs.

 According to the comparison between the node type and the TRILL data frame, it is determined whether the medium access control address learning is performed or not, so that the RB bridge determines whether to perform the medium access control address learning according to the information such as the source routing bridge of the TRILL data frame, so that the node of the RB bridge When the type and the TRILL data frame are in compliance with the condition that the medium access control address learning is not performed, the medium access control address learning is not performed, and the media access is performed when the node type of the RBridge and the data frame conform to the condition for performing the medium access control address learning. Controlling address learning, through the configuration of the node type of the routing bridge itself, achieves the purpose of control.

 Media access control address MAC address learning means that when a port of an RB receives a data frame, it analyzes the source MAC address and the virtual local area network identifier of the data frame. If the source MAC address is legal, the source MAC address and the virtual local area network identifier are used as the key value. The MAC address table is searched. If the source MAC address does not exist in the MAC address table, the source MAC address is added to the MAC address table. If the source MAC address already exists in the MAC address table, the entry is updated.

The media access control address learning control method provided by the embodiment of the present invention receives a TRILL data frame through a RBridge; and determines whether to perform media access control address learning according to the node type of the RBridge and the TRILL data frame. The technical solution provided by the embodiment of the present invention does not need to perform media access control address learning on the routing bridge in the network, and is configured to compare only the node type of the routing bridge and the received TRILL data frame, thereby controlling routing.

Optionally, based on the technical solution of the embodiment shown in FIG. 1a, the step 102: determining, according to the node type of the RBridge and the data frame, determining whether to perform media access control address learning, specifically including the following step:

The TRILL data frame includes a TRILL packet header, the packet header carries the destination RB of the TRILL data frame, and the source RB bridge. When the current RB receives the TRILL data frame, the destination RB of the data frame is obtained from the TRILL packet header. And the source RBridge.

 (2) When the TRILL data frame is a multicast data frame that is copied to the local port after the TRILL encapsulation needs to be released, or the TRILL data frame is a unicast data frame, and the destination RB of the TRILL data frame is the route. a bridge, acquiring a node type of the source routing bridge;

 In this embodiment, the node type of the source RBridge is obtained according to the mapping relationship between the locally learned RBridge and its node type. It should be noted that the mapping relationship between the RB and its node type is learned by the ISIS protocol when the RB bridge is in the network. The node type corresponding to each RB is set by the technical personnel during networking. limited.

 For a multicast data frame, when the user VLAN of the data frame has a local port on the RB, the multicast data frame is a multicast data frame that needs to be copied to the local port after the TRILL encapsulation is cancelled, and when the RB bridge receives the When the data frame is multicast, the multicast data frame needs to be copied, and the multicast data frame is sent to multiple destination RBridges according to the TRILL routing forwarding table, so that the multicast data frame can be received by multiple destination RBridges. . The determination of the multicast data frame to be copied to the local port after the TRILL encapsulation is required is disclosed in the prior art, and is not described herein.

 When the Nickname of the destination RB that is carried in the TRILL packet header of the TRILL data frame is the same as the Nickname of the RBridge, the destination RB of the TRILL data frame is the RB, and the destination RB is the RBridge. For a unicast data frame, the RB is the endpoint of the unicast data frame. The RB is the egress of the TRILL network and is responsible for decapsulating the TRILL data frame into the original data frame and forwarding it.

(3) determining, according to the node type of the RBridge and the node type of the source RBridge Or do not media access control address learning.

 Controlling whether the MAC address is learned or not is performed on the TRILL data frame according to the node type that is known by the RB and the node type of the source RB that is obtained by the mapping.

 The node type of the RB and the node type of the source RB may be the same or different. For the specific case of the node type, there may be any of the following cases: (1) When the RBridge When the node type of the node is the same as the node type of the source RBridge, it is determined that the medium access control address learning is not performed; (2) when the node type of the RBridge and the node type of the source RBridge are the same, the medium is determined to be performed.

The access node on the side is represented by a Spoken RB, and the second type may be a gateway node, that is, an access node on the LAN gateway side, represented by a Hub RB, when the node type of the RBridge and the source route If the node type of the bridge is Spoken RB, it is determined that the medium access control address learning is not performed; otherwise, the medium access control address learning is determined. Preferably, the first type or the second type may be set by the technician according to the location of the routing bridge in the network when the network is configured, for example, for the routing bridge of the user access side, the node type may be set to The first type, that is, the Spoken RB, receives the multicast data frame that needs to be copied to the port of the RB bridge, or the data frame is a unicast data frame and the purpose of the data frame. When the routing bridge is the routing bridge, it is determined that the medium access control address learning is not performed, thereby supporting the user-oriented node. Instead of learning the MAC of the attached device that is the same as the user node, learn the MAC of the attached device that is facing the gateway node.
