[0002] User terminals in a LAN usually access external networks by configuring a default gateway. If the default gateway device fails, all user traffic to the external network will be terminated.

[0048] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0049] The message forwarding method provided in the embodiment of the present application can be applied to Figure 1In the application environment shown. Among them, the gateway device 101 in the VRRP group is the main gateway device, which is the gateway device that actually forwards data packets in the VRRP group; the gateway device 102 is the backup gateway device; the user terminal 1, the user terminal 2 and the user terminal 3 are all user terminals that communicate with the Internet (i.e., the network end); the first switch 103 and the second switch 104 are switches that realize communication between the user end and the network end, wherein the first switch 103 is a switch between the network end and the gateway device, and the second switch 104 is a switch between the gateway device and the user terminal. If the target data message received by the gateway device is forwarded by the first switch, the first switch is the source switch and the second switch is the target switch; correspondingly, if the target data message received by the gateway device is forwarded by the second switch, the second switch is the source switch and the first switch is the target switch.

[0050] Optionally, after the gateway identity of the gateway device 101 is switched from the primary gateway to the backup gateway, the virtual media access control address MAC and the virtual network address IP configured when the gateway identity of the gateway device 101 is the primary gateway are retained; after receiving the target data packet sent by the source switch, the target data packet is forwarded to the target switch 103 according to the message transmission information, virtual MAC and virtual IP of the target data packet; wherein the message transmission information includes the destination MAC and destination IP of the target data packet.

[0051] In one embodiment, Figure 2 As shown, a message forwarding method is provided, which is applied to Figure 1 The following steps are taken as an example to illustrate the gateway device in the VRRP group:

[0052] S201, after the gateway identity of the gateway device is switched from the active gateway to the standby gateway, retain the virtual media access control address MAC and the virtual network address IP configured when the gateway identity of the gateway device is the active gateway.

[0053] The gateway device is a gateway device in a VRRP group, that is, a router in a VRRP group; when the gateway identity of the gateway device is a master gateway, the gateway device is a master gateway (MASTER) device; correspondingly, when the gateway identity of the gateway device is a backup gateway, the gateway device is a backup gateway (BACKUP) device.

[0054] It should be noted that in a VRRP group, there are multiple VRRP routers (gateway devices), which are identified by the same VRID (Virtual Router Identity Document). The virtual media access control address (MAC) is the MAC address generated by the virtual router in the VRRP group according to the VRID. A virtual router has a virtual MAC address. The virtual network address (IP) is the IP address of the virtual router. The virtual IP is actually the user's gateway address.

[0055] Optionally, when the gateway device whose gateway identity is the primary gateway in the VRRP group (i.e., the primary gateway device) fails or needs to be upgraded, the gateway identity needs to be switched to the backup gateway first. At the same time, the virtual MAC and virtual IP configured when the gateway identity of the gateway device is the primary gateway are still retained.

[0056] S202: After receiving the target data message sent by the source switch, forward the target data message to the target switch according to the message transmission information, virtual MAC and virtual IP of the target data message.

[0057] The message transmission information includes the destination MAC and destination IP of the target data message.

[0058] Optionally, after receiving the target data message sent by the source switch, the message transmission information of the target data message, that is, the destination MAC and destination IP of the target data message, is extracted; further, the destination MAC of the target data message can be verified. If the destination MAC of the target data message is a virtual MAC, the target data message is allowed to enter the processing flow of the local machine. In addition, according to the switch type of the source switch, it can be determined whether the destination IP needs to be further authenticated. If verification is not required, the target data message can be directly forwarded to the target switch; if verification is required, the target data message is forwarded to the target switch after the authentication is passed.

[0059] It should be noted that after the active gateway device is switched to the standby gateway device, VRRP will switch the new active gateway device through election. At this time, the virtual MAC and virtual IP will be configured on the new active gateway device. The new active gateway device can process messages normally, and will also use the virtual MAC to respond to the user device's ARP (Address Resolution Protocol) request for the virtual IP and regularly notify GARP (Gratuitous Address Resolution Protocol, free ARP). However, the gateway device whose gateway identity is switched from the active gateway to the standby gateway will stop responding to the Address Resolution Protocol ARP request sent by the user terminal; the destination IP carried in the ARP request is the virtual IP. It can be understood that this ensures that the neighbor table entry of the user device is only updated by the new active gateway device.

[0060] In the above-mentioned message forwarding method, after the gateway identity of the gateway device is switched from the primary gateway to the backup gateway, the virtual media access control address MAC and virtual network address IP configured when the gateway identity of the gateway device is the primary gateway are retained; after receiving the target data message sent by the source switch, the target data message is forwarded to the target switch according to the message transmission information, virtual MAC and virtual IP of the target data message; wherein the message transmission information includes the destination MAC and destination IP of the target data message. The above-mentioned scheme, by retaining the configured virtual MAC and virtual IP after the primary gateway device is switched to the backup gateway device, enables the gateway device to still accept the target data message when it is the backup gateway device; further, by combining the destination MAC and destination IP of the target data message, as well as the virtual MAC and virtual IP, it is ensured that the target data message can be forwarded correctly, thereby avoiding the loss of the target data message to a certain extent.

[0061] Optionally, in one embodiment, Figure 3 As shown, a method for forwarding a target data message to a target switch is provided, which specifically includes the following steps:

[0062] S301, determining whether a target data message meets a processing condition according to a destination MAC, a virtual MAC and an actual MAC of a gateway device.

[0063] The destination MAC is the MAC address of the target device to which the target data message carried in the target data message is to go.

[0064] Optionally, if the destination MAC is consistent with any one of the virtual MAC and the actual MAC, it is determined that the target data message meets the processing condition.

[0065] S302: If it matches, forward the target data message to the target switch according to the switch type and destination IP of the source switch.

[0066] The destination IP is the IP address of the target device to which the target data message carried in the target data message is to go.

[0067] It can be understood that since the gateway device can receive both data packets initiated by the network end and data packets sent by the user terminal, when processing the data packets sent from the network end, there is no need to verify the destination IP carried in the target data packet. Therefore, if the source switch is determined to be the first switch based on the switch type of the source switch, the target data packet is forwarded to the target switch; wherein the first switch is a switch between the network end and the gateway device.

[0068] Correspondingly, if the source switch is determined to be the second switch according to the switch type of the source switch, the destination IP and the virtual IP are compared for consistency to obtain an IP comparison result, and if the IP comparison result is consistent, the target data message is forwarded to the target switch; wherein the second switch is the switch between the gateway device and the user terminal. Specifically, if the IP comparison result is consistent, it is necessary to perform a route search according to the routing table item issued by the configuration, and further, after obtaining the next hop related information of the target data message, the target data message is forwarded to the target switch.

[0069] In this embodiment, by preliminarily verifying whether the target data message meets the message processing conditions based on the destination MAC, virtual MAC, and actual MAC, and further determining different target data message forwarding processes based on the switch type of the source switch, it is equivalent to introducing the judgment logic of the target data message, ensuring that the gateway device whose gateway identity is switched from the main gateway to the backup gateway can process the message with the destination MAC as the virtual MAC.

[0070] Optionally, in one embodiment, Figure 4 As shown, a method for forwarding a target data message to a target switch is provided, which specifically includes the following steps:

[0071] S401, obtaining next hop encapsulation information of a target data message.

[0072] The next hop encapsulation information at least includes the sending interface information, the virtual local area network VLAN information and the next hop MAC.

[0073] Optionally, the next hop related information of the target data message may be searched through relevant commands, and encapsulation information used for MAC encapsulation may be extracted according to the next hop related information as the next hop encapsulation information of the target data message.

[0074] S402: Perform MAC encapsulation on the target data message according to the next hop encapsulation information and the actual MAC.

[0075] Optionally, the target data message may be automatically MAC encapsulated according to the MAC encapsulation process and the next hop encapsulation information and the actual MAC.

[0076] S403: Forward the target data message after MAC encapsulation to the target switch.

[0077] In this embodiment, by introducing the next hop encapsulation information and the actual MAC to perform MAC encapsulation on the target data message, an optional process of MAC encapsulation is provided, thereby ensuring the accuracy of MAC encapsulation on the target data message.

[0078] Optionally, in one embodiment, Figure 5 As shown, a method for performing MAC encapsulation on a target data message is provided, which specifically includes the following steps:

[0079] S501, using the actual MAC as the new source MAC of the target data message.

[0080] The new source MAC is the source MAC of the target data message when the gateway device forwards the target data message.

[0081] Optionally, in order to prevent the forwarding traffic of the gateway device that switches from the primary gateway to the backup gateway from pulling the traffic of the new primary gateway device, the actual MAC can be used as the new source MAC of the target data message. Correspondingly, for the new primary gateway device, the virtual MAC is used as the new source MAC of the target data message.

[0082] S502: Use the next-hop MAC as the new destination MAC of the target data message.

[0083] The new destination MAC is the destination MAC of the target data message when the gateway device forwards the target data message.

[0084] Optionally, the next hop MAC is used as the new destination MAC of the target data message. It can be understood that if the target switch is the second switch, that is, the switch between the gateway device and the user terminal, the new destination MAC is the interface MAC of the user terminal.

[0085] S503, performing MAC encapsulation on the target data message according to the new destination MAC, the new source MAC, the sending interface information and the VLAN information.

[0086] Optionally, according to the MAC encapsulation process, the target data message is automatically MAC encapsulated according to the new destination MAC, the new source MAC, the sending interface information and the VLAN information.

[0087] In this embodiment, for a gateway device whose gateway identity is switched from an active gateway to a standby gateway, the actual MAC of the target data message forwarded by the gateway device is used as the new source MAC, thereby preventing the forwarding traffic of the gateway device from drawing the traffic of the new active gateway device.

[0088] Figure 6 FIG. 2 is a flow chart of a message forwarding method in another embodiment. Based on the above embodiment, this embodiment provides an optional example of a message forwarding method. Figure 6 The specific implementation process is as follows:

[0089] S601, after the gateway identity of the gateway device is switched from the active gateway to the standby gateway, the virtual MAC and virtual IP configured when the gateway identity of the gateway device is the active gateway are retained.

[0090] S602: After receiving the target data message sent by the source switch, obtain the destination MAC and destination IP of the target data message.

[0091] S603, determine whether the destination MAC is the actual MAC of the gateway device; if so, execute S605; if not, execute S604.

[0092] S604, determine whether the destination MAC is a virtual MAC; if so, execute S605; if not, prohibit processing of the target data message.

[0093] S605, determining whether the source switch is the first switch; if so, executing S607; if not, executing S606.

[0094] S606, compare the destination IP and the virtual IP for consistency to obtain an IP comparison result; if the IP comparison result is consistent, execute S607.

[0095] S607: Obtain next hop encapsulation information of the target data message.

[0096] S608: Use the next hop MAC in the next hop encapsulation information as the new destination MAC of the target data message.

[0097] S609: Use the actual MAC as the new source MAC of the target data message.

[0098] S610, perform MAC encapsulation on the target data message according to the new destination MAC, the new source MAC, the outgoing interface information and the VLAN information in the next hop encapsulation information.

[0099] S611, forwarding the target data message after MAC encapsulation to the target switch.

[0100] The specific process of S601-S611 can refer to the description of the above method embodiment, and its implementation principle and technical effect are similar, which will not be repeated here.

[0101] It should be understood that, although the various steps in the flowcharts involved in the above-mentioned embodiments are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows.
