Embodiment 1

[0029] According to an embodiment of the present invention, a method for establishing a static MPLS tunnel forwarding table is provided, which simplifies the configuration data items of a static MPLS tunnel, only needs to specify the physical exit of the tunnel, and uses the default VLAN and MAC information to set up a static MPLS tunnel forwarding table, reducing It reduces configuration complexity and configuration errors caused by human factors, and improves the configuration efficiency of static MPLS tunnels.

[0030] figure 1It is a flowchart of a method for establishing a static MPLS tunnel forwarding table according to an embodiment of the present invention, such as figure 1 As shown, the method includes the following steps (step S102-step S108):

[0031] Step S102, acquiring configuration information of the static MPLS tunnel of the network element, where only the label of the static MPLS tunnel and the physical egress port of the static MPLS tunnel are specified in t...

Embodiment 2

[0043] According to an embodiment of the present invention, a method for transmitting static MPLS tunnel data is provided, which can realize the transmission of static MPLS tunnel data in the static MPLS tunnel established by the method and device of the above embodiments of the present invention.

[0044] image 3 is a flow chart of a static MPLS tunnel data transmission method according to an embodiment of the present invention, such as image 3 As shown, the method includes the following steps (step S302-step S304):

[0045] Step S302, when the data message needs to be sent, the sending end device encapsulates the destination MAC address of the data message as a pre-configured default MAC address and encapsulates the VLAN of the data message as a pre-configured MAC address according to the forwarding table of the static MPLS tunnel. The default VLAN.

[0046] In step S304, the sending end device sends the encapsulated data packet from the physical egress port specified by...

Embodiment 3

[0063] According to an embodiment of the present invention, a method for establishing a forwarding table of a configuration-free static MPLS tunnel is provided, such as Figure 7 As shown, the main steps are as follows:

[0064] Step S702, configure default (ie, default) MAC and default VLAN based on the network element. Configure the attribute "whether it supports configuration-free" based on the Ethernet port, which is not supported by default. If it is "not supported", keep the original way of processing. The "Support" attribute can only be used in point-to-point ETH links, without using the logical segment layer, and in non-docking situations, that is, the port of the docking device must also enable the configuration-free function. Configuration-free is applicable to the scenario where the entire network supports this attribute.

[0065] Step S704, configuring a configuration-free static MPLS tunnel on the network management system, only specifying the physical egress p...

Abstract

The invention discloses a method and device for establishing a static MPLS (Multi-Protocol Label Switch) tunnel forwarding table and transmitting data. The method for establishing the forwarding table comprises the following steps of: obtaining configuration information of a static MPLS tunnel of a network element, wherein the configuration information only appoints a label of the static MPLS tunnel and a physical outlet port of the static MPLS tunnel; judging whether the next IP (Internet Protocol) address in the configuration information is 0 or not; if so, obtaining a pre-configured defaulted MAC (Media Access Control) address and a defaulted VLAN (Virtual Local Area Network); and utilizing the defaulted MAC address and the defaulted VLAN to establish a static MPLS tunnel forwarding table. With the adoption of the method and device disclosed by the invention, the configuration complexity and the configuration errors caused by personal factors are reduced, so as to improve the configuration efficiency of the static MPLS tunnel.

Description

technical field [0001] The invention relates to the communication field, in particular to a static MPLS tunnel forwarding table establishment and data transmission method and device. Background technique [0002] At present, static tunnels are mostly used in the bearer network to complete service transmission. When a Packet Transfer Network (PTN) device configures a static Multi-Protocol Label Switching (MPLS) tunnel, it is necessary to manually configure each device that the tunnel path passes through hop by hop. Configure information such as the exit / entry port, exit / entry label, and next hop of the tunnel. The forwarding table of the tunnel retrieves the local egress and virtual local area network (Virtual Local Area Network, VLAN) encapsulation through the next-hop Internet Protocol (Internet Protocol, referred to as IP), and uses the address translation protocol corresponding to the next-hop IP (Address Resolution Protocol, abbreviated as ARP) information to obtain th...
