Detailed Description
Various exemplary embodiments, features and aspects of the present disclosure will be described in detail below with reference to the accompanying drawings. In the drawings, like reference numbers can indicate functionally identical or similar elements. While the various aspects of the embodiments are presented in drawings, the drawings are not necessarily drawn to scale unless specifically indicated.
The word "exemplary" is used exclusively herein to mean "serving as an example, embodiment, or illustration. Any embodiment described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments.
Furthermore, in the following detailed description, numerous specific details are set forth in order to provide a better understanding of the present disclosure. It will be understood by those skilled in the art that the present disclosure may be practiced without some of these specific details. In some instances, methods, means, elements and circuits that are well known to those skilled in the art have not been described in detail so as not to obscure the present disclosure.
At present, the two-layer protocol message cannot be transparently transmitted in the MPLS L2VPN network. That is, a two-layer protocol packet cannot span PE (Provider Edge) devices in an MPLS L2VPN network and is transmitted from one CE device to another CE device, so that aggregation between CE (Customer Edge) devices cannot be achieved. In the related art, in the MPLS L2VPN network, when the PE1 receives the two-layer protocol packet from the CE1, the PE1 directly transmits the received two-layer protocol packet to a local CPU (Central Processing Unit, CPU) for operation. The operation of the two-layer protocol message of the user network and the operator network will affect each other, and the user network can not independently complete the operation of the two-layer protocol message.
Fig. 1 shows a flow chart of a message sending method according to an embodiment of the present disclosure. The method is used for a first PE device, and a first interface of the first PE device is bound with a first virtual switching instance. As shown in fig. 1, the method may include steps S11 to S13.
In step S11, the first interface of the first PE device is enabled to transparently transmit the function of the layer two protocol packet.
In step S12, a first packet from a first CE device is received through a first interface of a first PE device, where the first packet is a layer two protocol packet.
In step S13, a VXLAN packet encapsulating the first packet is sent to the second PE device, so that the first packet is sent to the second CE device through the second interface of the second PE device, and the second interface of the second PE device binds the first virtual switch instance.
The function of enabling transparent transmission of the two-layer protocol message may refer to setting a physical interface of the PE device, so that the physical interface of the PE device does not transmit the two-layer protocol message to a local CPU for operation but transmits the two-layer protocol message when receiving the two-layer protocol message.
Those skilled in the art will appreciate that step S11 is a configuration step. In other words, after the function of enabling the first interface of the first PE device to transparently transmit the two-layer protocol packet is completed, the first interface of the first PE device has the function of transparently transmitting the two-layer protocol packet. In the actual application process, the first interface of the first PE device may be configured as described in step S11 in the configuration stage.
In an implementation manner, the two-layer Protocol packet may be an STP (Spanning Tree Protocol) packet, a DLDP (Device Link Detection Protocol) packet, a UDLD (Unidirectional Link Detection Protocol) packet, a PAGP (Port Aggregation Protocol) packet, or a LACP (Link Aggregation Control Protocol) packet, and the disclosure is not limited thereto.
In one implementation, sending a VXLAN packet encapsulating the first packet to the second PE device (step S13) includes: carrying out VXLAN packaging on the first message to obtain a VXLAN message for packaging the first message; and sending the VXLAN message for encapsulating the first message to the second PE equipment.

As shown in fig. 2, PE1 is connected to CE1, and PE2 is connected to CE 2. Interface 1 of PE1 binds VSI1 and interface 2 of PE2 binds VSI 1. After interface 1 of PE1 binds VSI1, interface 1 of PE1 creates AC (access Circuit) interface 1. After interface 2 of PE2 binds VSI1, interface 2 of PE2 creates AC interface 3. Since interface 1 of PE1 and interface 2 of PE2 both bind VSI1, VXLAN tunnel 1 may be established between PE1 and PE2 according to AC interface 1 and AC interface 3. Wherein, the interface 1 and the interface 2 are both physical interfaces. AC interface 1 and AC interface 3 are logical interfaces.
In one implementation, interface 1 of PE1 is enabled with the function of transparently transmitting layer two protocol packets during the configuration phase, so interface 1 of PE1 has the function of transparently transmitting layer two protocol packets. As shown in fig. 2, CE1 sends message 1 to PE1, where message 1 is a two-layer protocol message. Interface 1 of PE1 receives message 1 from CE 1. Since the interface 1 of the PE1 has the function of transparently transmitting the two-layer protocol packet, the PE1 does not transmit the packet 1 to the local CPU for operation, but sends the packet 1. The PE1 performs VXLAN encapsulation on the message 1 to obtain VXLAN message 1. PE1 sends VXLAN message 1 to PE2 through VXLAN tunnel 1.
Fig. 3 shows an exemplary flowchart of a message sending method according to an embodiment of the disclosure. The method is used for a first PE device, a first interface of the first PE device is bound with a first virtual switching instance, and the first interface of the first device is also bound with a second virtual switching instance.

In step S12, a first packet from a first CE device is received through a first interface of a first PE device, where the first packet is a layer two protocol packet.
In step S13, a VXLAN packet encapsulating the first packet is sent to the second PE device, so that the first packet is sent to the second CE device through the second interface of the second PE device, and the second interface of the second PE device binds the first virtual switch instance.
In step S14, a VXLAN packet encapsulating the first packet is sent to the third PE device, so that the first packet is sent to the third CE device through the third interface of the third PE device, and the third interface of the third PE device binds the second virtual switch instance.
Fig. 4 shows a networking schematic diagram of an application packet sending method according to an embodiment of the present disclosure. As shown in fig. 4, PE1 is connected to CE1, PE2 is connected to CE2, and PE3 is connected to CE 3. Interface 1 of PE1 binds VSI1 and VSI2, interface 2 of PE2 binds VSI1, and interface 3 of PE3 binds VSI 2. After interface 1 of PE1 binds VSI1, interface 1 of PE1 creates AC interface 1. After interface 1 of PE1 binds VSI2, interface 1 of PE1 creates AC interface 2. After interface 2 of PE2 binds VSI1, interface 2 of PE2 creates AC interface 3. After interface 3 of PE3 binds VSI2, interface 3 of PE3 creates AC interface 4. Since interface 1 of PE1 and interface 2 of PE2 both bind VSI1, VXLAN tunnel 1 may be established between PE1 and PE2 according to AC interface 1 and AC interface 3. Since interface 1 of PE1 and interface 3 of PE3 both bind VSI2, VXLAN tunnel 2 may be established between PE1 and PE3 according to AC interface 2 and AC interface 4. The interface 1, the interface 2 and the interface 3 are all physical interfaces. The AC interface 1, the AC interface 2, the AC interface 3, and the AC interface 4 are logical interfaces.
In one implementation, interface 1 of PE1 is enabled with the function of transparently transmitting layer two protocol packets during the configuration phase, so interface 1 of PE1 has the function of transparently transmitting layer two protocol packets. As shown in fig. 4, CE1 sends message 1 to PE1, where message 1 is a two-layer protocol message. Interface 1 of PE1 receives message 1 from CE 1. Since the interface 1 of the PE1 has the function of transparently transmitting the two-layer protocol packet, the PE1 does not transmit the packet 1 to the local CPU for operation, but sends the packet 1. The PE1 performs VXLAN encapsulation on the message 1 to obtain VXLAN message 1. PE1 sends VXLAN message 1 to PE2 through VXLAN tunnel 1. PE1 sends VXLAN message 1 to PE3 through VXLAN tunnel 2.
According to the message sending method, the two-layer protocol message can span PE equipment in an MPLS L2VPN network and is transmitted from one CE equipment to another CE equipment, and aggregation among the CE equipment is achieved. In addition, point-to-point transmission of two-layer protocol messages is carried out through VXLAN tunnels established among the PE devices, and tunnel resources can be effectively saved.

The method is used for a second PE device, and a second interface of the second PE device binds a first virtual switching instance. As shown in fig. 5, the method may include steps S51 to S53.
In step S51, a VXLAN packet encapsulating a first packet is received from a first PE device, and a first interface of the first PE device binds to a first virtual switch instance.
In step S52, the VXLAN packet encapsulating the first packet is decapsulated to obtain the first packet.
