Description

Technical Field

[0001] This invention relates to the field of communication technology, and in particular to a method for building a router IPv6 test environment based on Kathara. Background Technology

[0002] With the depletion of global IPv4 addresses, the availability requirements for IPv6 networks are increasing, necessitating higher testing and acceptance standards for IPv6 network equipment. However, the current IPv6 testing environment is neither perfect nor standardized, relying on third-party IPv6 server providers (such as Mikrotik's software routers) for support. But using third-party IPv6 servers for testing has the following drawbacks:

[0003] (1) There are few configuration options available, and the application scenarios of IPv6 cannot be fully tested.

[0004] (2) Due to the closed-source nature, it is not easy to determine who caused the problem when a problem occurs in the test scenario.

[0005] (3) For test scenarios where third-party services cannot be configured, testers need to manually set up an IPv6 test environment, which is quite troublesome. Summary of the Invention

[0006] The purpose of this invention is to provide a method for building a router IPv6 test environment based on Kathara, so as to solve the technical problem that it is not easy to determine the source of the problem when the test environment has problems.

[0007] This invention is achieved using the following technical solution: a method for building a router IPv6 test environment based on Kathara, comprising the following steps:

[0008] S1: Set up a test environment and use the base image to virtualize routers R1 and R2 and ordinary computers PC1 and PC2;

[0009] S2: Write the configuration files for routers R1 and R2 respectively;

[0010] S3: Write the basic configuration file and runtime script for router R2 respectively;

[0011] S4: Write the startup scripts for routers R1 and R2 and ordinary computers PC1 and PC2 respectively;

[0012] S5: Configure the startup dependencies between routers R1 and R2 and ordinary computers PC1 and PC2, and control the startup order.

[0013] Further, step S1 specifically involves: using Kathara to build a test environment, configuring Kathara's base image as kathara / quagga, and enabling IPv6 functionality.

[0014] Furthermore, the base image contains a dibbler-server, a radvd server, a pppd server, and a pppoe-server.

[0015] Furthermore, step S2 includes the following sub-steps:

[0016] S21: Write the configuration files for the pppd server and radvd server of router R1;

[0017] S22: Write the configuration file for the PPPoE-server server and the IPv6-up script for router R2.

[0018] Furthermore, step S3 includes the following sub-steps:

[0019] S31: Write the basic configuration file for the dibbler-server server of router R2;

[0020] S32: Write the script to run the dibbler-server on router R2.

[0021] Furthermore, the basic configuration file includes an address pool, expiration date, and DNS signals.

[0022] Furthermore, step S4 includes the following sub-steps:

[0023] S41: Write the startup scripts for ordinary computers PC1 and PC2, and configure the static IPv6 address for the eth0 interface;

[0024] S42: Write the startup script for router R1, and immediately use the configuration file to make PPP dialing after it starts up;

[0025] S43: Write the startup script for router R2, configure the interface addresses, and start the radvd service and pppoe-server service.

[0026] Furthermore, step S5 specifically involves: establishing the boot dependencies between routers R1 and R2 and ordinary computers PC1 and PC2 to ensure the boot order of the devices.

[0027] The advantages of this invention are as follows: The servers are manually set up, and all configuration parameters can be arbitrarily configured according to the needs of the test scenario; each virtual device is a fully functional Linux host, and the running status and logs of service processes can be easily viewed, facilitating analysis of which party is at fault when problems occur. Once the simulation environment is configured, it can be easily moved to other testers' computers, ensuring consistency of test results among different testers and improving testing efficiency; it has good scalability; when adding other network devices to the network, only the configuration of the connected devices needs to be modified.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0031] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0032] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0033] Example 1

[0034] See Figure 1 A method for setting up a router IPv6 test environment based on Kathara includes the following steps:

[0035] Step 1: Install the Kathara environment. Configure the base image for Kathara as kathara / quagga, enable IPv6, and install the dibbler-server, radvd, pppd, and pppoe-server servers within the base image. Kathara is a Docker-based network emulation tool that inherits the lightweight advantages of Docker, allowing for fast startup of virtual network devices. It's used to virtualize routers and hosts within a network environment, where each network device operates independently, and all network configurations can be modified independently.

[0036] Step two, according to Figure 1 Write the configuration file lab.conf for the Kathara virtual environment, and use the base image to virtualize routers R1 and R2, and ordinary computers PC1 and PC2.

[0037] Step 3: Write the startup scripts for ordinary computers PC1 and PC2, and configure the static IPv6 address for the eth0 interface.

[0038] Step 4: Write the configuration file for the pppd server of router R1, configure the dial-up password, information to be obtained after dialing, etc.; configure the configuration file for the radvd server and assign addresses to the downstream hosts.

[0039] Step 5: Write the startup script for router R1. Once it starts up, immediately use the configuration file to make PPP dialing.

[0040] Step 6: Write the configuration file for the PPPoE-server on router R2, as well as the IPv6-up script. The key components of the IPv6-up script are dynamically generating the configuration file for the dibbler-server and starting the dibbler-server service on the corresponding PPP interface.

[0041] Step 7: Write the basic configuration file for the dibbler-server of router R2, configuring information such as address pool, validity period, and DNS.

[0042] Step 8: Write the script to run the dibbler-server on router R2, record the prefix when allocating the IPv6 proxy prefix, and add static routes based on this prefix.

[0043] Step 9: Write the startup script for router R2, configure the interface addresses, and start the radvd service and pppoe-server service.

[0044] Step 10: Write the boot dependencies for PC1 and PC2 and routers R1 and R2 to ensure the boot order of the devices.

[0045] Step 11: Bind network B to the physical interface of the physical machine so that the device under test can connect.

[0046] The above are the steps for setting up an IPv6 testing environment. The usage of this environment is as follows:

[0047] 1. Connect the WAN port of the device under test to the physical interface bound in step eleven above.

[0048] 2. Use the `kathara lstart` command to start the test environment and begin testing.

[0049] Based on the above embodiments, the present invention has at least the following technical effects: In this invention, the servers are all manually set up, and all configuration parameters can be arbitrarily configured according to the needs of the test scenario; each virtual device is a fully functional Linux host, and the running status and logs of the service processes can be easily viewed, facilitating analysis of which party is at fault when problems occur. After the simulation environment is configured, it can be easily moved to other testers' computers, ensuring consistency of test results among different testers and improving testing efficiency; it has good scalability; when adding other network devices to the network, only the configuration of the connected devices needs to be modified.
