Shulou(Shulou.com)06/01 Report--

With regard to this experiment, first of all, I would like to thank the technical god for teaching me to learn BGP, ISIS, MPLS, SR and other protocols, as well as ODL and Pathman-SR to control the network. I spent two days learning BGP and MPSL for this experiment.

And spent hours studying ISIS. The later installation of ODL and SR took × × weeks. Whether ODL or Pathman-SR, it was a pit, and I almost gave up, but thanks to the technical advice, it was successfully completed.

ODL (OpenDayLight) is a modular, scalable, scalable, multi-protocol controller framework developed based on SDN. In fact, you can refer to the official website. The following is a diagram of the ODL controller architecture:

1. The system needs to be installed for the following:

1.1 Linux CentOS (6.8) + JDK (1.7 +), personal habits CentOS + Python (2.7.3)

1.2 ODL (Nitrogen SR1 0.7.1). The installation of ODL is relatively simple. Please refer to the official website. But there is a trap. As a novice, I install all the plug-ins.

1.3 Pathman-SR needs the support of JDK 1.7, and the installation is relatively simple. Install the official website installation documentation step by step, and then you only need to modify the IP.

1.4 EVE-NG, this is an artifact, you can experiment with anything, welfare! You need to import the IOS of XR and XE routers that support SR protocol.

The following figure shows the network topology diagram of this lab:

Pmur01 runs BGP, ISIS, Segment Routing and runs BGP, ISIS, Segment Routing to connect PE-01 and PE-02 for RR and ODL ControllerL

Pmur02-- Pmur06 runs ISIS and Segment Routing

II. ODL Controller description

2.1It is easy to install ODL. Download it from the official website and decompress it to the specified directory. You need to change the org.apache.karaf.management.cfg file parameters before installation, as follows:

2.2 after the modification is completed, go to the / opt/karaf/bin directory and run the. / kararf command, as shown below:

2.3 if you use feature:install to install various pieces, for a novice like me, I install all the plug-ins. About how to use the feature command, please refer to the official website.

2.4 modify the file / opt/karaf/etc/opendaylight/bgp/protocols-config.xml of BGP, as shown below:

2.5. Because ODL needs to connect to the router and establish BGP neighbors, to change the default port of the original ODL BGP from 1790 to 179, you can use postman to modify it, as shown below:

2.6 restart ODL and use netstat-antp after completing the above jobs | whether grep 179 is working properly:

V. Pathman-SR configuration

5.1After completing the above router configuration, enter the pathman-sr installation directory and use. / odl_test.py to check whether the configuration is correct. There are three check items, bgp netconf pcep, as shown below.

5.2 if there is no problem with the check, execute. / rest_server_v6.py, and then open http://172.16.100.201:8020/cisco-ctao/apps/pathman_sr/index.html on the browser to see the topology diagram, as shown below:

5.3Test ODL control routes, such as pe01-- > pe-02

5.4 choose one of the routes and execute them, as shown in the figure:
