Yuav tsum paub

Txhawm rau kom tsab xov xwm tsis hloov mus rau hauv ib daim ntawv, kuv tshem tawm qee qhov kev qhia (nrog rau cov ntawv txuas mus rau cov ntaub ntawv uas koj tuaj yeem nyeem txog lawv).

Hauv qhov kev sib txuas no, kuv muab cov ntsiab lus rau koj tias nws yuav zoo (tab sis yuav luag tsis tsim nyog) kom paub ua ntej nyeem:

Ntu 1: qee qhov kev xav

Ib qho qhib SDN platform rau kev tswj thiab automating txhua yam kev tes hauj lwm, txhawb los ntawm Linux Foundation
Java sab hauv
Raws li Model-Driven Service Abstraction Level (MD-SAL)
Siv YANG qauv kom tau txais kev tsim RESTCONF APIs rau cov khoom siv hauv network

Lub ntsiab module rau kev tswj network. Nws yog los ntawm nws uas peb yuav sib txuas lus nrog cov khoom siv sib txuas. Tswj los ntawm nws tus kheej API.

Koj tuaj yeem nyeem ntxiv txog OpenDaylight no.

API test tool
Yooj yim thiab yooj yim siv interface

Hauv peb cov ntaub ntawv, peb txaus siab rau nws los ua ib txoj hauv kev xa REST thov rau OpenDaylight API. Koj tuaj yeem, tau kawg, xa cov ntawv thov manually, tab sis hauv Postman txhua yam zoo li meej heev thiab haum rau peb lub hom phiaj zoo kawg nkaus.

Rau cov neeg uas xav khawb: ntau cov ntaub ntawv kawm tau sau rau ntawm nws (piv txwv).

Cov cuab yeej siv rau kev xa tawm virtual routers hauv Docker
Txhawb nqa: Cisco XRv, Juniper vMX, Arista vEOS, Nokia VSR, thiab lwm yam.
qhib Tau qhov twg los

Ib tug heev nthuav tab sis tsis paub instrument. Hauv peb cov ntaub ntawv, peb yuav siv nws los khiav Juniper vMX thiab Cisco xRV9000 ntawm ib txwm Ubuntu 20.04 LTS.

Koj tuaj yeem nyeem ntxiv txog nws ntawm nplooj ntawv qhov project.

Part 2: Lab

Hauv qhov kev qhia no, peb yuav teeb tsa cov kab ke hauv qab no:

Yuav ua li cas li no ua hauj lwm

Juniper vMX nce hauv docker thawv (los ntawm txhais tau tias Vrnetlab) thiab ua haujlwm raws li qhov feem ntau virtual router.
ODL txuas nrog lub router thiab tso cai rau koj los tswj nws.
Tus xaib launched ntawm ib lub tshuab cais thiab los ntawm nws peb xa cov lus txib ODL: txhawm rau txuas / tshem tawm lub router, hloov qhov kev teeb tsa, thiab lwm yam.

Cov lus piav qhia ntawm lub cuab yeej ntawm qhov system

Juniper vMX и ODL xav tau ntau cov peev txheej rau lawv txoj haujlwm ruaj khov. Ib leeg xwb vMX nug txog 6 Gb ntawm RAM thiab 4 cores. Yog li ntawd, nws tau txiav txim siab txav tag nrho cov "heavyweights" mus rau ib lub tshuab cais (Heulett Packard Enterprise MicroServer ProLiant Gen8, Ubuntu 20.04 LTS). Lub router, ntawm chav kawm, tsis "ya" rau nws, tab sis qhov kev ua tau zoo txaus rau kev sim me me.

Ntu 3: Teeb OpenDaylight

Tam sim no version ntawm ODL thaum lub sijhawm sau ntawv no yog Magnesium SR1

1) Nruab Java Qhib JDK 11 (rau kev txhim kho kom ntxaws ntxiv no)

ubuntu:~$ sudo apt install default-jdk

2) Nrhiav thiab rub tawm qhov tsim tshiab ODL ntawm no
3) Unzip lub downloaded archive
4) Mus rau qhov tshwm sim directory
5) Tua tawm ./bin/karaf

Hauv kauj ruam no ODL yuav tsum pib thiab peb yuav pom peb tus kheej hauv lub console (Chaw nres nkoj 8181 yog siv rau kev nkag los ntawm sab nraud, uas peb yuav siv tom qab).

Tom ntej no, nruab ODL ntatsim los ua haujlwm nrog cov txheej txheem NETCONF и RESTCONF. Txhawm rau ua qhov no hauv console ODL peb execute:

opendaylight-user@root> feature:install odl-netconf-topology odl-restconf-all

Qhov no yog qhov kev teeb tsa yooj yim tshaj plaws. ODL ua tiav. (Yog xav paub ntxiv, saib no).

Part 4: Teeb tsa Vrnetlab

Kev npaj qhov system

Ua ntej kev teeb tsa Vrnetlab koj yuav tsum tau nruab cov pob khoom xav tau rau nws txoj haujlwm. Xws li docker, git, sshpass:

ubuntu:~$ sudo apt update
ubuntu:~$ sudo apt -y install python3-bs4 sshpass make
ubuntu:~$ sudo apt -y install git
ubuntu:~$ sudo apt install -y 
    apt-transport-https ca-certificates 
    curl gnupg-agent software-properties-common
ubuntu:~$ curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
ubuntu:~$ sudo add-apt-repository 
   "deb [arch=amd64] https://download.docker.com/linux/ubuntu 
   $(lsb_release -cs) 
   stable"
ubuntu:~$ sudo apt update
ubuntu:~$ sudo apt install -y docker-ce docker-ce-cli containerd.io

Txhim kho Vrnetlab

Rau kev teeb tsa Vrnetlab clone cov ntaub ntawv sib raug zoo los ntawm github:

ubuntu:~$ cd ~
ubuntu:~$ git clone https://github.com/plajjan/vrnetlab.git

Mus rau phau ntawv qhia vrnetlab:

ubuntu:~$ cd ~/vrnetlab

Ntawm no koj tuaj yeem pom tag nrho cov ntawv sau uas xav tau los khiav. Thov nco ntsoov tias cov ntaub ntawv sib txuas tau tsim rau txhua hom router:
