Network automation. Ib rooj plaub ntawm ib lub neej

Hlo Habr!

Hauv tsab xov xwm no peb xav tham txog automation ntawm network infrastructure. Daim duab ua haujlwm ntawm lub network uas ua haujlwm hauv ib lub tuam txhab me tab sis txaus siab heev yuav raug nthuav tawm. Txhua qhov kev sib tw nrog cov khoom siv network tiag tiag yog random. Peb yuav saib ib rooj plaub uas tshwm sim hauv lub network no, uas tuaj yeem ua rau muaj kev lag luam kaw rau lub sijhawm ntev thiab kev poob nyiaj txiag loj. Kev daws rau qhov teeb meem no haum zoo heev rau lub tswv yim ntawm "Automation ntawm network infrastructure". Siv cov cuab yeej automation, peb yuav qhia tias koj tuaj yeem daws cov teeb meem nyuaj li cas hauv lub sijhawm luv luv, thiab peb yuav xav txog vim li cas cov teeb meem no yuav tsum tau daws los ntawm txoj kev no thiab tsis yog lwm yam (ntawm lub console).

Disclaimer

Peb cov cuab yeej tseem ceeb rau automation yog Ansible (raws li cov cuab yeej automation) thiab Git (raws li qhov chaw cia rau Ansible playbooks). Kuv xav tam sim ntawd ua qhov tshwj xeeb tias qhov no tsis yog ib tsab xov xwm qhia, uas peb tham txog cov laj thawj ntawm Ansible lossis Git, thiab piav qhia txog cov ntsiab lus tseem ceeb (piv txwv li, dab tsi yog roletaskimodules, cov ntaub ntawv cov khoom muag, cov hloov pauv hauv Ansible, lossis yuav ua li cas thaum koj nkag mus rau git thawb lossis git ua cov lus txib). Zaj dab neeg no tsis yog hais txog yuav ua li cas koj tuaj yeem xyaum Ansible thiab teeb tsa NTP lossis SMTP ntawm koj cov khoom siv. Qhov no yog ib zaj dab neeg hais txog yuav ua li cas koj tuaj yeem sai thiab zoo dua daws qhov teeb meem network yam tsis muaj qhov yuam kev. Nws kuj tseem pom zoo kom muaj kev nkag siab zoo txog kev ua haujlwm network li cas, tshwj xeeb yog dab tsi TCP / IP, OSPF, BGP raws tu qauv pawg. Peb tseem yuav muab qhov kev xaiv ntawm Ansible thiab Git tawm ntawm qhov sib npaug. Yog tias koj tseem xav tau xaiv cov kev daws teeb meem tshwj xeeb, peb xav kom nyeem phau ntawv "Network Programmability thiab Automation. Kev txawj ntse rau Next-Generation Network Engineer" los ntawm Jason Edelman, Scott S. Lowe, thiab Matt Oswalt.

Tam sim no mus rau lub ntsiab lus.

Nqe lus ntawm qhov teeb meem

Cia peb xav txog qhov xwm txheej: 3 teev sawv ntxov, koj tsaug zog thiab npau suav. Xov tooj. Tus thawj coj technical hu:

- Yog?
- ###, ####, #####, firewall pawg tau poob thiab tsis nce !!!
Koj rub koj ob lub qhov muag, sim nkag siab tias muaj dab tsi tshwm sim thiab xav txog seb qhov no tuaj yeem tshwm sim li cas. Hauv xov tooj koj tuaj yeem hnov ​​​​cov plaub hau ntawm tus thawj coj lub taub hau tearing, thiab nws thov kom hu rov qab vim tias tus thawj coj hu nws ntawm kab thib ob.

Ib nrab teev tom qab ntawd, koj tau sau thawj cov lus qhia los ntawm lub luag haujlwm ua haujlwm, tsa txhua tus neeg uas tuaj yeem sawv. Raws li qhov tshwm sim, tus thawj coj ua haujlwm tsis tau dag, txhua yam yog raws li nws yog, pawg tseem ceeb ntawm cov foob pob hluav taws tau poob, thiab tsis muaj kev txav hauv lub cev coj nws mus rau nws lub siab. Tag nrho cov kev pabcuam uas lub tuam txhab muab tsis ua haujlwm.

Xaiv qhov teeb meem rau koj saj, txhua tus yuav nco ntsoov qee yam txawv. Piv txwv li, tom qab kev hloov kho thaum hmo ntuj thaum tsis muaj lub nra hnyav, txhua yam ua haujlwm zoo, thiab txhua tus tau mus pw zoo siab. Kev khiav tsheb tau pib ntws, thiab qhov sib txuas buffers pib dhau vim muaj kab laum hauv lub network card tsav tsheb.

Jackie Chan tuaj yeem piav qhia qhov xwm txheej zoo.

Ua tsaug, Jackie.

Tsis yog qhov xwm txheej zoo siab heev, puas yog?

Cia peb cov kwv tij nrog nws txoj kev xav tu siab ib pliag.

Cia peb tham txog yuav ua li cas cov xwm txheej yuav txhim kho ntxiv mus.

Peb muab cov lus txib nram qab no ntawm kev nthuav qhia cov khoom

1. Cia peb saib ntawm daim duab kos duab thiab saib seb nws ua haujlwm li cas;
2. Peb yuav piav qhia txog yuav ua li cas peb hloov chaw los ntawm ib lub router mus rau lwm qhov siv Ansible;
3. Cia peb tham txog automation ntawm IT infrastructure tag nrho.

Network daim duab thiab piav qhia

Lub tswv yim

Cia peb xav txog cov duab kos duab ntawm peb lub koom haum. Peb yuav tsis tso npe rau cov tuam txhab tsim khoom tshwj xeeb; rau lub hom phiaj ntawm tsab xov xwm no nws tsis muaj teeb meem (Tus neeg nyeem nyeem yuav twv seb yam khoom siv twg yog siv). Qhov no tsuas yog ib qho zoo ntawm kev ua haujlwm nrog Ansible; thaum teeb tsa, peb feem ntau tsis quav ntsej yam khoom siv li cas. Tsuas yog kom nkag siab, qhov no yog cov khoom siv los ntawm cov neeg muag khoom paub zoo, xws li Cisco, Juniper, Check Point, Fortinet, Palo Alto ... koj tuaj yeem hloov koj tus kheej kev xaiv.

Peb muaj ob lub luag haujlwm tseem ceeb rau kev txav mus los:

1. Xyuas kom muaj kev tshaj tawm ntawm peb cov kev pabcuam, uas yog lub tuam txhab kev lag luam;
2. Muab kev sib txuas lus nrog cov ceg ntoo, cov chaw nyob deb nroog thiab cov koom haum thib peb (cov koom tes thiab cov neeg siv khoom), nrog rau kev nkag mus rau cov ceg ntoo hauv Is Taws Nem los ntawm lub hauv paus chaw ua haujlwm.

Cia peb pib nrog cov ntsiab lus tseem ceeb:

1. Ob tug ciam teb routers (BRD-01, BRD-02);
2. Firewall Cluster (FW-CLUSTER);
3. Core hloov (L3-CORE);
4. Ib lub router uas yuav dhau los ua txoj sia (raws li peb daws qhov teeb meem, peb yuav hloov lub network teeb tsa los ntawm FW-CLUSTER mus rau EMERGENCY) (EMERGENCY);
5. Hloov rau kev tswj hwm kev lag luam hauv network (L2-MGMT);
6. Lub tshuab virtual nrog Git thiab Ansible (VM-AUTOMATION);
7. Lub laptop uas kuaj thiab txhim kho cov ntawv ua si rau Ansible (Laptop-Automation) tau ua.

Lub network tau teeb tsa nrog OSPF routing raws tu qauv nrog cov hauv qab no:

• Thaj Chaw 0 - thaj chaw uas suav nrog cov routers lub luag haujlwm rau kev txav mus los hauv thaj chaw EXCHANGE;
• Thaj Chaw 1 - thaj chaw uas suav nrog cov routers lub luag haujlwm rau kev ua haujlwm ntawm tuam txhab kev pabcuam;
• Thaj Chaw 2 - thaj chaw uas suav nrog cov routers lub luag haujlwm rau kev tswj xyuas kev khiav tsheb;
• Thaj Chaw N - thaj chaw ntawm ceg tes hauj lwm.

Ntawm ciam teb routers, ib tug virtual router (VRF-INTERNET) yog tsim, nyob rau hauv uas eBGP tag nrho saib yog ntsia nrog cov coj AS. iBGP yog configured ntawm VRFs. Lub tuam txhab muaj cov chaw nyob dawb uas tau luam tawm ntawm VRF-INTERNET no. Qee qhov chaw nyob dawb raug xa ncaj qha mus rau FW-CLUSTER (qhov chaw nyob uas lub tuam txhab cov kev pabcuam ua haujlwm), qee qhov raug xa mus los ntawm thaj chaw EXCHANGE (cov kev pabcuam hauv tuam txhab uas xav tau chaw nyob IP sab nraud, thiab chaw nyob sab nraud NAT rau chaw ua haujlwm). Tom ntej no, cov tsheb khiav mus rau virtual routers tsim ntawm L3-CORE nrog chaw nyob dawb thiab grey (qhov chaw nyab xeeb).

Kev Tswj Xyuas Network siv cov keyboards tshwj xeeb thiab sawv cev rau lub cev rau lub cev. Kev tswj xyuas network kuj tau muab faib ua thaj chaw ruaj ntseg.
Lub EMERGENCY router lub cev thiab qhov laj thawj duplicates FW-CLUSTER. Tag nrho cov interfaces ntawm nws yog neeg xiam oob qhab tsuas yog cov uas saib mus rau hauv lub network tswj.

Automation thiab nws cov lus piav qhia

Peb paub tias lub network ua haujlwm li cas. Tam sim no cia peb ua ib kauj ruam los ntawm kev saib seb peb yuav ua li cas txhawm rau hloov tsheb los ntawm FW-CLUSTER mus rau EMERGENCY:

1. Peb lov tes taw cov kev sib tshuam ntawm cov tub ntxhais hloov (L3-CORE) uas txuas rau FW-CLUSTER;
2. Peb lov tes taw cov interfaces ntawm L2-MGMT ntsiav hloov uas txuas rau FW-CLUSTER;
3. Peb teeb tsa lub EMERGENCY router (los ntawm lub neej ntawd, txhua qhov kev cuam tshuam cuam tshuam rau nws, tshwj tsis yog cov cuam tshuam nrog L2-MGMT):

• Peb pab cuam cuam tshuam rau thaum muaj xwm ceev;
• Peb teeb tsa tus IP chaw nyob sab nraud (rau NAT) uas nyob ntawm FW-Cluster;
• Peb tsim gARP thov kom cov chaw nyob poppy nyob rau hauv L3-CORE arp ntxhuav hloov los ntawm FW-Cluster rau EMERGENCY;
• Peb tso npe rau txoj hauv kev zoo li qub rau BRD-01, BRD-02;
• Tsim NAT cov cai;
• Nce mus rau EMERGENCY OSPF Cheeb Tsam 1;
• Nce mus rau EMERGENCY OSPF Cheeb Tsam 2;
• Peb hloov tus nqi ntawm txoj kev hauv cheeb tsam 1 txog 10;
• Peb hloov tus nqi ntawm txoj kev nyob rau hauv cheeb tsam 1 txog 10;
• Peb hloov qhov chaw nyob IP cuam tshuam nrog L2-MGMT (rau cov uas nyob hauv FW-CLUSTER);
• Peb tsim gARP thov kom cov chaw nyob poppy hauv L2-MGMT arp cov lus hloov pauv los ntawm FW-CLUSTER mus rau EMERGENCY.

Ib zaug ntxiv, peb rov qab mus rau qhov qub formulation ntawm qhov teeb meem. Peb teev sawv ntxov, kev ntxhov siab loj, kev ua yuam kev ntawm txhua theem tuaj yeem ua rau muaj teeb meem tshiab. Npaj los ntaus cov lus txib ntawm CLI? Yog? Ok, tsawg kawg mus yaug koj lub ntsej muag, haus kas fes thiab sau koj lub siab nyiam.
Bruce, thov pab cov hais mav.

Zoo, peb txuas ntxiv txhim kho peb cov automation.
Hauv qab no yog daim duab qhia txog yuav ua li cas cov phau ntawv ua haujlwm hauv Ansible cov ntsiab lus. Cov tswv yim no qhia txog qhov peb tau piav qhia saum toj no, nws tsuas yog kev siv tshwj xeeb hauv Ansible.


Nyob rau theem no, peb paub tias yuav tsum tau ua dab tsi, tsim ib phau ntawv ua si, ua qhov kev sim, thiab tam sim no peb npaj los tso tawm.

Lwm me me lyrical digression. Qhov yooj yim ntawm zaj dab neeg yuav tsum tsis txhob dag koj. Cov txheej txheem ntawm kev sau phau ntawv playbook tsis yooj yim thiab ceev li nws zoo li. Kev sim tau siv sijhawm ntau heev, lub chaw muag khoom virtual tau tsim, kev daws teeb meem tau sim ntau zaus, txog 100 qhov kev sim tau ua tiav.

Cia peb pib ... Muaj kev xav tias txhua yam tshwm sim maj mam, muaj qhov yuam kev qee qhov, qee yam yuav tsis ua haujlwm thaum kawg. Kev xav ntawm kev dhia nrog lub parachute, tab sis lub parachute tsis xav qhib tam sim ntawd ... qhov no yog qhov qub.

Tom ntej no, peb nyeem cov txiaj ntsig ntawm kev ua haujlwm ntawm Ansible playbook (tus IP chaw nyob tau hloov pauv rau lub hom phiaj ntawm kev zais cia):

PLAY RECAP ************************************************************************

Ua tiav!

Qhov tseeb, nws tsis tau npaj txhij, tsis txhob hnov ​​​​qab txog kev sib koom ua ke ntawm cov txheej txheem dynamic routing thiab thauj ntau txoj hauv kev mus rau FIB. Peb tsis tuaj yeem cuam tshuam qhov no hauv txhua txoj kev. Peb tos. Nws ua haujlwm tawm. Tam sim no nws npaj txhij.

Thiab nyob rau hauv lub zos Vilabajo (uas tsis xav kom automate lub network teeb) lawv txuas ntxiv ntxuav tais diav. Bruce (tau lees paub, twb sib txawv, tab sis tsis muaj tsawg dua txias) tab tom sim nkag siab ntau npaum li cas phau ntawv hloov kho ntawm cov cuab yeej yuav tshwm sim.

Kuv kuj xav nyob ntawm ib qho tseem ceeb. Peb tuaj yeem tau txais txhua yam rov qab li cas? Tom qab qee lub sijhawm, peb yuav coj peb FW-CLUSTER rov qab los ua neej. Qhov no yog cov cuab yeej tseem ceeb, tsis yog thaub qab, lub network yuav tsum khiav ntawm nws.

Koj puas xav tias networkers pib hlawv tawm? Tus thawj coj kev tshaj lij yuav hnov ​​​​ib txhiab lus sib cav vim li cas qhov no yuav tsum tsis ua, vim li cas qhov no tuaj yeem ua tiav tom qab. Hmoov tsis zoo, qhov no yog li cas lub network ua haujlwm los ntawm ib pawg ntawm thaj ua rau thaj, daim, thiab cov seem ntawm nws cov khoom kim heev qub. Nws hloov tawm los ua patchwork quilt. Peb txoj hauj lwm feem ntau, tsis yog nyob rau hauv cov xwm txheej tshwj xeeb no, tab sis feem ntau ntawm cov hauv paus ntsiab lus, raws li cov kws tshaj lij IT, yog coj cov haujlwm ntawm lub network mus rau cov lus Askiv zoo nkauj "kev sib raug zoo", nws yog ntau yam, nws tuaj yeem txhais tau tias: kev sib koom ua ke. , sib xws, logic, coherence, systematicity, comparability, coherence. Nws yog txhua yam hais txog nws. Tsuas yog nyob rau hauv lub xeev no yog lub network tswj tau, peb kom meej meej to taub dab tsi ua hauj lwm thiab yuav ua li cas, peb kom meej meej to taub dab tsi yuav tsum tau hloov, yog tias tsim nyog, peb kom meej meej paub qhov twg yuav saib yog hais tias muaj teeb meem tshwm sim. Thiab tsuas yog nyob rau hauv xws li ib tug network koj muaj peev xwm ua tricks zoo li cov uas peb nyuam qhuav piav.

Qhov tseeb, lwm phau ntawv ua si tau npaj, uas xa rov qab cov chaw rau lawv lub xeev qub. Lub logic ntawm nws txoj haujlwm yog tib yam (nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias qhov kev txiav txim ntawm kev ua haujlwm tseem ceeb heev), txhawm rau kom tsis txhob ncua ib tsab xov xwm ntev lawm, peb txiav txim siab tsis tshaj tawm cov npe ntawm cov ntawv ua tiav. Tom qab ua qhov kev tawm dag zog zoo li no, koj yuav hnov ​​​​zoo dua thiab muaj kev ntseeg siab dua yav tom ntej, ntxiv rau, txhua tus ntoo khaub lig uas koj tau muab tso rau ntawd yuav nthuav tawm lawv tus kheej tam sim ntawd.

Leej twg tuaj yeem sau ntawv rau peb thiab tau txais cov peev txheej ntawm tag nrho cov ntawv sau, nrog rau tag nrho cov phau ntawv paly. Hu rau hauv profile.

tshawb pom

Hauv peb lub tswv yim, cov txheej txheem uas tuaj yeem ua haujlwm tsis tau muaj crystallized. Raws li qhov peb tau ntsib thiab qhov uas peb cov npoj yaig sab hnub poob tab tom tham, cov ntsiab lus hauv qab no tau pom txog tam sim no:

• Kev npaj khoom siv;
• Kev sau cov ntaub ntawv;
• Qhia;
• Kev daws teeb meem;
• Kev Ua Raws Cai.

Yog tias muaj kev txaus siab, peb tuaj yeem txuas ntxiv qhov kev sib tham ntawm ib qho ntawm cov ncauj lus.

Kuv kuj xav tham me ntsis txog automation. Dab tsi nws yuav tsum yog hauv peb txoj kev nkag siab:

• Lub kaw lus yuav tsum nyob tsis muaj ib tug neeg, thaum raug txhim kho los ntawm ib tug neeg. Lub kaw lus yuav tsum tsis txhob nyob ntawm tib neeg;
• Kev ua haujlwm yuav tsum yog tus kws tshaj lij. Tsis muaj chav kawm tshwj xeeb uas ua cov haujlwm niaj hnub ua. Muaj cov kws tshaj lij uas tau ua haujlwm txhua lub sijhawm thiab daws cov teeb meem nyuaj nkaus xwb;
• Cov haujlwm niaj hnub ua haujlwm tau ua tiav "ntawm qhov kov ntawm lub pob", tsis muaj peev txheej pov tseg. Qhov tshwm sim ntawm cov haujlwm zoo li no yog ib txwm kwv yees thiab nkag siab.

Thiab cov ntsiab lus no yuav ua li cas rau:

• Transparency ntawm IT infrastructure (tsawg txaus ntshai ntawm kev khiav hauj lwm, modernization, siv. Tsawg downtime ib xyoos);
• Lub peev xwm los npaj IT cov peev txheej (Lub peev xwm-txhim kho qhov system - koj tuaj yeem pom ntau npaum li cas tau siv, koj tuaj yeem pom ntau npaum li cas cov peev txheej yuav tsum tau muaj nyob rau hauv ib qho system, thiab tsis yog los ntawm cov ntawv thiab mus ntsib cov tuam tsev sab saum toj);
• Muaj peev xwm txo cov neeg ua haujlwm IT.

Cov sau phau ntawv: Alexander Chelovekov (CCIE RS, CCIE SP) thiab Pavel Kirillov. Peb txaus siab los tham thiab tawm tswv yim daws teeb meem ntawm lub ncauj lus ntawm IT infrastructure automation.
