Ekuhlanganiseni kwethu kwenethiwekhi yendawo sibe namapheya ayisithupha okushintsha kwe-Arista DCS-7050CX3-32S kanye nepheya elilodwa lamaswishi e-Brocade VDX 6940-36Q. Akukhona ukuthi besicindezelwe ngokweqile amaswishi e-Brocade kule nethiwekhi, ayasebenza futhi enza imisebenzi yawo, kodwa besilungiselela ukwenza okuzenzakalelayo okugcwele kwezinye izenzo, futhi besingenawo lawa makhono kulawa maswishi. Bengifuna nokushintsha kusuka ku-40GE interfaces ngisebenzise i-100GE ukuze ngenze indawo yokugcina iminyaka engu-2-3 elandelayo. Ngakho-ke sanquma ukushintsha i-Brocade ibe yi-Arista.
Lawa maswishi amaswishi ahlanganisiwe e-LAN esikhungo ngasinye sedatha. Amaswishi okusabalalisa (izinga lesibili lokuhlanganisa) axhunywe kuwo ngokuqondile, asevele ehlanganisa amaswishi enethiwekhi yendawo ye-Top-of-Rack kuma-rack anamaseva.
Iseva ngayinye ixhunywe kusishintshi sokufinyelela esisodwa noma ezimbili. Amaswishi okufinyelela axhunywe kumaswishi amabili okusabalalisa (amaswishi amabili okusabalalisa kanye nezixhumanisi ezimbili ezibonakalayo ukusuka ekushintsheni kokufinyelela kuya kumaswishi okusabalalisa ahlukene asetshenziselwa ukuphinda asetshenziswe).
Iseva ngayinye ingasetshenziswa iklayenti layo, ngakho iklayenti labelwa i-VLAN ehlukile. I-VLAN efanayo ibe ibhalisiwe kwenye iseva yaleli klayenti kunoma iyiphi i-rack. Isikhungo sedatha siqukethe imigqa eminingana enjalo (ama-POD), umugqa ngamunye wama-rack unamaswishi awo okusabalalisa. Bese lezi zinguquko zokusabalalisa zixhunywa kumaswishi okuhlanganisa.
Amaklayenti angakwazi uku-oda iseva kunoma yimuphi umugqa; akunakwenzeka ukubikezela kusengaphambili ukuthi iseva izokwabelwa noma ifakwe kumugqa othize ku-rack ethile, yingakho kunama-VLAN angaba ngu-2500 ekushintsheni kokuhlanganisa esikhungweni ngasinye sedatha.
Okokusebenza kwe-DCI (I-Data-Center Interconnect) ixhunywe kumaswishi ahlanganisayo. Ingahloselwe ukuxhumana kwe-L2 (amaswishi amabili akha umhubhe we-VXLAN oya kwesinye isikhungo sedatha) noma ukuxhumana kwe-L3 (amarutha amabili e-MPLS).
Njengoba ngike ngabhala, ukuhlanganisa izinqubo zokuzenzakalela ukucushwa kwezinsizakalo kumishini esikhungweni esisodwa sedatha, kwakudingeka ukuthi kushintshwe amaswishi okuhlanganisa amaphakathi. Safaka amaswishi amasha eduze kwalawo akhona, sawahlanganisa abe yipheya ye-MLAG futhi saqala ukulungiselela umsebenzi. Axhunywe ngokushesha kumaswishi okuhlanganisa akhona, ukuze abe nesizinda esivamile se-L2 kuwo wonke ama-VLAN eklayenti.
Imininingwane yesifunda
Ngokucaciswa, ake sisho amaswishi amadala wokuhlanganisa I-Π1 ΠΈ I-Π2, okusha - N1 ΠΈ N2. Ake sikucabange lokho I-POD 1 ΠΈ I-POD 4 amaseva eklayenti elilodwa asingathwa Π‘1,I-VLAN yeklayenti ikhonjiswe ngokuluhlaza okwesibhakabhaka. Leli klayenti lisebenzisa isevisi yokuxhumana ye-L2 nesinye isikhungo sedatha, ngakho i-VLAN yalo inikezwa amaswishi e-VXLAN.
Ikhasimende Π‘2 ibamba amaseva ku I-POD 2 ΠΈ I-POD 3, I-VLAN yeklayenti ichazwa ngokuluhlaza okumnyama. Leli klayenti futhi lisebenzisa isevisi yokuxhuma nesinye isikhungo sedatha, kodwa i-L3, ngakho i-VLAN yalo inikezwa amarutha amabili e-L3VPN.
Sidinga ama-VLAN eklayenti ukuze siqonde ukuthi yiziphi izigaba zomsebenzi oshintshwayo ukuthi kwenzekani, lapho ukuphazamiseka kokuxhumana kwenzeka, nokuthi ubude bayo bungaba bungakanani. I-protocol ye-STP ayisetshenziswanga kulolu hlelo, njengoba ububanzi besihlahla kulo kuleli cala bukhulu, futhi ukuhlangana kwephrothokholi kukhula ngokuqhubekayo ngenani lamadivayisi nezixhumanisi phakathi kwazo.
Wonke amadivayisi axhunywe ngezixhumanisi ezimbili akha isitaki, ipheya ye-MLAG noma indwangu ye-VCS Ethernet. Kuma-router e-L3VPN, ubuchwepheshe obunjalo abusetshenziswa, njengoba asikho isidingo sokuphindaphinda kwe-L2; kwanele ukuthi banokuxhuma kwe-L2 komunye nomunye ngokushintsha kokuhlanganisa.
Izinketho zokuqalisa
Lapho sihlaziya izinketho zemicimbi eyengeziwe, sabona ukuthi kunezindlela eziningana zokwenza lo msebenzi. Ukusuka ekunqamukeni komhlaba wonke kuyo yonke inethiwekhi yendawo, kuya kumakhefu amancane amasekhondi angu-1-2 ezingxenyeni zenethiwekhi.
Inethiwekhi, yeka! Shintsha, shintsha!
Indlela elula, vele, ukumemezela ikhefu lokuxhumana emhlabeni wonke kuwo wonke ama-POD nazo zonke izinsizakalo ze-DCI futhi ushintshe zonke izixhumanisi kusuka kumaswishi. Π kumaswishi N.
Ngaphandle kokuphazamiseka, isikhathi esingeke sikwazi ukubikezela ngaso ngokuthembekile (yebo, siyalazi inani lezixhumanisi, kodwa asazi ukuthi into izohamba kabi kangaki - ukusuka entanjeni yesichibi ephukile noma isixhumi esilimele siye embobeni engalungile noma i-transceiver. ), asikwazi ukubikezela kusengaphambili ukuthi ubude bezintambo ze-patch, i-DAC, i-AOC, exhunywe kuma-switch endala A, buyokwanela ukuwafinyelela ekushintsheni okusha N, nakuba emi eduze kwabo, kodwa namanje kancane ukuze ohlangothini, nokuthi ngabe ama-transceivers afanayo azosebenza / i-DAC/AOC kusuka ekushintsheni kwe-Brocade kuya ekushintsheni kwe-Arista.
Futhi konke lokhu ngaphansi kwezimo zengcindezi enzima evela kumakhasimende kanye nokusekelwa kwezobuchwepheshe ("Natasha, vuka! Natasha, yonke into ayisebenzi lapho! UNatasha, sesivele sibhalele ukusekelwa kwezobuchwepheshe, ngokwethembeka! UNatasha, sebevele belahle yonke into ! Natasha, bangaki abanye esingeke sisebenze? Natasha, izosebenza nini?!"). Ngisho naphezu kwekhefu elimenyezelwe ngaphambilini kanye nesaziso kumakhasimende, ukuthutheleka kwezicelo ngaleso sikhathi kuqinisekisiwe.
Yima, 1-2-3-4!
Kuthiwani uma singamemezeli ikhefu lomhlaba wonke, kodwa kunalokho uchungechunge lweziphazamiso ezincane zokuxhumana ze-POD nezinsizakalo ze-DCI. Ngesikhathi sekhefu lokuqala, shintshela kumaswishi N kuphela I-POD 1, okwesibili - ezinsukwini ezimbalwa - I-POD 2, bese kuba izinsuku ezimbalwa I-POD 3, Ngaphezu kwalokho I-POD 4β¦[N], bese ishintsha i-VXLAN bese kuba amarutha e-L3VPN.
Ngale nhlangano yokushintsha umsebenzi, sinciphisa inkimbinkimbi yomsebenzi wesikhathi esisodwa futhi sandise isikhathi sethu sokuxazulula izinkinga uma kukhona okungahambi kahle ngokuzumayo. I-POD 1 ihlala ixhumekile kwamanye ama-POD nama-DCI ngemva kokushintsha. Kodwa umsebenzi ngokwawo udonsa isikhathi eside; phakathi nalo msebenzi esikhungweni sedatha, unjiniyela uyadingeka ukuba enze ushintsho ngokomzimba, futhi ngesikhathi somsebenzi (futhi umsebenzi onjalo wenziwa, njengomthetho, ebusuku, kusukela ku-2 kuya ku-5 am), ukuba khona kukanjiniyela wenethiwekhi ye-inthanethi kuyadingeka ezingeni eliphezulu kakhulu leziqu. Kodwa-ke sithola ukuphazamiseka okufushane kokuxhumana; njengomthetho, umsebenzi ungenziwa kungakapheli isigamu sehora ngekhefu elifinyelela kumaminithi angu-2 (ngokuprakthiza, ngokuvamile imizuzwana engu-20-30 ngokuziphatha okulindelekile kwemishini).
Esibonelweni seklayenti Π‘1 noma iklayenti Π‘2 kuzodingeka uxwayise ngomsebenzi ngokuphazanyiswa kokuxhumana okungenani izikhathi ezintathu - okokuqala ukwenza umsebenzi ku-POD eyodwa, lapho enye yamaseva ayo ikhona, okwesibili - okwesibili, kanti okwesithathu - lapho ukushintsha okokusebenza kwezinsiza ze-DCI.
Ukushintsha iziteshi zokuxhumana ezihlanganisiwe
Kungani sikhuluma ngokuziphatha okulindelekile kwemishini, nokuthi iziteshi ezihlanganisiwe zingashintshwa kanjani kuyilapho kunciphisa ukuphazamiseka kokuxhumana? Ake sicabange ngesithombe esilandelayo:
Ngakolunye uhlangothi lwesixhumanisi kukhona ukushintshwa kokusabalalisa kwe-POD - D1 ΠΈ D2, bakha ipheya ye-MLAG nomunye nomunye (isitaki, imboni ye-VCS, i-vPC pair), ngakolunye uhlangothi kunezixhumanisi ezimbili - Xhumanisa i-1 ΠΈ Xhumanisa i-2 - kufakwe kupheya ye-MLAG yamaswishi amadala wokuhlanganisa Π. Ohlangothini lokushintsha D isixhumi esibonakalayo esihlanganisiwe esinegama I-Port-channel A, ohlangothini lwamaswishi okuhlanganisa Π - interface ehlanganisiwe enegama I-Port-channel D.
Izixhumanisi ezihlanganisiwe zisebenzisa i-LACP ekusebenzeni kwazo, okungukuthi, amaswishi nhlangothi zombili ashintshana njalo amaphakethe e-LACPDU kuzo zombili izixhumanisi ukuze aqinisekise ukuthi izixhumanisi:
- abasebenzi;
- kufakwe kudivayisi eyodwa kuhlangothi olukude.
Lapho ushintsha amaphakethe, iphakethe liphethe inani i-id yesistimu, okubonisa idivayisi lapho lezi zixhumanisi zifakwe khona. Kupheya ye-MLAG (isitaki, imboni, njll.), inani le-id yesistimu lamadivayisi akha isixhumi esibonakalayo esihlanganisiwe liyafana. Shintsha D1 ithumela ku Xhumanisa i-1 okusho uhlelo-id D, futhi ushintshe D2 ithumela ku Xhumanisa i-2 okusho uhlelo-id D.
Ukushintsha I-Π1 ΠΈ I-Π2 hlaziya amaphakethe e-LACPDU atholwe ngaphezu kwesixhumi esibonakalayo se-Po D futhi uhlole ukuthi i-id yesistimu kuwo iyahambisana yini. Uma i-id yesistimu etholwe ngesixhumanisi esithile ishintsha ngokuzumayo kusuka kunani lokusebenza lamanje, bese lesi sixhumanisi siyasuswa kusixhumi esibonakalayo esihlanganisiwe kuze kube yilapho isimo sesilungisiwe. Manje ohlangothini lwethu lokushintsha D inani lamanje le-id yesistimu evela kuzakwethu we-LACP - A, nasohlangothini lokushintsha Π - inani lamanje le-id yesistimu evela kuzakwethu we-LACP - D.
Uma sidinga ukushintsha isixhumi esibonakalayo esihlanganisiwe, singakwenza ngezindlela ezimbili ezihlukene:
Indlela 1 - Ilula
Khubaza zombili izixhumanisi kumaswishi A. Kulokhu, isiteshi esihlanganisiwe asisebenzi.
Xhuma zombili izixhumanisi ngayinye ngayinye kumaswishi N, khona-ke imingcele yokusebenza ye-LACP izoxoxisana futhi futhi isixhumi esibonakalayo sizokwakhiwa UPo D kumaswishi N kanye nokudluliselwa kwamanani kuzixhumanisi uhlelo-id N.
Indlela yesi-2 - Nciphisa ukuphazamiseka
Nqamula i-Link 2 ekushintsheni i-A2. Ngesikhathi esifanayo, traffic phakathi Π ΠΈ D izoqhubeka nokudluliselwa kalula ngesixhumanisi esisodwa, esizohlala siyingxenye yesixhumi esibonakalayo esihlanganisiwe.
Xhuma i-Link 2 ukuze ushintshe i-N2. Ekushintsheni N isixhumi esibonakalayo esihlanganisiwe sesivele simisiwe Nge-DN, futhi ushintshe N2 izoqala ukudlulisela ku-LACPDU uhlelo-id N. Kulesi sigaba sesingakwazi kakade ukuhlola ukuthi ukushintsha N2 isebenza kahle ne-transceiver esetshenziselwe yona Xhumanisa i-2, ukuthi imbobo yokuxhumana ingene kusimo Up, nokuthi awekho amaphutha avelayo embobeni yokuxhuma lapho kuthunyelwa ama-LACPDU.
Kodwa iqiniso lokuthi ukushintsha D2 kokusebenzelana okuhlanganisiwe UPo A kusukela ohlangothini Isixhumanisi 2 sithola inani le-id yesistimu elihlukile kunani lamanje le-id yesistimu yokusebenza, ayikuvumeli ukushintsha D ukwethula Xhumanisa i-2 ingxenye yesixhumi esibonakalayo esihlanganisiwe UPo A. Shintsha N ayikwazi ukungena Xhumanisa i-2 iqala ukusebenza, njengoba ingasitholi isiqinisekiso sokusebenza esivela kuzakwethu we-LACP weswishi D2. Ithrafikhi ewumphumela ingu Xhumanisa i-2 engadluli.
Futhi manje sivala i-Link 1 ekushintsheni i-A1, ngaleyo ndlela incisha amaswishi Π ΠΈ D isikhombimsebenzisi esisebenzayo. Ngakho ohlangothini lokushintsha D inani lamanje le-id yesistimu yokusebenza yesixhumi esibonakalayo liyanyamalala UPo A.
Lokhu kuvumela amaswishi D ΠΈ N vuma ukushintshanisa i-id yesistimu AN kuma-interface UPo A ΠΈ Nge-DN, ukuze ithrafikhi iqale ukudluliselwa eduze kwesixhumanisi Xhumanisa i-2. Ikhefu kuleli cala, ekusebenzeni, lifika kumasekhondi angu-2.
Futhi manje singashintsha kalula i-Link 1 ukuze sishintshe i-N1, ukubuyisela amandla kanye nezinga lokungadingeki kwesixhumi esibonakalayo UPo A ΠΈ Nge-DN. Kusukela lapho lesi sixhumanisi sixhunyiwe, inani lamanje le-id yesistimu alishintshi nhlangothi zombili, akukho ukuphazamiseka.
Izixhumanisi ezengeziwe
Kodwa ukushintshwa kungenziwa ngaphandle kokuba khona kukanjiniyela ngesikhathi sokushintsha. Ukuze senze lokhu, sizodinga ukubeka izixhumanisi ezengeziwe phakathi kwamaswishi okusabalalisa kusengaphambili D namaswishi amasha okuhlanganisa N.
Sibeka izixhumanisi ezintsha phakathi kwamaswishi okuhlanganisa N namaswishi okusabalalisa awo wonke ama-POD. Lokhu kudinga uku-oda nokubeka izintambo zokuvala ezengeziwe, kanye nokufaka ama-transceiver engeziwe njengaku N, futhi D. Lokhu singakwenza ngoba ekushintsheni kwethu D I-POD ngayinye inezimbobo zamahhala (noma sizikhulula kusengaphambili). Ngenxa yalokho, i-POD ngayinye ixhunywe ngokoqobo ngezixhumanisi ezimbili ezishintshayo ezindala A kanye nezishintshayo ezintsha ezingu-N.
Ekushintsheni D kwakhiwe ama-interface amabili ahlanganisiwe - UPo A ngezixhumanisi Xhumanisa i-1 ΠΈ Xhumanisa i-2futhi UPo N - ngezixhumanisi Xhumanisa i-N1 ΠΈ Xhumanisa i-N2. Kulesi sigaba, sibheka ukuxhumana okulungile kwezixhumanisi zokusebenzelana nezixhumanisi, amazinga amasignali optical kuzo zombili iziphetho zezixhumanisi (ngolwazi lwe-DDM oluvela kumaswishi), singahlola ngisho nokusebenza kwesixhumanisi ngaphansi komthwalo noma siqaphe izifundazwe. amasignali optical namazinga okushisa e-transceiver izinsuku ezimbalwa.
Ithrafikhi isathunyelwa nge-interface UPo A, kanye nesixhumi esibonakalayo UPo N kubiza akukho traffic. Izilungiselelo ezinkundleni zokuxhumana zimi kanje:
Interface Port-channel A
Switchport mode trunk
Switchport allowed vlan C1, C2
Interface Port-channel N
Switchport mode trunk
Switchport allowed vlan noneUkushintsha kuka-D, njengomthetho, izinguquko zokucushwa okusekelwe kuseshini yosekelo; shintsha amamodeli analokhu kusebenza asetshenziswa. Ngakho-ke singashintsha izilungiselelo ze-Po A ne-Po N ngesinyathelo esisodwa:
Configure session
Interface Port-channel A
Switchport allowed vlan none
Interface Port-channel N
Switchport allowed vlan C1, C2
CommitKhona-ke ukuguqulwa kokucushwa kuzokwenzeka ngokushesha ngokwanele, futhi ikhefu ngeke, ekusebenzeni, lingabi ngaphezu kwamasekhondi angu-5.
Le ndlela isivumela ukuthi siqedele wonke umsebenzi wokulungiselela kusengaphambili, senze wonke amasheke adingekayo, sixhumanise umsebenzi nabahlanganyeli kule nqubo, sibikezele ngokuningiliziwe izenzo zokukhiqiza umsebenzi, ngaphandle kwezindiza zokudala lapho "konke kungalungile. ,β futhi ube necebo eliseduze lokubuyela ekucushweni kwangaphambilini. Ukusebenza ngokwalolu hlelo kwenziwa unjiniyela wenethiwekhi ngaphandle kokuba khona kukanjiniyela wesikhungo sedatha esizeni oshintshayo ngokoqobo.
Okubalulekile futhi ngale ndlela yokushintsha ukuthi zonke izixhumanisi ezintsha sezivele ziqashwe kusengaphambili. Amaphutha, ukufakwa kwezixhumanisi kuyunithi, ukulayishwa kwezixhumanisi - lonke ulwazi oludingekayo seluvele lukhona ohlelweni lokuqapha, futhi lokhu sekuvele kudwetshiwe kumamephu.
D-Day
IPOD
Sikhethe indlela yokushintsha ebuhlungu kakhulu kumakhasimende kanye nezimo ezithambekele kakhulu βezinokuthile okungahambanga kahleβ ezinezixhumanisi ezengeziwe. Ngakho-ke sishintshe wonke ama-POD kumaswishi amasha okuhlanganisa ngobusuku obumbalwa.
Kodwa okusele wukushintsha imishini ehlinzeka ngezinsizakalo ze-DCI.
L2
Endabeni yemishini ehlinzeka ngokuxhumeka kwe-L2, asikwazanga ukwenza umsebenzi ofanayo ngezixhumanisi ezengeziwe. Kunezizathu okungenani ezimbili zalokhu:
- Ukushoda kwezimbobo zamahhala zejubane elidingekayo kumaswishi e-VXLAN.
- Ukuntuleka kokusebenza koshintsho lokucushwa kweseshini kumaswishi e-VXLAN.
Asizange sishintshe izixhumanisi βkanye ngesikhathiβ ngekhefu kuphela ngenkathi sivumelana ngepheya ye-id yesistimu entsha, njengoba sasingenalo ithemba elingu-100% lokuthi inqubo izohamba kahle, futhi ukuhlolwa elabhorethri kwabonisa ukuthi uma "okuthile kungahambi kahle," sisathola ukuphazamiseka kokuxhumeka, futhi okubi kakhulu akukhona nje kumakhasimende anokuxhumana kwe-L2 nezinye izikhungo zedatha, kodwa ngokuvamile kuwo wonke amaklayenti alesi sikhungo sedatha.
Senze umsebenzi we-propaganda kusenesikhathi ekushintsheni kusuka eziteshini ze-L2, ngakho inani lamakhasimende athintwa umsebenzi wokushintshwa kwe-VXLAN lase livele izikhathi ezimbalwa ngaphansi konyaka odlule. Ngenxa yalokho, sinqume ukuphazamisa ukuxhumana ngesevisi yokuxhuma i-L2, inqobo nje uma sigcina ukusebenza okuvamile kwezinsizakalo zenethiwekhi yendawo esikhungweni esisodwa sedatha. Ngaphezu kwalokho, i-SLA yale nsizakalo ihlinzekela ukuthi kungenzeka ukwenza umsebenzi ohleliwe ngokuphazanyiswa.
L3
Kungani sincome ukuthi wonke umuntu ashintshele ku-L3VPN lapho ehlela izinsiza ze-DCI? Esinye sezizathu yikhono lokwenza umsebenzi kwenye yamarutha ahlinzeka ngale nsizakalo, ngokumane wehlise izinga lokuphinda libe ngu-N+0, ngaphandle kokuphazamisa ukuxhumana.
Ake sibhekisise kahle uhlelo lokulethwa kwezinsiza. Kule sevisi, ingxenye ye-L2 isuka kumaseva eklayenti kuphela iye kumarutha we-L3VPN Selectel. Inethiwekhi yeklayenti inqanyuliwe kumarutha.
Iseva yeklayenti ngayinye, isb. S2 ΠΈ S3 emdwebeni ongenhla, banamakheli abo e-IP ayimfihlo - 10.0.0.2/24 kuseva S2 ΠΈ 10.0.0.3/24 kuseva S3. Amakheli 10.0.0.252/24 ΠΈ 10.0.0.253/24 inikezwe i-Selectel kumarutha I-L3VPN-1 ΠΈ I-L3VPN-2, ngokulandelana. Ikheli le-IP 10.0.0.254/24 ikheli le-VRRP VIP kuma-router e-Selectel.
Ungafunda kabanzi mayelana nesevisi ye-L3VPN kubhulogi yethu.
Ngaphambi kokushintsha, yonke into yayibukeka njengoba kumdwebo:
Amarutha amabili I-L3VPN-1 ΠΈ I-L3VPN-2 axhunywe kusishintshi esidala sokuhlanganisa Π. Inkosi yekheli le-VRRP VIP elithi 10.0.0.254 irutha I-L3VPN-1. Inokubaluleka okuphezulu kwaleli kheli kunerutha I-L3VPN-2.
unit 1006 {
description C2;
vlan-id 1006;
family inet {
address 10.0.0.252/24 {
vrrp-group 1 {
priority 200;
virtual-address 10.100.0.254;
preempt {
hold-time 120;
}
accept-data;
}
}
}
}Iseva ye-S2 isebenzisa isango elingu-10.0.0.254 ukuze ixhumane namaseva kwezinye izindawo. Ngakho, ukunqamula umzila we-L3VPN-2 kunethiwekhi (yebo, uma inqanyulwa okokuqala esizindeni se-MPLS) akuthinti ukuxhumeka kwamaseva eklayenti. Kuleli qophelo, izinga lokuphindaphinda kwesekethe limane lincishiswe.
Ngemva kwalokhu singakwazi ukuxhuma kabusha i-router ngokuphephile I-L3VPN-2 kumaswishi amabili N. Faka izixhumanisi, shintsha ama-transceivers. I-interfaces enengqondo ye-router, lapho ukusebenza kwezinsizakalo zeklayenti kuncike khona, kuyacishwa kuze kuqinisekiswe ukuthi konke kusebenza ngendlela efanele.
Ngemva kokuhlola izixhumanisi, ama-transceivers, amazinga esignali, namazinga amaphutha ezindaweni ezihlanganayo, i-router ifakwa ekusebenzeni, kodwa isivele ixhunywe ku-pair entsha yokushintsha.
Okulandelayo, sehlisa ukubaluleka kwe-VRRP kumzila we-L3VPN-1, futhi ikheli le-VIP elithi 10.0.0.254 lihanjiswe kumzila we-L3VPN-2. Le misebenzi yenziwa ngaphandle kokuphazamiseka kokuxhumana.
Idlulisela ikheli le-VIP 10.0.0.254 kumzila I-L3VPN-2 ikuvumela ukuthi ukhubaze i-router I-L3VPN-1 ngaphandle kokuphazamiseka kokuxhumana kweklayenti bese ulixhuma epheya entsha yokushintsha kokuhlanganisa N.
Ukuthi ukubuyisela i-VRRP VIP kumzila we-L3VPN-1 noma cha kungomunye umbuzo, futhi ngisho noma ubuyiselwa, wenziwa ngaphandle kokuphazamisa uxhumano.
Inani
Ngemva kwazo zonke lezi zinyathelo, empeleni sishintshe ukushintsha kokuhlanganisa kwesinye sezikhungo zethu zedatha, kuyilapho sinciphisa ukuphazamiseka kumakhasimende ethu.
Okusele wukuhlakazwa. Ukuhlakazwa kwamaswishi amadala, ukuhlakazwa kwezixhumanisi ezindala phakathi kwama-switch A no-D, ukuhlakazwa kwama-transceiver kulezi zixhumanisi, ukulungiswa kokuqapha, ukulungiswa kwemidwebo yenethiwekhi ekubhalweni nasekuqaphelweni.
Singasebenzisa amaswishi, ama-transceivers, izintambo zokuchibiyela, i-AOC, i-DAC esele ngemva kokushintsha kwamanye amaphrojekthi noma okunye ukushintsha okufanayo.
"Natasha, sishintshe yonke into!"
