Kwi-aggregation yethu yenethiwekhi yendawo sasinezibini ezintandathu ze-Arista DCS-7050CX3-32S zokutshintsha kunye neperi enye ye-Brocade VDX 6940-36Q yokutshintsha. Akunjalo ukuba sigxininiswe ngokugqithiseleyo ngokutshintshwa kwe-Brocade kule nethiwekhi, bayasebenza kwaye benza imisebenzi yabo, kodwa sasilungiselela ukuzenzekelayo ngokupheleleyo kwezinye izenzo, kwaye sasingenalo obu buchule kwezi zitshintshi. Kwakhona ndandifuna ukutshintshela kwi-interfaces ye-40GE kwithuba lokusebenzisa i-100GE ukwenzela ukuba ndenze indawo yokugcina iminyaka eyi-2-3 elandelayo. Ngoko sagqiba ekubeni sitshintshe iBrocade ibe nguArista.
Olu tshintsho lutshintshiselwano lwe-LAN kwiziko ngalinye ledatha. Ukutshintshwa kokusasazwa (inqanaba lesibini lokudibanisa) liqhagamshelwe ngokuthe ngqo kubo, esele ihlanganise i-Top-of-Rack itshintshi yenethiwekhi yendawo kwiirack ezinamaseva.
Umncedisi ngamnye uqhagamshelwe kwiswitshi enye okanye ezimbini zofikelelo. Ukutshintshwa kokufikelela kuxhunyiwe kwibini yokutshintshwa kokusabalalisa (iinguqu ezimbini zokusabalalisa kunye neekhonkco ezimbini zomzimba ukusuka kwinguqu yokufikelela kwiinguqu ezahlukeneyo zokusabalalisa zisetyenziselwa ukuphindaphinda).
Umncedisi ngamnye unokusetyenziswa ngumxhasi wakhe, ngoko umxhasi unikwe iVLAN eyahlukileyo. I-VLAN efanayo ibhalisiwe kwenye iseva yalo mxhasi kuyo nayiphi na irack. Iziko ledatha liqukethe imigqa emininzi enjalo (ii-POD), umqolo ngamnye wee-rack unezitshintshi zawo zokusasaza. Emva koko ezi zitshintshi zokusasaza zixhunywe kwi-aggregation switches.
Abathengi banokuodola umncedisi kuwo nawuphi na umqolo, akunakwenzeka ukuqikelela kwangaphambili ukuba umncedisi uya kwabelwa okanye afakwe kumqolo othile kwirack ethile, ngoko kukho malunga ne-2500 VLAN kwi-aggregation switches kwiziko ledatha nganye.
Izixhobo ze-DCI (Uqhagamshelwano lweZiko leDatha) luqhagamshelwe kwiiswitshi ezidityanisiweyo. Inokuthi ihloselwe uxhulumaniso lwe-L2 (isibini sokutshintsha ukwenza itonela ye-VXLAN kwelinye iziko ledatha) okanye uqhagamshelwano lwe-L3 (ii-routers ezimbini ze-MPLS).
Njengoko sele ndibhalile, ukudibanisa iinkqubo zokuzenzekelayo ukucwangciswa kweenkonzo kwizixhobo kwiziko ledatha enye, kwakuyimfuneko ukutshintshwa kwe-central aggregation switches. Sifake iiswitshi ezintsha ecaleni kwezi zikhoyo, zidibanise kwisibini se-MLAG kwaye saqala ukulungiselela umsebenzi. Baye baqhagamshelwa ngoko nangoko kwiiswitshi zodityaniso ezikhoyo, ukuze babenendawo eqhelekileyo ye-L2 kuzo zonke ii-VLAN zabaxhasi.
Iinkcukacha zesekethe
Ngokucacileyo, masithi igama lotshintsho oludala lokudibanisa A1 ΠΈ A2, entsha - N1 ΠΈ N2. Makhe sicinge ukuba I-POD 1 ΠΈ I-POD 4 abancedisi bomxhasi omnye babanjiwe C1,Umxhasi weVLAN uboniswe ngombala oluhlaza. Lo mxhasi usebenzisa inkonzo yoqhagamshelwano lwe-L2 kunye nelinye iziko ledatha, ngoko i-VLAN yayo yondliwa kwiiswitshi ze-VXLAN.
Umthengi C2 iiseva ezibamba kwi I-POD 2 ΠΈ I-POD 3, Umxhasi weVLAN uchazwa kumbala oluhlaza omnyama. Lo mxhasi usebenzisa inkonzo yoqhagamshelwano kunye nenye isikhungo sedatha, kodwa i-L3, ngoko i-VLAN yayo isondliwa kwii-router ze-L3VPN.
Sifuna ii-VLANs zabathengi ukuba baqonde ukuba zeziphi izigaba zomsebenzi wokutshintsha okwenzekayo, apho uphazamiseko lonxibelelwano lwenzeka khona, kunye nokuba lingakanani ixesha. Iprotocol ye-STP ayisetyenziswanga kwesi sikimu, ekubeni ububanzi bomthi kulo mbandela bukhulu, kwaye ukudibanisa kweprotocol kukhula ngokukhawuleza kunye nenani lezixhobo kunye namakhonkco phakathi kwabo.
Zonke izixhobo ezidityaniswe ngamakhonkco aphindwe kabini zenza i-stack, i-MLAG pair okanye i-VCS Ethernet ilaphu. Kwii-router ze-L3VPN, ezo teknoloji azisetyenziswanga, kuba akukho mfuneko yokuphindaphinda kwe-L2; kwanele ukuba banokuqhagamshelwa kwe-L2 omnye komnye ngokutshintshwa kokudibanisa.
Iinketho zokuphumeza
Xa sihlalutya iinketho zeziganeko ezongezelelweyo, siye safumanisa ukuba kukho iindlela ezininzi zokwenza lo msebenzi. Ukususela kwikhefu lehlabathi lonke kwinethiwekhi yendawo yonke, ukuya kwincinci ngokoqobo i-1-2 ikhefu lesibini kwiindawo zenethiwekhi.
Inethiwekhi, yima! Iitshintshi, zibuyisele!
Eyona ndlela ilula, ngokuqinisekileyo, kukubhengeza ikhefu lonxibelelwano lwehlabathi kuzo zonke ii-POD kunye nazo zonke iinkonzo ze-DCI kwaye utshintshe onke amakhonkco ukusuka kwiiswitshi. Π kwiiswitshi N.
Ngaphandle kokuphazamiseka, ixesha esingenakukwazi ukuqikelela ngokuthembekileyo (ewe, siyayazi inani lamakhonkco, kodwa asazi ukuba mangaphi amaxesha into eya kungahambi kakuhle - ukusuka kwintambo yesiqwenga ephukileyo okanye isinxibelelanisi esonakeleyo kwi-port ephosakeleyo okanye i-transceiver. ), asikwazi ukuqikelela kwangaphambili ukuba ubude beentambo ze-patch, i-DAC, i-AOC, idityaniswe kwi-switch endala A, iya kuba yanele ukuba ifikelele kwiiswitshi ezintsha ze-N, nangona zimi ecaleni kwazo, kodwa zincinci ukuya. icala, nokuba ngaba i-transceivers efanayo iya kusebenza / i-DAC / i-AOC ukusuka kwi-Brocade itshintshela kwi-Arista.
Kwaye konke oku phantsi kweemeko zoxinzelelo olunzima oluvela kubathengi kunye nenkxaso yobugcisa ("Natasha, vuka! Natasha, yonke into ayisebenzi apho! UNatasha, sele sibhalele inkxaso yobugcisa, ngokunyanisekileyo! UNatasha, sele belahle yonke into. ! Natasha, bangaphi na esingayi kuyenza? Natasha, iya kusebenza nini?!"). Nangona ikhefu elichazwe kwangaphambili kunye nesaziso kubaxhasi, ukungena kwezicelo ngexesha elinjalo kuqinisekisiwe.
Yeka, 1-2-3-4!
Kuthekani ukuba asibhengezi ikhefu lehlabathi, kodwa kunoko uchungechunge lweziphazamiso ezincinci zonxibelelwano lwe-POD kunye neenkonzo ze-DCI. Ngexesha lekhefu lokuqala, tshintshela kwiiswitshi N kuphela I-POD 1, okwesibini - kwiintsuku ezimbalwa - I-POD 2, emva koko iintsuku ezimbalwa I-POD 3, ngoko I-POD 4β¦[N], emva koko i-VXLAN iyatshintsha kwaye emva koko iirotha ze-L3VPN.
Ngalo mbutho wokutshintsha umsebenzi, sinciphisa ubunzima bomsebenzi wexesha elilodwa kunye nokwandisa ixesha lethu lokusombulula iingxaki ukuba kukho into eyenzekayo ngokukhawuleza. I-POD 1 ihlala iqhagamshelwe kwezinye ii-POD kunye nee-DCIs emva kokutshintsha. Kodwa umsebenzi ngokwawo utsala ixesha elide; ngexesha lomsebenzi kwiziko ledatha, injineli iyadingeka ukuba yenze utshintsho ngokwasemzimbeni, kwaye ngexesha lomsebenzi (kwaye umsebenzi onjalo uyenziwa, njengomthetho, ebusuku, ukusuka kwi-2 ukuya ku-5 am), ubukho benjineli yothungelwano lwe-intanethi iyafuneka kwinqanaba eliphezulu lemfundo. Kodwa ke sifumana ukuphazamiseka okufutshane kunxibelelwano, njengomthetho, umsebenzi unokuqhutywa kwisithuba sesiqingatha seyure kunye nekhefu ukuya kuthi ga kwimizuzu emi-2 (ekuqheliseni, rhoqo imizuzwana engama-20 ukuya kwengama-30 ngokuziphatha okulindelweyo kwesixhobo).
Kumzekelo umxhasi C1 okanye umxhasi C2 kuya kufuneka ulumkise malunga nomsebenzi kunye nokuphazamiseka konxibelelwano ubuncinane kathathu - okokuqala ukwenza umsebenzi kwiPOD enye, apho enye yeeseva zayo ikhona, okwesibini - okwesibini, kunye neyesithathu - xa ukutshintsha izixhobo zeenkonzo ze-DCI.
Ukutshintsha amajelo onxibelelwano adityanisiweyo
Kutheni sithetha ngokuziphatha okulindelekileyo kwezixhobo, kwaye amajelo adityanisiweyo angatshintshwa njani ngelixa unciphisa uphazamiseko lonxibelelwano? Masibe nomfanekiso-ngqondweni walo mfanekiso ulandelayo:
Kwelinye icala lekhonkco kukho iiswitshi zokuhambisa iPOD - D1 ΠΈ D2, benza iperi ye-MLAG kunye (i-stack, i-VCS factory, i-vPC pair), kwelinye icala kukho amakhonkco amabini - Xhumanisa i1 ΠΈ Xhumanisa i2 -ibandakanyiwe kwiperi ye-MLAG yokutshintsha okukudala kokudityaniswa Π. Kwicala lokutshintsha D ujongano oludityanisiweyo olunegama Isitishi sezibuko A, kwicala lokutshintsha kokudibanisa Π -ujongano oludityanisiweyo olunegama Isitishi sezibuko D.
Ujongano oludityanisiweyo lusebenzisa i-LACP ekusebenzeni kwayo, oko kukuthi, iiswitshi kumacala omabini rhoqo zitshintshiselana ngeepakethi ze-LACPDU kuwo omabini amakhonkco ukuqinisekisa ukuba amakhonkco:
- abasebenzi;
- ifakwe kwiperi enye yezixhobo kwicala elikude.
Xa utshintshisa iipakethi, ipakethi ithwala ixabiso inkqubo-id, ebonisa isixhobo apho la makhonkco afakwe khona. Kwiperi ye-MLAG (i-stack, i-factory, njl.), ixabiso le-id yesistim yezixhobo ezenza ujongano oludityanisiweyo luyafana. Tshintsha D1 ithumela ku Xhumanisa i1 intsingiselo inkqubo-id D, kwaye utshintshe D2 ithumela ku Xhumanisa i2 intsingiselo inkqubo-id D.
Iiswitshi A1 ΠΈ A2 hlalutya iipakethi ze-LACPDU ezifunyenwe ngaphezulu kojongano lwe-Po D kwaye khangela ukuba inkqubo-id kuzo iyahambelana. Ukuba inkqubo-id efunyenwe ngekhonkco elithile iyahluka ngesiquphe ukusuka kwixabiso lokusebenza langoku, ngoko eli khonkco liyasuswa kujongano oludityanisiweyo de imeko ilungiswe. Ngoku kwicala lethu lokutshintsha D ixabiso langoku le-id yenkqubo evela kwiqabane LACP - A, kwaye kwicala lokutshintsha Π - ixabiso le-id yenkqubo yangoku kwiqabane le-LACP - D.
Ukuba sifuna ukutshintsha ujongano oludityanisiweyo, sinokuyenza ngeendlela ezimbini ezahlukeneyo:
Indlela 1 - Elula
Khubaza amakhonkco omabini ukusuka kutshitshi A. Kule meko, itshaneli edibeneyo ayisebenzi.
Qhagamshela amakhonkco omabini enye kwenye kwizitshixo N, emva koko iiparamitha zokusebenza ze-LACP ziya kuxoxwa kwakhona kwaye i-interface iya kwenziwa Po D kwiiswitshi N kunye nokuhanjiswa kwamaxabiso kumakhonkco inkqubo-id N.
Indlela yesi-2 - Nciphisa ukuphazamiseka
Nqamula uQhagamshelwano lwesi-2 ekutshintsheni i-A2. Ngexesha elifanayo, i-traffic phakathi Π ΠΈ D izakuqhubeka nokuhanjiswa ngokulula kwelinye lamakhonkco, eliya kuhlala liyinxalenye yojongano oludityanisiweyo.
Qhagamshela iLinki yesi-2 ukuze utshintshe i-N2. Kwiswitshi N ujongano oludityanisiweyo sele luqwalaselwe Nge-DN, kwaye utshintshe N2 izakuqala ukuthumela kwi-LACPDU inkqubo-id N. Kweli nqanaba sinokujonga ukuba iswitshi N2 isebenza ngokuchanekileyo kunye ne-transceiver esetyenzisiweyo Xhumanisa i2, ukuba izibuko lodibaniso lingenile kwimeko Up, kwaye akukho ziphoso zenzeka kwizibuko loqhagamshelwano xa uthumela ii-LACPDU.
Kodwa into yokuba utshintsho D2 kujongano oludityanisiweyo Po A ukusuka ecaleni Ikhonkco 2 ifumana ixabiso le-id yenkqubo ye-N eyahlukileyo kwindlela yokusebenza yangoku-ixabiso le-id A, ayivumeli utshintsho D ukwazisa Xhumanisa i2 inxalenye yojongano oludityanisiweyo Po A. Tshintsha N ayikwazi ukungena Xhumanisa i2 ukusebenza, kuba ayifumani siqinisekiso sokusebenza kwiqabane le-LACP lokutshintsha D2. Iziphumo zetrafikhi zi Xhumanisa i2 engagqibi.
Kwaye ngoku sicima i-Link 1 kwi-switch A1, ngaloo ndlela kuvinjwa iiswitshi Π ΠΈ D ujongano oludityanisiweyo olusebenzayo. Ngoko kwicala lokutshintsha D ixabiso langoku le-id yendlela yokusebenza yojongano luyanyamalala Po A.
Oku kuvumela utshintsho D ΠΈ N vuma inkqubo yotshintshiselwano-id AN kujongano Po A ΠΈ Nge-DN, ukuze itrafikhi iqale ukuhanjiswa kunye nekhonkco Xhumanisa i2. Ikhefu kule meko, ekusebenzeni, ukuya kwi-2 imizuzwana.
Kwaye ngoku sinokutshintsha ngokulula ikhonkco loku-1 ukutshintshela i-N1, ukubuyisela umthamo kunye nenqanaba lokudityaniswa kwe-interface Po A ΠΈ Nge-DN. Ukusukela xa eli khonkco liqhagamshelwe, ixabiso langoku le-id yenkqubo ayitshintshi macala, akukho kuphazamiseka.
Iikhonkco ezongezelelweyo
Kodwa utshintsho lunokwenziwa ngaphandle kobukho bobunjineli ngexesha lokutshintsha. Ukwenza oku, kuya kufuneka sibeke amakhonkco ongezelelweyo phakathi kokutshintshwa kokusabalalisa kwangaphambili D kunye neeswitshi ezintsha zokuhlanganisa N.
Sibeka amakhonkco amatsha phakathi kokutshintsha okudityanisiweyo N kunye nokuhanjiswa kokutshintsha kuzo zonke iiPOD. Oku kufuna uku-odola kunye nokubeka iintambo ezongezelelweyo, kunye nokufakela ii-transceivers ezongezelelweyo njengoko kunjalo N, nangaphakathi D. Singakwenza oku kuba kwiiswitshi zethu D I-POD nganye inamazibuko asimahla (okanye siwakhulule kwangaphambili). Ngenxa yoko, i-POD nganye idityaniswe ngokwasemzimbeni ngamakhonkco amabini kwiiswitshi ezindala A kunye nokutshintsha okutsha okungu-N.
Kwiswitshi D ujongano oludityanisiweyo lwenziwe - Po A ngamakhonkco Xhumanisa i1 ΠΈ Xhumanisa i2kwaye Po N - kunye namakhonkco Ikhonkco N1 ΠΈ Ikhonkco N2. Ngeli nqanaba, sijonga uxhulumaniso oluchanekileyo lwe-interfaces kunye neekhonkco, amanqanaba ezibonakaliso ze-optical kuzo zombini iziphelo zekhonkco (ngolwazi lwe-DDM oluvela kwiiswitshi), sinokujonga nokusebenza kwekhonkco phantsi komthwalo okanye ukubeka iliso kumazwe imiqondiso yokubona kunye nobushushu be-transceiver iintsuku ezimbalwa.
Itrafikhi isathunyelwa ngojongano Po A, kunye nojongano Po N iindleko akukho traffic. Iisetingi kujongano zizinto ezinje:
Interface Port-channel A
Switchport mode trunk
Switchport allowed vlan C1, C2
Interface Port-channel N
Switchport mode trunk
Switchport allowed vlan noneUkutshintsha kwe-D, njengomthetho, utshintsho olusekwe kwiseshoni yenkxaso, tshintsha iimodeli ezinolu setyenziso. Ke sinokutshintsha useto lwe-Po A kunye ne-Po N yojongano kwinqanaba elinye:
Configure session
Interface Port-channel A
Switchport allowed vlan none
Interface Port-channel N
Switchport allowed vlan C1, C2
CommitEmva koko utshintsho lokucwangciswa luya kwenzeka ngokukhawuleza ngokwaneleyo, kwaye ikhefu, ekusebenzeni, lingabi ngaphezu kwemizuzwana emi-5.
Le ndlela ivumela ukuba sigqibe wonke umsebenzi wokulungiselela kwangaphambili, senze zonke iitshekhi eziyimfuneko, silungelelanise umsebenzi kunye nabathathi-nxaxheba kwinkqubo, ukuqikelela ngokweenkcukacha izenzo zokuvelisa umsebenzi, ngaphandle kweenqwelo-moya zokudala xa "yonke into ayihambanga kakuhle. ,β kwaye ube nesicwangciso sokubuyela kulungiselelo lwangaphambili. Umsebenzi ngokwesi sicwangciso wenziwa yinjineli yenethiwekhi ngaphandle kobukho benjineli yedatha kwiziko eliqhuba ngokwasemzimbeni ukutshintshwa.
Yintoni ebalulekileyo ngale ndlela yokutshintsha kukuba zonke iikhonkco ezintsha sele zibekwe esweni kwangaphambili. Iimpazamo, ukufakwa kweekhonkco kwiyunithi, ukulayishwa kweekhonkco - lonke ulwazi oluyimfuneko sele lusele lukwinkqubo yokubeka iliso, kwaye oku sele kufakwe kwiimephu.
D-Day
IPOD
Sikhethe eyona ndlela incinci yokutshintsha ibuhlungu kubaxumi kunye neyona ndlela incinci yokutyekela "kwinto engahambanga kakuhle" kunye neekhonkco ezongezelelweyo. Ke sitshintshe zonke ii-POD kutshintsho olutsha lokudibanisa ngobusuku nje obubini.
Kodwa okuseleyo kukutshintsha izixhobo ezibonelela ngeenkonzo zeDCI.
L2
Kwimeko yezixhobo ezibonelela nge-L2 uxhumano, asikwazanga ukwenza umsebenzi ofanayo kunye neekhonkco ezongezelelweyo. Kukho izizathu ezibini zoku:
- Ukunqongophala kwamazibuko asimahla kwisantya esifunekayo kwiiswitshi zeVXLAN.
- Ukunqongophala koqwalaselo lweseshini yokutshintsha ukusebenza kwiiswitshi zeVXLAN.
Asizange sitshintshe amakhonkco "enye ngexesha" kunye nekhefu kuphela ngelixa sivumelana ngesibini se-id yenkqubo entsha, ekubeni sasingenalo ukuzithemba kwe-100% ukuba inkqubo iya kwenzeka ngokuchanekileyo, kwaye uvavanyo kwibhubhoratri lubonise ukuba imeko ukuba "into ayihambanga kakuhle," sisafumana ukuphazamiseka koxhulumaniso, kwaye eyona nto imbi kakhulu kungekhona nje kubathengi abanonxibelelwano lwe-L2 kunye namanye amaziko edatha, kodwa ngokubanzi kubo bonke abathengi beli ziko ledatha.
Senze umsebenzi wepropaganda ngaphambi kwexesha kwinguqu evela kumajelo e-L2, ngoko ke inani labathengi abachatshazelwa ngumsebenzi kwi-VXLAN switches lalisele liphindwe kaninzi ngaphantsi konyaka odlulileyo. Ngenxa yoko, siye sagqiba ukuphazamisa unxibelelwano ngenkonzo yoqhagamshelwano lwe-L2, ngaphandle kokuba sigcina ukusebenza okuqhelekileyo kweenkonzo zenethiwekhi yendawo kwindawo enye yedatha. Ukongeza, i-SLA yale nkonzo ibonelela ngamathuba okwenza umsebenzi ocwangcisiweyo kunye neziphazamiso.
L3
Kutheni sicebise ukuba wonke umntu atshintshele kwi-L3VPN xa eququzelela iinkonzo ze-DCI? Esinye sezizathu kukukwazi ukwenza umsebenzi kwenye yee-routers ezibonelela ngale nkonzo, ukunciphisa nje inqanaba lokuphindaphinda ukuya kwi-N + 0, ngaphandle kokuphazamisa unxibelelwano.
Makhe siqwalasele ngakumbi inkqubo yonikezelo lweenkonzo. Kule nkonzo, icandelo le-L2 lisuka kwiiseva zabathengi kuphela ukuya kwi-L3VPN Selectel routers. Uthungelwano lomxhasi luphelisiwe kwiirotha.
Umncedisi womxhasi ngamnye, umz. S2 ΠΈ S3 kulo mzobo ungentla, banedilesi zabo ze-IP zabucala - 10.0.0.2/24 kwiseva S2 ΠΈ 10.0.0.3/24 kwiseva S3. Iidilesi 10.0.0.252/24 ΠΈ 10.0.0.253/24 yabelwe nguSelectel kwiirotha I-L3VPN-1 ΠΈ I-L3VPN-2, ngokulandelelanayo. Idilesi ye-IP 10.0.0.254/24 yidilesi ye-VRRP VIP kwiirotha ze-Selectel.
Unokufunda ngakumbi malunga nenkonzo ye-L3VPN kwiblogi yethu.
Ngaphambi kokutshintsha, yonke into yayijongeka njengakumzobo:
Iirotha ezimbini I-L3VPN-1 ΠΈ I-L3VPN-2 zaziqhagamshelwe kwisitshixo esidala sokudibanisa Π. Inkosi ye-VRRP idilesi ye-VIP 10.0.0.254 yi-router I-L3VPN-1. Inokubaluleka okuphezulu kule dilesi kune-router 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;
}
}
}
}Umncedisi we-S2 usebenzisa isango 10.0.0.254 ukunxibelelana nabancedisi kwezinye iindawo. Ngaloo ndlela, ukukhupha i-L3VPN-2 i-router kwinethiwekhi (ngokuqinisekileyo, ukuba ikhutshwe kuqala kwi-domain ye-MPLS) ayichaphazeli uxhulumaniso lweeseva zomthengi. Ngeli nqanaba, inqanaba lokuphindaphinda kwesekethe liyancipha nje.
Emva koku sinokuphinda siqhagamshele i-router ngokukhuselekileyo I-L3VPN-2 kwipere yokutshintsha N. Lay links, utshintsho transceivers. I-interfaces enengqiqo ye-router, apho ukusebenza kweenkonzo zomxhasi kuxhomekeke khona, zivaliwe de kube kuqinisekiswe ukuba yonke into isebenza njengoko kufanelekile.
Emva kokutshekisha amakhonkco, i-transceivers, amanqanaba omqondiso, kunye namanqanaba eempazamo kwi-interfaces, i-router ifakwe ekusebenzeni, kodwa sele ixhunyiwe kwibini entsha yokutshintsha.
Emva koko, sinciphisa i-VRRP ephambili ye-L3VPN-1 i-router, kwaye idilesi ye-VIP 10.0.0.254 ihanjiswe kwi-router ye-L3VPN-2. Le misebenzi yenziwa ngaphandle kokuphazamiseka konxibelelwano.
Ukutshintshela idilesi ye-VIP 10.0.0.254 kwi-router I-L3VPN-2 ikuvumela ukuba ukhubaze i-router I-L3VPN-1 ngaphandle kokuphazamiseka konxibelelwano lomxhasi kwaye uqhagamshele kwiperi entsha yokutshintsha kokudibanisa N.
Ingaba okanye ungayibuyiseli i-VRRP VIP kwi-L3VPN-1 i-router ngomnye umbuzo, kwaye nokuba ibuyiswe, yenziwa ngaphandle kokuphazamisa uxhumano.
Iyonke
Emva kwawo onke la manyathelo, sithathe indawo yokutshintsha kokudibanisa kwelinye lamaziko ethu edatha, ngelixa sinciphisa ukuphazamiseka kubathengi bethu.
Okuseleyo kukudilizwa. Ukuchithwa kwezinto ezitshintshileyo ezindala, ukuchithwa kwamakhonkco amadala phakathi kokutshintsha i-A kunye no-D, ukuchithwa kwee-transceivers ezivela kula makhonkco, ukulungiswa kokubeka iliso, ukulungiswa kwemizobo yenethiwekhi kumaxwebhu kunye nokubeka iliso.
Singasebenzisa utshintsho, i-transceivers, i-patch cords, i-AOC, i-DAC ekhohlo emva kokutshintsha kwezinye iiprojekthi okanye enye into efanayo.
"Natasha, sitshintshe yonke into!"
