🥇 Dab neeg ntawm ib qho hloov pauv

Nyob rau hauv peb lub zos network aggregation peb muaj rau khub ntawm Arista DCS-7050CX3-32S keyboards thiab ib khub ntawm Brocade VDX 6940-36Q keyboards. Nws tsis yog tias peb tau ntxhov siab dhau los ntawm Brocade keyboards hauv lub network no, lawv ua haujlwm thiab ua lawv txoj haujlwm, tab sis peb tab tom npaj tag nrho automation ntawm qee qhov kev ua, thiab peb tsis muaj peev xwm ntawm cov keyboards no. Kuv kuj xav hloov los ntawm 40GE interfaces mus rau qhov muaj peev xwm ntawm kev siv 100GE txhawm rau ua kom muaj kev cia siab rau 2-3 xyoos tom ntej. Yog li peb txiav txim siab hloov Brocade rau Arista.

Cov keyboards no yog LAN aggregation keyboards rau txhua qhov chaw cov ntaub ntawv. Distribution switches (theem thib ob ntawm kev sib sau ua ke) tau txuas ncaj qha rau lawv, uas twb tau sib sau ua ke Top-of-Rack hauv zos network keyboards hauv racks nrog servers.

Txhua tus neeg rau zaub mov txuas nrog ib lossis ob qhov kev nkag mus. Cov keyboards nkag mus tau txuas nrog ob lub hloov pauv hloov pauv (ob lub hloov pauv hloov pauv thiab ob lub cev sib txuas los ntawm kev nkag mus rau cov hloov pauv sib txawv yog siv rau kev rov ua dua).

Txhua tus neeg rau zaub mov tuaj yeem siv los ntawm nws tus kheej cov neeg siv khoom, yog li tus neeg siv khoom tau faib VLAN cais. Tib VLAN ces sau npe rau ntawm lwm tus neeg rau zaub mov ntawm tus neeg siv khoom no hauv txhua qhov khib. Cov ntaub ntawv chaw muaj ntau yam xws li kab (PODs), txhua kab ntawm racks muaj nws tus kheej hloov pauv. Tom qab ntawd cov kev faib hluav taws xob no txuas nrog cov hloov pauv sib sau ua ke.

Cov neeg siv khoom tuaj yeem xaj tus neeg rau zaub mov hauv txhua kab; nws tsis tuaj yeem kwv yees ua ntej tias tus neeg rau zaub mov yuav raug faib lossis nruab rau hauv ib kab tshwj xeeb hauv cov khib nyiab tshwj xeeb, uas yog vim li cas muaj txog 2500 VLANs ntawm kev sib sau ua ke hauv txhua qhov chaw khaws ntaub ntawv.

Cov cuab yeej siv rau DCI (Data-Center Interconnect) yog txuas nrog cov kev sib txuas sib txuas. Nws tuaj yeem npaj rau kev sib txuas L2 (ib khub ntawm cov keyboards tsim VXLAN qhov rau lwm qhov chaw cov ntaub ntawv) lossis rau L3 txuas (ob lub MPLS routers).

Raws li kuv twb tau sau lawm, txhawm rau sib koom ua ke cov txheej txheem ntawm automating qhov kev teeb tsa ntawm cov kev pabcuam ntawm cov khoom siv hauv ib lub chaw khaws ntaub ntawv, nws yog qhov tsim nyog los hloov cov hloov pauv hauv nruab nrab. Peb tau teeb tsa cov hloov tshiab ntawm ib sab ntawm cov uas twb muaj lawm, muab tso ua ke rau hauv ib khub MLAG thiab pib npaj ua haujlwm. Lawv tau txuas nrog tam sim ntawd rau cov kev sib sau ua ke uas twb muaj lawm, kom lawv muaj qhov sib xws L2 sau thoob plaws txhua tus neeg siv VLANs.

Cov ntsiab lus ntawm Circuit Court

Rau qhov tshwj xeeb, cia peb lub npe rau cov keyboards qub sib sau ua ke A1 и A2, nov - N1 и N2. Cia peb xav txog qhov ntawd hauv PAB 1 и PAB 4 servers ntawm ib tus neeg siv khoom yog tuav C1, Tus neeg siv VLAN tau qhia hauv xiav. Tus neeg siv khoom no siv L2 kev pabcuam txuas nrog lwm qhov chaw khaws ntaub ntawv, yog li nws cov VLAN tau pub rau ib khub ntawm VXLAN keyboards.

Neeg C2 hosts servers hauv PAB 2 и PAB 3, Tus neeg siv khoom VLAN yog qhia hauv ntsuab tsaus. Cov neeg siv khoom no kuj siv cov kev pabcuam txuas nrog lwm lub chaw cov ntaub ntawv, tab sis L3, yog li nws cov VLAN tau pub rau ib khub ntawm L3VPN routers.

Peb xav tau cov neeg siv VLANs kom nkag siab txog theem twg ntawm kev hloov pauv ua haujlwm dab tsi tshwm sim, qhov twg kev sib txuas lus cuam tshuam tshwm sim, thiab nws lub sijhawm ntev npaum li cas. STP raws tu qauv tsis siv nyob rau hauv cov tswv yim no, vim hais tias qhov dav ntawm tsob ntoo rau nws nyob rau hauv cov ntaub ntawv no yog loj, thiab convergence ntawm tus txheej txheem loj hlob exponentially nrog cov xov tooj ntawm cov khoom siv thiab kev sib txuas ntawm lawv.

Tag nrho cov khoom siv txuas nrog los ntawm ob qhov sib txuas tsim ib pawg, MLAG khub lossis VCS Ethernet ntaub. Rau ib khub ntawm L3VPN routers, cov thev naus laus zis no tsis siv, vim tsis tas yuav muaj L2 redundancy; nws txaus tias lawv muaj L2 txuas rau ib leeg los ntawm kev sib sau ua ke.

Cov kev xaiv ua

Thaum txheeb xyuas cov kev xaiv rau cov xwm txheej ntxiv, peb pom tau tias muaj ntau txoj hauv kev los ua txoj haujlwm no. Los ntawm lub ntiaj teb so ntawm tag nrho cov hauv zos network, mus rau me me 1-2 thib ob so nyob rau hauv ib feem ntawm lub network.

Network, nres! Hloov pauv, hloov lawv!

Txoj kev yooj yim tshaj plaws yog, tau kawg, tshaj tawm kev sib txuas lus thoob ntiaj teb rau tag nrho PODs thiab tag nrho cov kev pabcuam DCI thiab hloov txhua qhov txuas los ntawm cov keyboards. А mus hloov N.

Sib nrug los ntawm kev cuam tshuam, lub sijhawm uas peb tsis tuaj yeem ntseeg tau kwv yees (yog, peb paub cov lej txuas, tab sis peb tsis paub pes tsawg zaus ib yam dab tsi yuav mus tsis ncaj ncees lawm - los ntawm cov kab tawg tawg lossis cov khoom sib txuas puas mus rau qhov chaw nres nkoj tsis raug lossis transceiver. ), peb tseem tsis tuaj yeem kwv yees ua ntej seb qhov ntev ntawm cov hlua khi, DAC, AOC, txuas nrog lub qub keyboards A, yuav txaus kom ncav cuag lawv mus rau qhov hloov tshiab N, txawm tias sawv ntawm lawv ib sab, tab sis tseem me ntsis rau. sab, thiab seb tib lub transceivers yuav ua haujlwm / DAC / AOC los ntawm Brocade keyboards rau Arista keyboards.

Thiab tag nrho cov no nyob rau hauv tej yam kev mob hnyav heev los ntawm cov neeg muas zaub thiab kev txhawb nqa ("Natasha, sawv! Natasha, txhua yam tsis ua hauj lwm nyob rau ntawd! Natasha, peb twb tau sau ntawv mus rau technical support, ncaj ncees! Natasha, lawv twb tau poob txhua yam. Natasha, muaj pes tsawg tus ntxiv peb yuav tsis ua haujlwm? Natasha, thaum twg nws yuav ua haujlwm?!"). Txawm hais tias tau tshaj tawm ua ntej kev so thiab kev ceeb toom rau cov neeg siv khoom, qhov kev thov nkag ntawm lub sijhawm no tau lees paub.

Nres, 1-2-3-4!

Yuav ua li cas yog tias peb tsis tshaj tawm kev so thoob ntiaj teb, tab sis qhov kev sib txuas lus me me cuam tshuam rau POD thiab DCI cov kev pabcuam. Thaum thawj zaug so, hloov mus rau cov keyboards N tsuas PAB 1, nyob rau hauv lub thib ob - nyob rau hauv ob peb hnub - PAB 2, ces ob peb hnub ntxiv PAB 3, Ntxiv POD 4…[N], ces VXLAN keyboards thiab ces L3VPN routers.

Nrog rau lub koom haum no ntawm kev hloov ua haujlwm, peb txo qis qhov nyuaj ntawm kev ua haujlwm ib zaug thiab ua kom peb lub sijhawm los daws cov teeb meem yog tias muaj qee yam tsis ncaj ncees lawm. POD 1 tseem txuas nrog lwm PODs thiab DCIs tom qab hloov. Tab sis kev ua haujlwm nws tus kheej rub ntev ntev; thaum lub sijhawm ua haujlwm no hauv cov ntaub ntawv chaw, tus kws tshaj lij yuav tsum ua lub cev hloov pauv, thiab thaum ua haujlwm (thiab cov haujlwm no tau ua, raws li txoj cai, thaum hmo ntuj, los ntawm 2. mus txog 5 teev sawv ntxov), lub xub ntiag ntawm tus kws tshaj lij hauv online network yog xav tau ntawm kev tsim nyog qib siab. Tab sis tom qab ntawd peb tau txais kev cuam tshuam kev sib txuas lus luv luv; raws li txoj cai, kev ua haujlwm tuaj yeem ua tiav hauv ib nrab ib teev nrog kev so txog li 2 feeb (hauv kev xyaum, feem ntau 20-30 vib nas this nrog cov kev xav tau ntawm cov khoom siv).

Hauv qhov piv txwv tus neeg siv khoom C1 los yog tus neeg siv khoom C2 koj yuav tsum ceeb toom txog kev ua haujlwm nrog kev sib txuas lus cuam tshuam tsawg kawg peb zaug - thawj zaug ua haujlwm ntawm ib qho POD, nyob rau hauv uas ib qho ntawm nws cov servers nyob, lub sijhawm thib ob - thib ob, thiab thib peb - thaum Hloov khoom siv rau DCI cov kev pabcuam.

Hloov cov kev sib txuas lus sib txuas

Vim li cas peb tham txog tus cwj pwm xav tau ntawm cov cuab yeej siv, thiab cov kev sib sau ua ke tuaj yeem hloov pauv li cas thaum txo kev cuam tshuam kev sib txuas lus? Cia peb xav txog cov duab hauv qab no:

Ntawm ib sab ntawm qhov txuas muaj POD faib hloov pauv - D1 и D2, lawv tsim MLAG khub nrog ib leeg (pawg, VCS Hoobkas, vPC khub), ntawm qhov tod tes, muaj ob qhov txuas - Txuas 1 и Txuas 2 - suav nrog MLAG khub ntawm kev sib sau ua ke qub А. Nyob rau sab hloov D ib tug aggregated interface nrog lub npe Chaw nres nkoj-channel A, nyob rau sab ntawm aggregation keyboards А - aggregated interface nrog lub npe Chaw nres nkoj-channel D.

Aggregated interfaces siv LACP hauv lawv txoj haujlwm, uas yog, hloov ntawm ob sab tsis tu ncua pauv LACPDU pob ntawv ntawm ob qhov txuas kom paub tseeb tias cov kev sib txuas:

cov neeg ua haujlwm;
suav nrog hauv ib khub ntawm cov khoom siv ntawm sab nraud.

Thaum sib pauv pob ntawv, pob ntawv nqa tus nqi system-id, qhia cov cuab yeej uas cov kev txuas no suav nrog. Rau ib khub MLAG (pawg, Hoobkas, thiab lwm yam), tus nqi system-id rau cov khoom siv uas tsim cov kev sib txuas sib txuas yog tib yam. Hloov D1 xa mus Txuas 1 lub ntsiab lus system-id D, thiab hloov D2 xa mus Txuas 2 lub ntsiab lus system-id D.

Hloov A1 и A2 txheeb xyuas LACPDU pob ntawv tau txais ntau dua ib qho Po D interface thiab xyuas seb qhov system-id hauv lawv qhov sib tw. Yog tias qhov system-id tau txais los ntawm qee qhov txuas tam sim ntawd txawv los ntawm tus nqi khiav haujlwm tam sim no, ces qhov txuas no raug tshem tawm ntawm qhov sib xyaw ua ke kom txog thaum qhov xwm txheej raug kho. Tam sim no ntawm peb sab hloov D tam sim no system-id tus nqi los ntawm LACP tus khub - A, thiab nyob rau sab hloov А - tam sim no qhov system-id tus nqi los ntawm LACP tus khub - D.

Yog tias peb xav hloov qhov sib xyaw ua ke, peb tuaj yeem ua nws hauv ob txoj kev sib txawv:

Txoj Kev 1 - Yooj yim
Disable ob qhov txuas los ntawm cov keyboards A. Hauv qhov no, cov channel sib sau ua ke tsis ua haujlwm.

Txuas ob qhov txuas ib los ntawm ib qho mus rau cov keyboards N, ces LACP kev khiav hauj lwm tsis yuav tsum tau sib tham dua thiab lub interface yuav raug tsim PoD ntawm keyboards N thiab kis tau tus nqi ntawm cov kev sib txuas system-id N.

Txoj Kev 2 - Txo kev cuam tshuam tsawg kawg nkaus
Disconnect Txuas 2 los ntawm kev hloov A2. Nyob rau tib lub sij hawm, tsheb khiav ntawm А и D yuav txuas ntxiv kis tau yooj yim tshaj ib qho ntawm cov kev sib txuas, uas yuav nyob twj ywm ib feem ntawm qhov sib xyaw ua ke.

Txuas Txuas 2 los hloov N2. Ntawm qhov hloov N lub aggregated interface twb configured Po DN, thiab hloov N2 yuav pib kis mus rau LACPDU system-id N. Nyob rau theem no peb tuaj yeem kuaj xyuas tias qhov hloov pauv N2 ua haujlwm kom raug nrog lub transceiver siv rau Txuas 2, tias qhov chaw nres nkoj txuas tau nkag mus rau hauv lub xeev Up, thiab tsis muaj qhov yuam kev tshwm sim ntawm qhov chaw nres nkoj txuas thaum xa LACPDUs.

Tab sis qhov tseeb tias qhov hloov D2 rau aggregated interface Po A los ntawm sab Txuas 2 tau txais qhov system-id N tus nqi sib txawv ntawm qhov kev ua haujlwm tam sim no-id A tus nqi, tsis pub keyboards D kom paub Txuas 2 ib feem ntawm lub aggregated interface Po A. Hloov N nkag tsis tau Txuas 2 ua haujlwm, vim nws tsis tau txais kev pom zoo ntawm kev ua haujlwm los ntawm LACP tus khub ntawm qhov hloov D2. Qhov tshwm sim kev khiav tsheb yog Txuas 2 tsis tau dhau.

Thiab tam sim no peb kaw Link 1 los ntawm kev hloov A1, yog li depriving cov keyboards А и D ua hauj lwm aggregate interface. Yog li ntawm qhov hloov sab D tam sim no ua hauj lwm system-id nqi rau lub interface ploj Po A.

Qhov no tso cai rau cov keyboards D и N pom zoo sib pauv system-id AN ntawm interfaces Po A и Po DN, yog li ntawd cov tsheb thauj neeg pib kis tau raws li qhov txuas Txuas 2. Kev so hauv qhov no yog, hauv kev xyaum, mus txog 2 vib nas this.

Thiab tam sim no peb tuaj yeem hloov qhov txuas 1 tau yooj yim hloov N1, restores lub peev xwm thiab theem ntawm interface redundancy Po A и Po DN. Txij li thaum qhov txuas no txuas nrog, tus nqi tam sim no-id tsis hloov ntawm ob sab, tsis muaj kev cuam tshuam.

Txuas ntxiv

Tab sis qhov hloov pauv tuaj yeem ua tau yam tsis muaj tus kws tshaj lij thaum lub sijhawm hloov pauv. Txhawm rau ua qhov no, peb yuav tsum tau tso cov kev sib txuas ntxiv ntawm cov hloov pauv ua ntej D thiab tshiab aggregation keyboards N.

Peb tab tom tso cov kev sib txuas tshiab ntawm kev sib sau ua ke N thiab faib cov hloov pauv rau txhua PODs. Qhov no yuav tsum tau xaj thiab tso cov hlua txuas ntxiv, thiab txhim kho cov transceivers ntxiv raws li hauv N, thiab nyob rau hauv D. Peb tuaj yeem ua qhov no vim tias hauv peb cov keyboards D Txhua POD muaj cov chaw nres nkoj dawb (lossis peb ua ntej pub dawb). Raws li qhov tshwm sim, txhua POD yog lub cev txuas los ntawm ob qhov txuas mus rau cov keyboards qub A thiab mus rau qhov hloov tshiab N.

Ntawm qhov hloov D ob qhov sib xyaw ua ke interfaces tau tsim - Po A nrog kev sib txuas Txuas 1 и Txuas 2thiab Po N - nrog kev sib txuas Link N1 и Link N2. Nyob rau theem no, peb txheeb xyuas qhov tseeb kev sib txuas ntawm kev sib txuas thiab kev sib txuas, theem ntawm cov teeb liab kho qhov muag ntawm ob qhov kawg ntawm kev sib txuas (ntawm DDM cov ntaub ntawv los ntawm cov keyboards), peb tuaj yeem tshawb xyuas qhov kev ua tau zoo ntawm qhov txuas hauv qab load lossis saib xyuas cov xeev ntawm optical signals thiab transceiver kub rau ob peb hnub.

Kev khiav tsheb tseem raug xa mus los ntawm lub interface Po A, thiab lub interface Po N tsis muaj nqi tsheb. Cov kev teeb tsa ntawm lub interfaces yog qee yam zoo li no:

Interface Port-channel A
Switchport mode trunk
Switchport allowed vlan C1, C2

Interface Port-channel N
Switchport mode trunk
Switchport allowed vlan none

D keyboards, raws li txoj cai, kev txhawb nqa kev kho dua tshiab; hloov cov qauv uas muaj cov haujlwm no tau siv. Yog li peb tuaj yeem hloov qhov chaw ntawm Po A thiab Po N interfaces hauv ib kauj ruam:

Configure session
Interface Port-channel A
Switchport allowed vlan none
Interface Port-channel N
Switchport allowed vlan C1, C2
Commit

Tom qab ntawd qhov kev hloov pauv yuav tshwm sim sai txaus, thiab kev so yuav, hauv kev xyaum, tsis pub dhau 5 vib nas this.

Txoj kev no tso cai rau peb ua kom tiav tag nrho cov kev npaj ua ntej, ua tiav tag nrho cov kev kuaj xyuas tsim nyog, sib koom ua haujlwm nrog cov neeg koom nrog hauv cov txheej txheem, kwv yees kom ntxaws txog kev ua haujlwm rau kev tsim khoom, tsis muaj kev sib tw ntawm kev muaj tswv yim thaum "txhua yam yuam kev. ,” thiab muaj nyob ntawm tes ib txoj kev npaj rau rov qab mus rau qhov kev teeb tsa yav dhau los. Ua hauj lwm raws li txoj kev npaj no yog ua los ntawm ib tug network engineer yam tsis muaj ib tug data center engineer ntawm qhov chaw uas lub cev nqa tawm lub switching.

Dab tsi tseem ceeb nrog txoj kev hloov pauv no yog tias txhua qhov txuas tshiab twb tau saib xyuas ua ntej. Kev ua yuam kev, suav nrog kev sib txuas hauv chav tsev, kev thauj khoom ntawm kev sib txuas - tag nrho cov ntaub ntawv tsim nyog yog twb nyob rau hauv kev saib xyuas, thiab qhov no twb tau kos rau hauv daim ntawv qhia.

D-Day

POD

Peb tau xaiv txoj kev hloov pauv uas mob tsawg tshaj plaws rau cov neeg siv khoom thiab tsawg tshaj plaws rau "ib yam dab tsi mus tsis ncaj ncees lawm" cov xwm txheej nrog cov txuas ntxiv. Yog li peb hloov tag nrho cov PODs mus rau cov hloov tshiab sib sau ua ke hauv ob peb hmo.

Tab sis txhua yam uas tseem tshuav yog hloov cov cuab yeej uas muab kev pabcuam DCI.

L2

Nyob rau hauv rooj plaub ntawm cov cuab yeej muab L2 kev sib txuas, peb tsis tuaj yeem ua haujlwm zoo sib xws nrog cov kev sib txuas ntxiv. Muaj tsawg kawg yog ob qho laj thawj rau qhov no:

Tsis muaj cov chaw nres nkoj dawb ntawm qhov xav tau ceev ntawm VXLAN keyboards.
Tsis muaj kev sib kho configuration hloov functionality ntawm VXLAN keyboards.

Peb tsis tau hloov cov kev sib txuas "ib zaug ntawm ib lub sijhawm" nrog kev so tsuas yog thaum pom zoo rau tus tshiab system-id khub, txij li peb tsis muaj 100% kev ntseeg siab tias cov txheej txheem yuav mus kom raug, thiab kev sim hauv chav kuaj pom tias hauv rooj plaub yog "ib yam dab tsi mus tsis ncaj ncees lawm," peb tseem tau txais kev cuam tshuam kev sib txuas, thiab qhov phem tshaj plaws tsis yog rau cov neeg siv khoom uas muaj L2 txuas nrog lwm cov chaw khaws ntaub ntawv, tab sis feem ntau rau txhua tus neeg siv ntawm lub chaw cov ntaub ntawv no.

Peb tau ua haujlwm tshaj tawm ua ntej ntawm kev hloov pauv ntawm L2 raws, yog li tus naj npawb ntawm cov neeg siv khoom cuam tshuam los ntawm kev ua haujlwm ntawm VXLAN keyboards twb ob peb zaug tsawg dua ib xyoos dhau los. Raws li qhov tshwm sim, peb tau txiav txim siab cuam tshuam kev sib txuas lus los ntawm kev pabcuam L2 kev sib txuas, yog tias peb tswj hwm kev ua haujlwm ib txwm muaj ntawm cov kev pabcuam hauv zos hauv ib lub chaw pabcuam. Tsis tas li ntawd, SLA rau qhov kev pabcuam no muab kev muaj peev xwm ua haujlwm tau teem sijhawm nrog kev cuam tshuam.

L3

Vim li cas peb thiaj xav kom txhua tus hloov mus rau L3VPN thaum npaj cov kev pabcuam DCI? Ib qho ntawm cov laj thawj yog lub peev xwm ua haujlwm ntawm ib qho ntawm cov routers uas muab cov kev pabcuam no, tsuas yog txo qis qis dua mus rau N + 0, tsis muaj kev cuam tshuam kev sib txuas lus.

Cia peb saib ze dua ntawm cov txheej txheem xa khoom. Hauv qhov kev pabcuam no, L2 ntu mus los ntawm cov neeg siv khoom siv tsuas yog rau L3VPN Selectel routers. Cov neeg siv khoom network raug txiav tawm ntawm routers.

Txhua tus neeg siv khoom server, e.g. S2 и S3 hauv daim duab saum toj no, muaj lawv tus kheej tus IP chaw nyob - 10.0.0.2/24 ntawm S2 server и 10.0.0.3/24 ntawm S3 server. Chaw nyob 10.0.0.252/24 и 10.0.0.253/24 xaiv los ntawm Selectel rau routers L3VPN-1 и L3VPN-2, raws. IP chaw nyob 10.0.0.254/24 yog VRRP VIP chaw nyob ntawm Selectel routers.

Koj tuaj yeem kawm paub ntxiv txog qhov kev pabcuam L3VPN nyeem hauv peb qhov blog.

Ua ntej qhov hloov pauv, txhua yam zoo li kwv yees li hauv daim duab:

Ob lub routers L3VPN-1 и L3VPN-2 tau txuas nrog lub qub aggregation hloov А. Tus tswv rau VRRP VIP chaw nyob 10.0.0.254 yog lub router L3VPN-1. Nws muaj qhov tseem ceeb dua rau qhov chaw nyob no dua li lub router 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;
            }
        }
    }
}

S2 server siv lub rooj vag 10.0.0.254 los sib txuas lus nrog cov servers hauv lwm qhov chaw. Yog li, tshem tawm L3VPN-2 router los ntawm lub network (ntawm chav kawm, yog tias nws yog thawj zaug txiav tawm ntawm MPLS tus sau) tsis cuam tshuam rau kev sib txuas ntawm tus neeg siv khoom servers. Nyob rau ntawm no, lub Circuit Court redundancy theem tsuas yog txo.

Tom qab ntawd peb tuaj yeem rov txuas tau lub router zoo L3VPN-2 mus rau ib khub keyboards N. Lay txuas, hloov transceivers. Lub router lub logical interfaces, uas lub lag luam ntawm cov neeg siv kev pab cuam nyob ntawm, yog neeg xiam oob qhab kom txog rau thaum nws tau lees paub tias txhua yam ua haujlwm raws li nws yuav tsum tau ua.

Tom qab kuaj xyuas cov kev sib txuas, transceivers, theem teeb liab, thiab theem kev ua yuam kev ntawm cov interfaces, lub router tau muab tso rau hauv kev ua haujlwm, tab sis twb tau txuas nrog ib khub tshiab ntawm cov keyboards.

Tom ntej no, peb txo qis VRRP qhov tseem ceeb ntawm L3VPN-1 router, thiab qhov chaw nyob VIP 10.0.0.254 tau tsiv mus rau L3VPN-2 router. Cov haujlwm no kuj tau ua tiav yam tsis muaj kev cuam tshuam ntawm kev sib txuas lus.

Hloov chaw nyob VIP 10.0.0.254 mus rau lub router L3VPN-2 tso cai rau koj lov tes taw lub router L3VPN-1 tsis muaj kev cuam tshuam ntawm kev sib txuas lus rau cov neeg siv khoom thiab txuas mus rau ib khub tshiab ntawm kev sib sau ua ke N.

Txawm hais tias tsis xa rov qab VRRP VIP rau L3VPN-1 router yog lwm lo lus nug, thiab txawm tias nws rov qab los, nws ua tiav yam tsis muaj kev cuam tshuam kev sib txuas.

Tag nrho

Tom qab tag nrho cov kauj ruam no, peb tau hloov pauv cov kev sib sau ua ke hauv ib qho ntawm peb cov chaw khaws ntaub ntawv, thaum txo kev cuam tshuam rau peb cov neeg siv khoom.

Txhua yam uas tseem tshuav yog dismantling. Dismantling ntawm cov keyboards qub, dismantling ntawm qub kev sib txuas ntawm keyboards A thiab D, dismantling ntawm transceivers los ntawm cov kev sib txuas, kho cov kev soj ntsuam, kho cov duab kos duab hauv cov ntaub ntawv thiab saib xyuas.

Peb tuaj yeem siv cov keyboards, transceivers, patch cords, AOC, DAC sab laug tom qab hloov mus rau lwm qhov haujlwm lossis rau lwm qhov kev hloov zoo sib xws.

"Natasha, peb hloov txhua yam!"
