DMVPN wejiga 3: akhrinta wadada gaaban labada jiho
Hal ping oo toos ah ma caddeeyo wadada gaaban ee DMVPN wejiga 3. Soco wadada horay iyo gadaal, kadib si gooni ah u akhri xaaladda NHRP, wadada iyo IPsec.
Waxaad aragtaa hal ping oo ka socda spoke ilaa spoke, waxay qaadataa wadada dheer iyada oo maraysa hub, tan labaadna si toos ah ayay u socotaa. Waa laga yaabaa in waqtigaas lagu dhawaaqo in wadada gaaban ay shaqeyneyso. Gabagabadaas waa badh sax. Wadada horay waxay noqon kartaa wadada gaaban halka wadada gadaal ay wali marto hub, iyo xaaladda caddeyneysa jiho kasta waa xaalad kale. Soco labada jiho oo akhri saddex shax ka hor inta aadan aqbalin nashqadda inay caafimaad qabto.
Ka bilow wadada baakadda ee aad dhab ahaan arki karto
Ka bilow spoke leh meel loo socdo oo ay tahay inay toos noqoto. Raac baakadda ugu horreysa: waxay raacdaa wadada spoke ee ku socota hub, sababtoo ah wali ma jirto wadada gaaban. hub waxay u gudbisaa horay, nashqadda wejiga 3-na waxay sidoo kale u dirtaa isha leexin sheegaysa in jid wanaagsan uu jiro.
Leexintaas waa kicinta, ma aha caddaynta. Waxay sheegtaa in hub uu arkay taraafik la hagaajin karo. Ma sheegto in isha ay dhistay wadada gaaban, in meesha loo socdo ay ka jawaabtay xallinta, ama in wadada jawaabtu ay isticmaasho.
Marka fiirsashada ugu horreysa ee faa'iidada leh waa ka hor iyo ka dib: qulqulka ugu horreeya ee hub mara, qulqulka dambe si toos ah.
Saddex xaaladood oo u eg hal tunnel
Wadada gaaban waxay ku xiran tahay saddex qaybood oo xaalad ah, mid kastaana wuxuu leeyahay noloshiisa iyo amarkiisa.
| State | What it answers | Where to read it |
|---|---|---|
| NHRP cache | Which transport address maps to this overlay address | show ip nhrp |
| Route or shortcut | Where one specific inner prefix is forwarded | show ip route 10.10.20.5 |
| IPsec association | Which peer traffic is protected, and by which SA | show crypto ipsec sa peer 203.0.113.5 |
Gelinta kaydka NHRP waxay isku xirtaa cinwaanka overlay iyo cinwaanka gaadiidka NBMA. Waddo ama wadada gaaban ayaa go'aamisa halka hal bartilmaameed gudaha loo gudbiyo. Ururka IPsec wuxuu ilaaliyaa taraafik kasta oo ka soo baxa. Jawaab maqan waxay ka iman kartaa mid ka mid ah saddexda, amarkaantuna waxay sheegaan midka maqan.
Ku akhri sidaas oo kale, waayo khariidad maqan ayaa labada kale ka dhigta mid aan xiiso lahayn.
Soco codsiga iyo jawaabta si gooni ah
Ka bilow spoke A, weydii xallinta oo fiiri waxa soo noqda. Codsigu wuxuu maraa wadada gudbinta NHRP ee la taageeray, meesha loo socdona waxay si toos ah uga jawaabi kartaa halkii ay hub marin lahayd. Isma-dheellitirnaantaas waa caadi, taasina waa sababta jawaabtu u tahay badhka xiisaha leh ee is-dhaafsiga.
Hadda doorarka beddel. Ka dir B ilaa A oo ku celi saddexda akhris. Nashqad hal jiha ka dhigta mid gaaban oo tan kale ka dhigta mid aan ahayn ma aha isku mid, isma-dheellitirnaantuna waxay inta badan ka timaadaa horgale maqan oo dhinac ah ama xallin aan waligeed jawaab helin.
Jawaabta dhinaca kale uma baahna inay hub marto kaliya sababtoo ah codsigu wuu maray. Ha u akhrin taas khalad oo ha bilaabin inaad dabo gasho cillad waddo oo aan jirin.
Akhri leexinta hub, ma aha oo kaliya wadadiisa
Shaxda waddooyinka hub waxay sheegtaa halka hub baakad u dirayo. Leexintu waxay sheegtaa waxa hub ka codsaday isha inay ka sameyso arrintaas. Kuwani waa xaqiiqooyin kala duwan, hub leh waddo sax ah laakiin aan leexin dirayo wuxuu qulqul kasta ku hayn doonaa wadada dheer aan xad lahayn. Hubka dhacdooyinka NHRP ee hub ka eeg oo xaqiiji in leexinno loo abuurayo taraafikada aad danaynayso.
Wejiga 3 wuxuu sidoo kale beddelaa macnaha soo koobidda. Habka wadada gaaban, spokes uma baahna shaxda buuxda ee waddooyinka fog ee gaarka ah ee nashqadda wejiga 2 ay filaysey, sidaas darteed waddo la soo koobay oo spoke ku taal si otomaatig ah ma aha shabakad maqan. Xaqiiji wejiga iyo siyaasadda waddooyinka ka hor inta aadan u akhrin soo koobidda cillad.
Ismaandhaafkaas kaliya ayaa abuura tikidhada DMVPN badan wax kasta oo kale.
Diiwaangeli gabagabada sida shay maqan
Ku dhammee qulqulka abka ee la ogolaaday iyo jawaabtiisa, oo qor jiho kasta inay isticmaashay wadada tooska ah iyo in kale. Kadib qor gabagabada sida shayga maqnaa: khariidad, wadada gaaban ee gudbinta, ururka ilaalinta ama jawaabta abka.
Derisnimo waddooyin iyo urur ammaan la wadaago waa caddayn caafimaad, ma aha caddayn wadada. Labaduba waxay noqon karaan kuwo qumman halka baakad kastaa uu wali qaadanayo wadada dheer. Marka hore hubi go'aanka gudbinta, kadib ururka qaada. Nidaamka ayaa muhiim ah, waayo ururku si kastaba wuu sameysmaa.
Caadadaas waxay faa'iido leedahay tikidhka xiga. «Tunnel-ka wuu kor yahay laakiin wuu gaabis yahay» wuxuu noqdaa «B ma laha wadada gaaban ee martida A», jumladna labaad waa sixid shan daqiiqo ah. Kaydi soo-saarka amarka oo la soco gabagabada, oo halkaas ku hay hagaha wejiga 3 ee iibiyaha.
