Isifinyezo semizila ye-DMVPN nasebalazweni sesifinyezo se-NHRP: amathebula ahlukene
Isifinyezo semizila sishintsha isiqalo esimemezelwayo kanye nokugxuma okulandelayo. Ibhalaza lesifinyezo se-NHRP lishintsha lokho impendulo yokuxazulula ekubuyisayo. Igama elifanayo, ithebula elihlukile.
Othile ucela ukuthi ufingqe ama-spoke, futhi ithikithi livalwa ngamaqalo ambalwa ku-hub. Ngemva kweviki, ukuhamba phakathi kwamagatsha obekuhamba ngqo kubuyela ku-hub futhi, futhi akekho oxhumanisa lezi zinguquko ezimbili. Umusho ukufingqa ama-spoke uhlanganisa imisebenzi emibili ehlukene ethinta amathebula amabili ahlukene. Shono ukuthi yisiphi isimo osinciphisa ngaphambi kokuboleka umyalo kusibonelo esinye se-DMVPN.
Uphawu: ukuhamba okuqondile kwama-spoke kubuyele ku-hub
Lo mehluko ubaluleka kakhulu lapho ingxoxo ye-Phase 2 isetshenziswa kumklamo we-Phase 3. Amagama afanayo avela kuzo zombili izingxoxo, futhi umphumela ekudlulisweni awufani.
Yikho futhi ukuthi ushintsho lwabonakala lulungile ngesikhathi lubuyekezwa: ukubuyekeza kwahlola ithebula lemizila, okuyisimo esisodwa kuphela kwezintathu ezihilelekile.
Ukuhlanganisa okukodwa, amathebula amabili
Imisebenzi emibili ibukeka kanje:
| Operation | What it actually changes |
|---|---|
| Routing summary | Aggregates the prefixes the routing protocol advertises and changes the next hop the receiver installs |
| NHRP summary map | Changes the network returned in a resolution reply, so a requesting spoke resolves to a different address |
| Protection path | IPsec state for the peer you actually resolved; neither aggregation changes it |
Isifinyezo semizila siyisitatimende mayelana nalokho i-hub ekumemezelayo nalokho i-spoke eyamukelayo ekufaka njengomzila. Ibhalaza lesifinyezo se-NHRP siyisitatimende mayelana nempendulo i-spoke eyithumelayo lapho enye i-spoke ibuza ukuthi kufinyelelwa kanjani ikheli. Le yimibuzo ehlukene enezindlela zokwehluleka ezihlukene, futhi umklamo ungashintsha okukodwa kuyilapho ushiya okunye kunjalo nje ngqo. Ukuziphatha njengolawulo olulodwa yiyo indlela ushintsho lokuhlanganisa oluba ushintsho lokudlulisa buthule.
Akukho kule misebenzi emibili okuyisitatimende ngendlela yokuvikela, ngoba ixoxiswanwa nge-peer oyixazulule ngempela.
Yini isifinyezo ku-hub esiyishintshayo ngempela
Umhlahlandlela we-Cisco mayelana namabhalaza esifinyezo se-NHRP phakathi kwama-spoke uchaza ukuhlelwa kwe-Phase 3 lapho i-hub imemezela isifinyezo futhi ihlala iyikugxuma okulandelayo kokudlulisela. Ukudlulisela kabusha nokuxazulula kwe-NHRP okulandela lokho kunikeza indlela yokudlulisa eqondile kakhulu. Ngakho ukufunda kuphela umzila ohlanganisiwe akusichazi sonke isimo sokudlulisa, futhi akusho ukuthi wonke amaphakethe kufanele adlule ku-hub unomphela. Isifinyezo sikhuluma ngokufinyeleleka, hhayi ngendlela.
Yikho ukubuyekezwa komklamo okuma ethebuleni lemizila kungase kuvume ushintsho olushintsha indlela yokuxazulula. Hlola umzila okhethiwe, umphumela we-NHRP nendlela yokuvikela njengezinto ezintathu ezihlukene zokubheka.
Uma ungakwazi ukusho ukuthi yikuphi kokuthathu okushintshile, awukakaqedi ushintsho.
Yini ibhalaza lesifinyezo se-NHRP eliyishintshayo
Thatha i-spoke ephethe i-10.32.0.0/19 ngemizila eminingana ye-LAN eqondile kakhulu, kuyilapho i-hub imemezela ukuhlanganisa okukhudlwana kwamanye ama-spoke. Isicelo se-10.32.12.10 besizothola imininingwane yokuxazulula yenethiwekhi encane ehambisanayo. Isici esibhaliwe sebhalaza lesifinyezo se-NHRP sivumela i-spoke ukuthi ibuyisele isiqalo sayo sokumboza esilungisiwe esikhundleni salokho, okungase kunciphise umsebenzi wokuxazulula ophindaphindayo wamanethiwekhi angaphansi kwaleyo spoke. Lokho akukwenzi isifinyezo semizila se-hub nesifinyezo sokuxazulula se-spoke kube into eyodwa.
Nikeza leso siqalo sokumboza imodeli yobunikazi ehlosiwe. Impendulo ebanzi ehlanganisa amakheli angakwelinye indawo, noma izikhala ezingafinyeleleki, ingase ithumele ukuhamba okulandelayo ku-peer engafanele.
Hlola imizila yangempela nezimo zokwenqaba ezihlosiwe ngaphambi kokukhulisa isiqalo, hhayi ngemva.
Qhathanisa indawo yokuqala eyodwa kanye nendawo engaphakathi kwesifinyezo
Khetha izindawo ezimbili: eyokuqala oyihlolile, nenye engaphakathi kwesifinyezo esiphakanyisiwe. Kwesinye ngasinye, bhala umzila okhethiwe, isimo se-NHRP esisetshenziselwe ukufinyelela kuwo, nendlela yangempela yempendulo. Lokho kuqhathanisa kukutshela ukuthi ushintshe isikali semizila, isikali sokuxazulula noma iphutha lokudlulisa, futhi yisona kuphela isiphetho esiwusizo. Isibonisi esiqalo esincane asibona ubufakazi bakho konke lokho.
Qinisekisa isigaba esisetshenzisiwe nokuziphatha kokugxuma okulandelayo komthetho wemizila ngaphambi kokusebenzisa isibonelo se-Phase 3 kunethiwekhi yakho. Isibonelo esifushane asibona ubufakazi bokuthi omunye umklamo ugcina indlela efanayo eqondile ye-spoke.
Ithikithi kufanele lisho ukuthi yiliphi ithebula olinciphise nelinye olilishiyile. Noma yini encane kunalokho izobuyekezwa kusukela ekuqaleni ngemva kwenyanga.
