I-DMVPN enezigaba: ifu elilodwa ngobudlelwano bomhubhe ngamunye

Inodi yegatsha ibhalisa ngempumelelo ku-hub yesifunda sayo kodwa ayikwazi ukufinyelela isevisi kwesinye isifunda. Umhubhe uyasebenza, isimo se-NHS sibonakala siphilile, futhi ukwehluleka kuvela kuphela ezindaweni eziwela umngcele wesigaba. Leli phethini ngokuvamile lisho ukuthi umklamo awuzange ucacise ukuthi yimaphi amadivayisi abamba iqhaza kweliphi ifu le-DMVPN, ngakho amazinga akhiwe ngomqondo futhi manje awahambisani.

Uphawu luvela emngceleni wezigaba

Kumklamo onezigaba, i-hub emaphakathi, ama-hub ambalwa esifunda kanye namagatsha amaningi ngamunye unendawo yawo. I-hub yesifunda ingaba nobudlelwano bomhubhe obungaphezu kwesinye, futhi amagatsha awadingi ukubhalisa kuyo yonke indawo yokugcina emaphakathi. Izindlela ezibalulekile zisuka egatsheni ziye kwisevisi yesifunda, zisuka egatsheni ziye kwenye inodi yesifunda egunyaziwe, futhi zisuka egatsheni ziye endaweni emaphakathi.

Lapho enye yalezi zindlela yehluleka kanti ezinye ziyasebenza, inkinga cishe njalo ayiyona umhubhe ophukile, kodwa incazelo yendima engekho noma ephikisanayo. Bhala izindlela ezihlosiwe bese uziqhathanisa nalokho amadivayisi akwakhile ngempela. Lokho kuqhathanisa kuthatha ihora futhi kuvimbela iviki lokucabanga. Kuyigcine kanye nedokhumenti yomklamo.

Ifu elilodwa, isivumelwano se-interface esisodwa

Kuyo yonke ifu, rekhoda i-interface yomhubhe, ukukhethwa kwamakheli esigaba esiphezulu, umthombo wendawo wenethiwekhi engaphansi, ubudlelwano be-NHS ne-NBMA, ukusatshalaliswa kwe-multicast kanye nenqubomgomo yokuvikela. Shiwo futhi ukuthi yimiphi imizila ewela phakathi komongo wesifunda nowemaphakathi, ngoba lowo musho uwumklamo uqobo.

I-hub yesifunda enama-interface amabili omhubhe idinga izivumelwano ezimbili, hhayi esisodwa esinamakheli amabili. Umthombo wenethiwekhi engaphansi, isizinda se-NHRP kanye nemizila kungahluka nge-interface ngayinye, futhi idokhumenti ezihlanganisa ndawonye izodukisa lowo ohlela eyesibili.

Ama-ID ingumongo wendawo, hhayi ukulawula ukufinyelela

Ama-ID enethiwekhi e-NHRP nezinkinobho ze-GRE yizinto ezimbili ezivame ukuthathwa ngokungalungile njengezilungiselelo zomhlaba wonke. Umhlahlandlela we-NHRP ku-IOS XE uchaza i-ID yenethiwekhi njengenengqondo yendawo, ngakho izinombolo ezifanayo kuma-router akude azifakazeli lutho futhi ukushintsha inombolo yendawo ye-router eyodwa akudali umngcele wokufinyelela.

Ukinobho we-GRE, lapho umklamo usebenzisa khona eyodwa, usiza ukukhomba umongo womhubhe owamukayo, futhi kuvunyelwana ngawo phakathi kwamaphoyinti okugcina abelana lowo mongo. Akulona iphasiwedi futhi akuthathi indawo yokuqinisekisa i-IKE noma inqubomgomo yomzila. Thatha zombili lezi zinto njengomongo wokuhlela okufanele uhambisane ngaphakathi kobudlelwano, hhayi njengezilawuli zokuphepha ezihlukanisa izifunda.

Hlela phakathi kwezigaba ngamabomu

Nquma ukuthi yimiphi imikhawulo i-hub yesifunda eyimemezelayo iye phezulu kanye nokuthi yiziphi izindawo ezimaphakathi ezinikeza amagatsha ayo. Bese uhlola ukugxuma okulandelayo kwangempela kanye nokuziphatha kwendlela emfushane okuqondene nesigaba somzila ngamunye, ngoba umzila ofingqiwe nendlela emfushane kungakhiqiza ukudluliswa okuhluke kakhulu kunalokho okushiwo umdwebo.

Sebenzisa ukuhlela ngenqubomgomo yokufinyelela ukuphoqelela ukuhlukaniswa kwezifunda. Uma igatsha kungafanele lifinyelele esifundeni esinye ngqo, umzila nenqubomgomo kufanele kusho lokho, esikhundleni sokuthembela ku-ID engakaze yakhelwe ukuphoqelela lokho. Bhala inqubomgomo eduze kwe-ID. Uma kungenjalo unjiniyela olandelayo uzocabanga ukuthi inombolo yiyo eyenza umsebenzi.

Hlola indlela emfushane engalindelekile

Lapho igatsha lizama ukwakha ubudlelwano obuqondile nendawo yokugcina emaphakathi, hlola umzila walo, ukumephwa kwe-NHRP kanye nomongo womhubhe okhethiwe ngaphambi kokushintsha ama-ID ngokuzenzakalela. Ukungafinyeleleki, ubudlelwano be-NHS obungahlosiwe kanye nendlela emfushane esemthethweni kodwa engagunyaziwe kudinga izilungiso ezintathu ezihlukene.

Umhlahlandlela wokuhlela we-DMVPN ukhombisa izilungiselelo zomhubhe ne-NHRP ndawonye, futhi yingakho kufanele kuqala kuhlukaniswe izimo ephepheni. Rekhoda izivumelwano zefu, gcina imizila yezigaba icacile, futhi ukwehluleka komngcele okulandelayo kuzoba nendawo yokukhomba.
