Ukushintsha kwe-WAN ku-DMVPN: inqubomgomo yomzila noma ukuvala ithuneli?

Ihabhu le-DMVPN elinama-WAN amabili lishintsha liye kwelesekelo ngendlela eyodwa kwezimbili, futhi umehluko mkhulu kunalokho okubonakala. Enye ishintsha ukuthi iyiphi i-hop elandelayo ekhethwa inqubomgomo yomzila, ngakho amaphakethe ayaqhubeka nokugeleza futhi kushintsha kuphela indlela yokuthi aphume ngayo. Enye ivala ithuneli ngokokuphatha, okuholela ekutheni zonke izinsizakalo kuleyo interface zehle nayo. Zombili zingaba nembile, ngoba ziphendula imibuzo ehlukene.

Isinqumo siza ngaphambi kokumisa

Izimo ezintathu zininqumela lokhu. Ingabe kukhona okunye okuncike ekutheni i-interface yethuneli isebenza, njengephrofayili yesibili ye-DMVPN noma umqaphi ofunda isimo sayo? Ingabe ithrafikhi okufanele ishintshele kwelesekelo ithwele inqubomgomo yayo, noma incike kuthebula lomzila jikelele? Futhi ingabe umsebenzisi udinga ushintsho lwesimo olucacile, noma ukushintsha komzila okuthule kuyamukeleka? Phendula lezo zintathu futhi ukukhetha ngokuvamile kuzenzela kona.

Uma ukuvala kungaholela ekutheni izinsizakalo ezazisebenza zehle, inqubomgomo yomzila iyisenzo esincane. Uma imfuneko iwukuthi ithuneli lingabi khona ngenkathi i-WAN eyinhloko iphansi, akukho okufakwayo kwenqubomgomo okungakuchaza lokho.

Bhala impendulo phansi, ngoba ukumisa kuyingxenye elula.

Inqubomgomo yomzila ishintsha ini ngempela

Ekuhambiseni umzila okusekelwe kunqubomgomo, into elandelwayo ingalawula i-hop elandelayo. Okufakwe kumephu yomzila kusho ozokhetha ukuba yihop elandelayo kanye nento elandelwayo okufanele ibe isebenza ukuze isetshenziswe, futhi leso simo sokulandela sivela kusihloli se-IP SLA. Uma into yehla, okufakiwe kuyeka ukufanisa futhi iphakethe lihlolwa okulandelayo noma ithebula lomzila elijwayelekile.

Le mininingwane yokugcina iyamangaza abantu: inqubomgomo eyeka ukukhetha i-hop elandelayo ngokuvamile ivumela umzila ojwayelekile esikhundleni sokuvala ithrafikhi. Uma udinga umgodi omnyama lapho kuhluleka, kufanele uwubhale ngokwakho.

Isintaksi iyahluka phakathi kwamapulatifomu nezinguqulo, ngakho hlola umhlahlandlela wenguqulo oyisebenzisayo ngempela.

Ukuvala ithuneli kushintsha ini

Ukuvala i-interface kushintsha isimo sokuphatha. Zonke ithuneli, umzila nesikhathi esincike kuyo zehla ngesikhathi esisodwa, okuyikho kanye okufunayo uma ithuneli kuyinto okufanele inyamalale. I-EEM applet nayo iguqula inkinga ye-WAN ibe ukuphazamiseka okuhlanganisa nezinsizakalo ezingahlobene.

Uma uthatha le ndlela, khawulela i-applet ku-interface eyodwa naku-trigger eyodwa, gcina isimo sokuphatha sangaphambilini, chaza isenzo sokubuyisela, futhi qinisekisa ukuthi ama-flap aphindayo awakwazi ukuyifaka kumjikelezo.

Umyalo wokubuyisela obhalwe ngokuqinile nawo ungadlula ukuvalwa kwesondlo okwenziwe omunye umuntu.

Yenza isihloli sihambe ngomzila ocabangayo

Isihloli esilanda umzila ongcono kakhulu wamanje siyadlulela ku-WAN yesekelo kanye nakho konke okunye, bese sibika ukuthi eyinhloko inempilo ngoba ayisayisebenzisi.

Gxila isihloli ku-interface noma ikheli lomthombo lomzila oyihlolayo. Futhi hlola ukuthi siqondise kuphi, ngoba ukufinyelela i-hop elandelayo yomhlinzeki kufakazela okuncane kunokufinyelela insizakalo ithuneli elikho ngayo. Setha ukubambezeleka kokunyuka nokwehla ngamabomu: ukubambezeleka okufushane kokwehla kusabela ngokushesha futhi kuyahlokoma, kanti okude kubekezelela ukuntengantenga okuncane futhi kufihla ukwehluleka kwangempela. Umhlahlandlela we-Cisco wokulandela nokuhambisa umzila ngokwenqubomgomo ku-IOS XE ubhala izinhlanganisela ezisekelwayo, futhi isethi yezici kupulatifomu yakho inquma ukuthi yiziphi kuzo ongazisebenzisa.

Bhala womabili amanani okubambezeleka eceleni kwento elandelwayo, kungenjalo akekho ozokwazi ukuthi kungani yaziphatha kanjalo.

Nquma ukubuyisela, bese uqinisekisa

Ukubuyisela kufanele isinqumo sako. Isixhumanisi esiqhubeka sinqamula umkhawulo singahambisa amaseshini kaningi kunaleso esihluleke ngokucacile, futhi ukuhambisa ngakunye kudla ukuxoxisana kabusha kwezokhiye nokuzama kabusha kohlelo. Khetha imfuneko yokuzinza bese uvumela ukubambezeleka ukuyiveza. Bese uqinisekisa phakathi newindi lokushintsha ngomzila wesihloli ubonakala: umzila okhethiwe, umzila womlingani wangaphandle nokuthi uhlelo lwenze ini ngempela.

Uma i-failover isebenza kodwa uhlelo lusaphuka, inkinga ingaphezu kwengqimba yomzila futhi akukho ukulandela okuzokulungisa.

Gcina ubufakazi besuka kulelo windi, ngoba ushintsho olulandelayo luzoqathaniswa nabo.
