Soo-koobka dariiqyada DMVPN iyo khariidadda soo-koobka NHRP: shaxanno kala duwan
Soo-koobka dariiqyada wuxuu beddelaa prefix-ka la xayeysiiyay iyo tallaabada xigta. Khariidadda soo-koobka NHRP waxay beddeshaa waxa jawaabta xallinta soo celiso. Isla eray, shaxan kale.
Qof ayaa kaa codsanaya inaad soo koobto spoke-yada, tigidhka-na wuxuu ku xirmaa hub-ka oo leh prefix yar. Toddobaad kadib taraafikada laamaha dhexdooda ee horay si toos ah u mari jiray ayaa mar kale hub-ka mara, qofna lama xiro labada isbeddel. Erayga soo koob spoke-yada wuxuu daboolaa laba hawlgallo kala duwan oo taabta laba shaxan oo kala duwan. Sheeg xaaladda aad dhimayso ka hor intaadan amarro ka amaahan tusaale kale oo DMVPN ah.
Calaamadda: taraafikada tooska ah ee spoke waxay ku noqotay hub-ka
Farqigani wuxuu ugu muhiimsan yahay marka doodda Phase 2 lagu dabaqo naqshad Phase 3. Isla erayadu waxay ka muuqdaan labada wada-hadal, saameynta gudbinta-na isku mid ma aha.
Taasi waa sababta isbeddelku ugu muuqday mid sax ah markii la dib-u-eegayay: dib-u-eegistu waxay eegtay shaxda dariiqyada, taas oo kaliya mid ka mid ah saddexda xaaladood ee ku lug leh.
Hal isku-dubarid, laba shaxan
Labada hawlgallada waxay u eg yihiin sidan:
| 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 |
Soo-koobka dariiqyada waa hadal ku saabsan waxa hub-ku xayeysiiyo iyo waxa spoke-ka qaata u dhigto dariiq ahaan. Khariidadda soo-koobka NHRP waa hadal ku saabsan jawaabta uu spoke-ku diro marka spoke kale weydiiyo sida loo gaadho cinwaan. Kuwani waa su'aalo kala duwan oo leh habab guuldarro oo kala duwan, naqshaduna waxay beddeli kartaa mid iyada oo tan kale uga tagto sidii ay ahayd. In labadaba loo arko sidii hal tuuje waa dariiqa isbeddelka isku-dubaridku uu aamusnaan ugu noqdo isbeddel gudbin.
Mid ka mid ah hawlgallada dariiqa ilaalinta ma aha hadal ku saabsan, maxaa yeelay waxaa laga wada xaajoodaa peer-ka aad runtii xallisay.
Waxa soo-koobka hub-ka uu runtii beddelo
Hagaha Cisco ee khariidadaha soo-koobka NHRP ee u dhexeeya spoke-yada wuxuu qeexayaa habayn Phase 3 oo hub-ku ku xayeysiiyo soo-koob oo uu sii ahaado tallaabada xigta ee dariiqaynta. Markaas leexin iyo xallin NHRP oo xigta waxay bixiyaan dariiq gudbin oo toos ah. Sidaas darteed akhrinta kaliya dariiqa isku-dubaridan ma qeexayso dhammaan xaaladda gudbinta, ugamana jeeddo in pakad kastaa weligiis hub-ka maro. Soo-koobku wuxuu ku saabsan yahay gaaritaanka, ma aha dariiqa.
Sidaas darteed dib-u-eegis naqshadeed oo ku joogsata shaxda dariiqyada waxay ansixin kartaa isbeddel beddela hab-dhaqanka xallinta. Baadh dariiqa la doortay, natiijada NHRP iyo dariiqa ilaalinta sidii saddex indho-indheyn oo gaar ah.
Haddii aadan sheegi karin kee saddexda ka mid ah uu isbeddelay, ma aadan dhammaystirin isbeddelka.
Waxa khariidadda soo-koobka NHRP beddesho
Qaado spoke leh 10.32.0.0/19 oo u mara dhowr dariiqo LAN oo gaar ah, halka hub-ku u xayeysiiyo isku-dubarid weyn spoke-yada kale. Codsi 10.32.12.10 ah wuxuu haddii kale heli lahaa macluumaad xallin oo ku saabsan shabakadda yar ee u dhiganta. Astaanta la diiwaangeliyay ee khariidadda soo-koobka NHRP waxay u ogolaataa spoke-ka inuu beddelkiisa soo celiyo prefix-ka daboolka ee la habeeyay, taas oo yareyn karta shaqada xallinta ee soo noqnoqota ee shabakadaha ka tirsan spoke-kaas. Taasi kama dhigto soo-koobka dariiqyada hub-ka iyo soo-koobka xallinta spoke-ka isla shay.
Prefix-kaas daboolka sii qaab milki oo ula kac ah. Jawaab ballaaran oo ka mid ah cinwaanno kale leh, ama bannaan-gelyo aan la gaari karin, waxay taraafikada xigta u dirin kartaa peer aan ku habboonayn.
Hubi dariiqyada dhabta ah iyo kiisaska diidmada ee loogu talagalay ka hor intaadan weyneyn prefix-ka, ma aha kadib.
Isbarbar dhig meesha ugu horreysa iyo mid ku jirta soo-koobka
Dooro laba meelood: tan ugu horreysa ee aad tijaabisay, iyo mid kale oo ku jirta soo-koobka la soo jeediyay. Mid kasta, qor dariiqa la doortay, xaaladda NHRP ee loo isticmaalay gaaritaanka, iyo dariiqa jawaabta dhabta ah. Isbarbardhiggaasi wuxuu kuu sheegayaa haddii aad beddeshay miisaanka dariiqaynta, miisaanka xallinta ama khalad gudbin, taasna waa gabagabada kaliya ee faa'iido leh. Bandhig leh prefix yar ma aha caddayn mid ka mid ah kuwaas.
Xaqiiji wejiga la geeyay iyo hab-dhaqanka tallaabada xigta ee borotokoolka dariiqaynta ka hor intaadan tusaalaha Phase 3 ku dabaqin shabakaddaada. Tusaale gaaban ma aha caddayn in naqshad kale ilaaliso isla dariiqa tooska ah ee spoke.
Tigidhku waa inuu sheegaa shaxda aad dhimatay iyo tan aad iska tagtay. Wax kasta oo ka yar dib ayaa loo baari doonaa bil kadib laga bilaabo eber.
