Inqubomgomo yokuthumela yangaphandle ye-Junos: igama akusona isimo sokufanisa

Othile waqamba inqubomgomo ngegama elithi EXPORT-STATIC, wayinamathisela, futhi manje uyazibuza ukuthi kungani isiqalo esivela ku-VPN routing instance singafiki ngisho nakanye ekugcineni okude. Igama alinawo umthelela ekukhetheni. Inqubomgomo iyincazelo kanye nokunamathiselwa, futhi lokho ekukhiphayo kunqunywa yizimo zayo zokufanisa, imigomo yayo ehleliwe kanye nomongo oyisebenzisayo. Funda lezo zintathu ngalolo hlelo, futhi imfihlakalo ivamise ukuncipha ibe umgomo owodwa ongakaze ufanise.

Igama liyilebula, akusona isimo

I-Junos ayizihumushi izinhlobo zemigomo. Inqubomgomo obekungafaneleka ukuyibiza ngokuthi ukuthumela okumile ingafanisa neprotocol ethi static, noma ingafanisa nesiqalo sekheli, noma ingafanisi nalutho futhi yamukele konke okudlulayo. Ilebula iyidokhumenti ebhalwe yilowo oyidalile, futhi ithembekile ngendlela efanayo nenkumbulo yalowo muntu ngenhloso.

Thatha umphumela wokuthumela oyisimanga njengesicelo sokufunda incazelo, hhayi njengobufakazi bokuthi ukunamathiselwa kuphukile. Funda incazelo futhi uyivumele iphikisane nelebula.

Thola ukunamathiselwa ngaphambi kwemigomo

Incazelo efanele enamathiselwe endaweni engafanele ishintsha okunye ukushintshana. Thola ukuthi iyiphi i-routing instance, iprotocol kanye nomakhelwane noma iqembu elibhekisa ngempela kwinqubomgomo, ngoba inqubomgomo enamathiselwe ngaphansi kweqembu elilodwa le-BGP ayithinti elinye, futhi inqubomgomo enamathiselwe ku-instance ayisebenzi ngempela kuyo yonke iprotocol engaphakathi kwayo. I-Junos iyahlukanisa lawa mazinga, futhi ukuntuleka kokuthumela ezingeni leqembu kuvamile lapho inhloso ivezwe ezingeni le-instance.

Bhala indlela yokunamathiselwa phansi ngaphambi kokufunda umgomo owodwa. Ingxenye yalolu phenyo iphela lapho, incazelo ingakathintwa futhi isitatimende sokuthumela sisusiwe. Qopha umehluko kulogi yezinguquko ukuze kungabikho ozobuyisela emuva njengephutha.

Imigomo ihlolwa ngokulandelana, futhi isinqumo sokuqala siyawina

Imigomo ihamba kusukela kowokuqala kuya kowokugcina, futhi umgomo owamukelayo noma owenqabayo uyisinqumo sokugcina. Umgomo wakamuva obonakala njengokukhishwa okuhlosiwe awusoze wasebenza uma umgomo wangaphambili usuqume isiphetho somzila, yingakho inqubomgomo ingafundeka kahle kusukela phezulu kuya phansi kodwa iphathe ngokuphambene nenhloso. Hlola ukulandelana ngokuqondene nomzila okukhathazayo, hhayi ngokuqondene nokulandelana okufakwe ngakho imigomo.

Umgomo oshiya isenzo sawo awuqedi; ukuhlolwa kuqhubeka kumgomo olandelayo, futhi umphumela wokugcina uncike kulokho okulandelayo kanye nokuzenzakalelayo okusebenzayo. Lokho kuwukwakheka okuwusizo ngempela kanye nomthombo otherembile wokumangala lapho kungenzeki ngamabomu.

Isibonelo esithumela kuphela imizila emile, ukunamathiselwa kuseqembu:

policy-options {
    policy-statement EXPORT-STATIC {
        term statics { from protocol static; then accept; }
    }
}
protocols bgp group TO-PEER { export EXPORT-STATIC; }

Isiqalo esifundwe nge-OSPF esikhundleni sokuhlelwa njengomzila omile siyahluleka ekufaniseni futhi siwe, noma ngabe inqubomgomo ibizwa ngani.

Izenzo zishintsha ikhophi, hhayi umzila wangempela

Izenzo zenqubomgomo zisebenza kumzila ngendlela ohlolwa ngayo kulowo menyazo, okungukhophi hhayi umugqa osetafuleni lokuhlela. Ngakho-ke i-show route yasendaweni ingabonisa umzila onesethi eyodwa yezimiso ngenkathi inguqulo ethunyelwe ithwala ezinye, futhi owangempela awubhalwa kabusha ukuthumela. Lowo mehluko uchaza izingxoxo ezimbalwa zokuthi ubani umphumela wakhe ulungile: womabili alungile, futhi achaza izinto ezahlukene. Shono ukuthi yimuphi umbono oyicaphunayo njalo lapho onjiniyela ababili bengavumelani ngesimo somzila.

Ukwamukela nokwenqaba yizinqumo zokugcina; izinguquko zezimiso akudingekile ukuthi zibe njalo. Ungacabangi ukuthi ukusetha i-community kuqeda inqubomgomo, ngoba ukuhlolwa kungaqhubeka kumigomo ongayicabangile.

Qhathanisa umbono omenyaziwe nalokho okulindelekile

Sebenzisa umbono oqondene neprotocol kwi-peer yangempela, njenge-show route advertising-protocol bgp 192.0.2.1, futhi uwufunde kumongo ofanele we-routing instance. Umzila okhona ku-VRF awudingi ukuthi udlule inqubomgomo yokuthumela, futhi umzila ovela kumphumela omenyaziwe awudingi ukuthi wamukelwe yicala elikude. Lezi yizimo ezintathu ezihlukene futhi ziyahluleka ngezindlela ezahlukene.

Yamukela umklamo ngesiqalo esisodwa okumele simenyazwe nesinye okumele sihlale sisekhaya. Lokho kunikeza inqubomgomo isivumelwano ongasivivinya, futhi kugwema isisombululo esihlukile sokunweba ukuthumela kuze kube yilapho kugcina kuvela umzila owodwa oqanjiwe.
