Gcina amarejista amabili emizila elabhorethri ye-IPsec: isisekelo nesivikelwe
Amarejista amabili: elilodwa lifinyelela kumlingani, elinye lithwala iziqalo zangasese. Landelela womabili, futhi thatha ukusatshalaliswa kabusha njengesinqumo senqubomgomo, hhayi indlela emfushane.
Imibuzo emibili iyahlangana elabhorethri ye-IPsec: ukuthi iphakethe lifinyelela kanjani ikheli langaphandle lomlingani, nokuthi lifinyelela kanjani amanethiwekhi angasese ngemuva kwalowo mlingani. Zingezincwadi zamarejista ahlukene, ngoba izinqubo zokuhambisa ezihlukene ziyaziphendula futhi zihluleka ngezimpawu ezihlukene. Gcina irejista yesisekelo yamaphoyinti okugcina angaphandle kanye namagxathu alandelayo afinyelela kuwo. Gcina irejista yengqimba ephezulu yeziqalo ezivikelwe, amasango azo kanye nomzila ohlosiwe odlula emhubheni. Iningi lokudideka elabhorethri livela ekufundeni umzila okhona ngokusemthethweni kwirejista eyodwa njengobufakazi ngomunye.
Amarejista amabili, imibuzo emibili
Amarejista ahlala emfushane ngokwanele ukuba agcinwe ngesandla ngesikhathi ilabhorethri incane, futhi yilapho esebenza kahle kakhulu. Amakholomu amabili anele: yini umbhalo, nokuthi ufinyelelwa kanjani.
| Ledger | What it lists |
|---|---|
| Underlay | Each gateway's external address and the next hop that reaches it |
| Protected | Each private prefix, its local gateway and its intended path through the tunnel |
Bhala izinhlangothi zombili. Isiqalo esikwirejista yokuphuma kodwa hhayi kwirejista yokubuya sidala umhubhe othwala izicelo futhi ulahle izimpendulo. Lesi simo sokusebenza engxenyeni siwumphumela ojwayeleke kakhulu elabhorethri, futhi kulula ukusithatha ngephutha njengenkinga yenqubomgomo.
Bhala indawo yokuya ngaphambi kwesivumelwano
Qala ngezindawo okuyiwa kuzo, hhayi ngezivumelwano. Kumsango ngamunye, bhala ikheli langaphandle kanye negxathu elilandelayo elifinyelela kuwo. Bese ubhala isiqalo ngasinye sangasese, isango laso lendawo kanye nomzila okufanele uwudlule emhubheni.
Ukwenza lokho ngaphambi kokukhetha isivumelwano sokuhambisa kugcina ingxoxo ithembekile. Ukwakhiwa kufika nezidingo, hhayi izintandokazi. Ingxoxo yokuthi yisiphi isivumelwano okufanele sisetshenziswe iba umbuzo wokuthi isiphi isidingo sinzima ngempela.
Kumile noma kuguquguquka, kunqunywa ngejista ngayinye
Ukuhambisa okumile ohlangothini lwezokuthutha ngokuvamile kulungile elabhorethri: amaphoyinti amabili okugcina, igxathu elilodwa elilandelayo, akukho okufanele kuhlangane. Uhlangothi lwangasese lungaba nokuguquguquka ngokunengqondo, ngoba iziqalo ziyafika futhi zihambe nomsebenzi. Ukuqhuba isivumelwano esisodwa sokuhambisa ohlangothini lwezokuthutha nesinye ohlangothini lwangasese akukupheleli ukuthi usabalalise kabusha phakathi kwazo, futhi ukuthatha ukusatshalaliswa kabusha ngokuhlanganyela njengombandela we-IPsec yilapho amalabhorethri eqala khona ukukhiqiza imiphumela okungekho muntu ongayichaza.
Nquma amarejista amabili ngokwahlukana futhi bhala ukuthi yiliphi eliguquguqukayo. Impendulo eyodwa yezinhlangothi zombili ngokuvamile isho ukuthi imibuzo emibili ayikaze yehlukaniswe ngempela.
Ukusatshalaliswa kabusha kunomngcele wenqubomgomo
Lapho imizila kufanele iwele, yenza ukuwela kube yinqubomgomo eneziqalo eziqanjiwe, isiqondiso, ukuphathwa kwemethrikhi kanye nomlindi womjikelezo. Uhlu lweziqalo namamephu emizila kunikeza konke kune, futhi amathegi agcina umzila osatshalaliswe kabusha waziwa ngemuva kokulahlekelwa umongo wawo wangempela. Funda incazelo ngokucophelela, ngoba azikwazi ukushintshana: ukwenqatshwa kwe-ACL ngaphakathi kwesigaba sokufanisa kusho ukuthi umzila awufani futhi ukuhlolwa kuyaqhubeka, kuyilapho ukulandelana kokwenqatshwa kumephu yomzila kuvimbela umzila ukuba usatshalaliswe kabusha nhlobo. Umhlahlandlela wamamephu emizila wokusatshalaliswa kabusha uhlanganisa lezo zigaba kanye nezinguquko zezici ezihamba nazo.
Bese uqhathanisa ithebula lokuhambisa eliwumphumela namarejista womabili. Ilabhorethri eqala ukudlulisela ngemuva kokusatshalaliswa kabusha okubanzi ikhombisile ukufinyeleleka, hhayi inhloso. Noma yimuphi umbhalo kuthebula ongaveli kuzo zombili izincwadi usho ukuthi ukuthunyelwa ngaphandle kubanzi kunokwakhiwa, futhi isimemezelo ngasinye sakamuva sizuzwa lokho kungacaci.
Gcina isibonelo sokuvikela sisesikhathini njengokuhambisa
Imihlahlandlela emidala encike kuma-algorithm abuthaka noma emfihlweni wokubonisa owabiwe iyimibono yomlando. Ukuyikopisha elabhorethri ohlose ukuyandisa kuyindlela amanani aphansi abuthaka aphila ngayo ekukhiqizeni. Sebenzisa inqubomgomo esekelwa yipulatifomu futhi bhala inguqulo oyihlolile, ngoba ilabhorethri iphila isikhathi eside kunesifundo.
Yamukela ukugeleza okukodwa okugunyaziwe kusuka kusibungu kuya kusibungu, ukuthutha kwayo okubuya, kanye nendawo eyodwa okufanele ihlale ngaphandle kobubanzi bokuvikela. Gcina umthombo womzila kanye nezinto ezikhethiwe okuxoxiswene ngazo kunye nomphumela ngamunye, ukuze irekhodi likhombise ukuthi yiluphi ungqimba olufakazelwe, hhayi ukuthi yiluphi ungqimba olwaluvele lusebenza.
Uma okuthile kuphuka, irejista itshela ukuthi yiluphi ungqimba okufanele luvulwe. Ukungafinyeleli kumlingani ukuthutha, ukungabi khona komzila wangaphakathi umzila wangasese, futhi umzila okhona ngaphandle kwesikhethi esifanisayo inqubomgomo. Imisho emithathu, ukuxilongwa okukodwa, akukho ukuqagela.
