Njira zimagawidwa m'mitundu itatu: njira yokhazikika, yosunthika, komanso yolunjika.
Mu njira ya manual input static routing, kuti athetse vuto la mayendedwe a dziko lonse la ip, ndilofooka kwambiri kwenikweni.
Kotero, akatswiri anaganiza zolola rauta kuchokera kunyumba, auze rauta yapafupi, yemwe ine ndiri pafupi naye, yemwe ine ndiri pafupi naye, kotero kuti pambuyo pomaliza bwalo, tebulo loyendetsa likupezeka, malinga ndi mfundo iyi, dynamic routing imapangidwa.
Njira yosavuta yosinthira imatchedwa RIP, yomwe imatchedwa "distance vector protocol", ndipo pakali pano timagwiritsa ntchito RIP2 yake yokwezedwa. Tikamanena kuti njira yoyendetsera njira ndi yosavuta kapena yovuta, chimodzi mwazotsatira ndizovuta za "routing comprehensive cost" zomwe zimatchulidwa ndi ndondomeko yoyendetsera njira, ndipo njira yamtengo wapatali ya RIP2 ndiyosavuta.
Mu RIP2, ma routers amatumiza zomwe zimatchedwa "vector yakutali" kwa ma routers oyandikana nawo masekondi 30 aliwonse, ndipo tebulo lolowera limasunga adilesi yotsatira ya njira yabwino kwambiri yopita kumalo komwe mukupita. RIP2 Imasankha njira yabwino kwambiri kutengera kuchuluka kwa router hop. Mwachitsanzo, pali njira ziwiri pakati pa router A ndi router B. Njira imodzi imadutsa ma routers 10 ndipo njira ina imadutsa ma routers 8. RIP2 imatsimikiza kuti ip paketi mu A iyenera kudutsa njira yachiwiri kuti ifike rauta B
RIP2 imalola kuti pakhale ma hop 15. Ma hop opitilira 15 amawonedwa ngati osafikirika. IPv6-based RIP protocol RIPng yasintha mawonekedwe azidziwitso ndi ma adilesi okhudzana ndi RIP2.
Kuphweka ndi mphamvu komanso kufooka. Kwa netiweki yayikulu ya IP, kungodalira kuchuluka kwa ma hops mtunda uwu kuti musankhe njira, nthawi zambiri zimakhala zovuta. Muchitsanzo chomwecho, router A ikufika pa njira ya 1 ya router B ndi chiwerengero chowoneka ngati chachikulu, koma ngati bandwidth ndi yaikulu kwambiri kuposa njira ya 2, kodi RIP2 idzachita chiyani?
RIP2 idzasankhabe njira 2. Ndipo kwenikweni, njira ya 2 si yabwino. Choncho, RIP ndi yoyenera kwa maukonde ang'onoang'ono, kapena m'mphepete mwa ma IP akuluakulu.
Monga zina mwazinthu zathu za onu, ndizotheka kukonza njira yosinthira ya RIP iyi. Zogulitsa zathu zina za ONU ndi: olt onu, ac onu, Communication onu, optical fiber onu, catv onu, gpon onu, xpon onu, ndi zina zotero, zimatha kupanga chithandizo chosiyana siyana pa intaneti, kulandiridwa kuti mubwere kudzaphunzira zambiri.
