Routes tau muab faib ua peb hom: txoj kev zoo li qub, txoj kev dynamic, thiab txoj kev ncaj nraim.
Nyob rau hauv txoj kev ntawm phau ntawv input static routing, thiaj li yuav daws tau qhov teeb meem routing ntawm tag nrho ip ntiaj teb no, nws yog heev tsis muaj zog nyob rau hauv kev muaj tiag.
Yog li, cov kws tshaj lij tau xav tias cia lub router los ntawm lub tsev, qhia rau lub router nyob ze, leej twg kuv nyob ib sab, kuv nyob ib sab, yog li tom qab ua tiav ntawm lub voj voog, lub rooj sib tham muaj, raws li txoj cai no, dynamic routing yog generated.
Qhov yooj yim tshaj plaws dynamic routing raws tu qauv yog hu ua RIP, uas yog hu ua "nyob deb vector raws tu qauv", thiab tam sim no peb siv nws upgraded version RIP2. Thaum peb hais tias cov txheej txheem routing yog qhov yooj yim lossis nyuaj, ib qho ntawm cov txheej txheem yog qhov nyuaj ntawm "txoj kev qhia tus nqi" algorithm uas tau teev tseg los ntawm txoj cai routing, thiab tus nqi algorithm ntawm RIP2 yog qhov yooj yim tshaj plaws.
Hauv RIP2, routers xa cov ntaub ntawv hu ua "vector deb" rau cov neeg nyob sib ze txhua 30 vib nas this, thiab lub rooj sib tham tsuas yog qhov chaw nyob tom ntej ntawm txoj kev zoo tshaj plaws mus rau qhov chaw. RIP2 Xaiv txoj kev zoo tshaj plaws raws li qhov tsawg kawg nkaus router hop suav. Piv txwv li, muaj ob txoj kev ntawm router A thiab router B. Ib txoj kev hla dhau 10 routers thiab lwm txoj kev hla dhau 8 routers. RIP2 txiav txim siab tias ip pob ntawv hauv A yuav tsum dhau los ntawm txoj kev thib ob kom ncav cuag router B
RIP2 tso cai rau ntau tshaj 15 hops. Ntau tshaj 15 hops suav hais tias tsis tuaj yeem ncav cuag. Tus tshiab ipv6-raws li RIP raws tu qauv RIPng tau txhim kho cov ntaub ntawv hom ntawv thiab chaw nyob muaj feem cuam tshuam li RIP2.
Simplicity yog ob qho tib si lub zog thiab qhov tsis muaj zog. Rau qhov loj IP network, tsuas yog tso siab rau tus naj npawb ntawm hops qhov kev ncua deb no los xaiv txoj hauv kev, ntau zaus yuav ua haujlwm me ntsis. Hauv tib qhov piv txwv, router A tuaj txog ntawm router B txoj kev 1 nrog rau qhov zoo li ntau ntawm hops, tab sis yog tias bandwidth loj dua li ntawm txoj kev 2, RIP2 yuav ua li cas?
RIP2 tseem yuav tawv ncauj xaiv txoj kev 2. Thiab qhov tseeb, txoj kev 2 tsis zoo. Yog li, RIP yog qhov tsim nyog rau cov tes hauj lwm me me, lossis ntawm ntug ntawm cov IP loj.
Zoo li qee yam ntawm peb cov khoom lag luam, nws muaj peev xwm teeb tsa qhov RIP dynamic routing raws tu qauv. Peb lwm cov khoom ONU yog: olt onu, ac onu, Kev sib txuas lus onu, optical fiber onu, catv onu, gpon onu, xpon onu, thiab lwm yam., tuaj yeem ua kom muaj kev txhawb nqa sib txawv rau ntau qhov chaw ntawm lub network, txais tos tuaj kawm ntxiv.
