Hoʻokaʻawale ʻia nā ala i ʻekolu ʻano: ala paʻa, ala paʻa, a me ke ala pololei.
Ma ke ala o ka manual input static routing, i mea e hoʻoponopono ai i ka pilikia routing o ka honua ip holoʻokoʻa, ua nāwaliwali loa i ka ʻoiaʻiʻo.
No laila, ua manaʻo ka poʻe akamai e hoʻokuʻu i ka mea alalai mai ka home, e haʻi i ka mea hoʻokele kokoke, ʻo wai wau e pili ana, ʻo wai wau e pili ana, no laila ma hope o ka pau ʻana o kahi pōʻai, loaʻa ka papa kuhikuhi, ma muli o kēia kumu. Hoʻokumu ʻia ke alahele dynamic.
ʻO ka protocol routing dynamic maʻalahi loa i kapa ʻia ʻo RIP, i kapa ʻia ʻo "distance vector protocol", a ke hoʻohana nei mākou i kāna hōʻano hou RIP2. Ke ʻōlelo mākou he maʻalahi a paʻakikī paha kahi protocol routing, ʻo kekahi o nā pae hoʻohālikelike ka paʻakikī o ka algorithm "routing comprehensive cost" i kuhikuhi ʻia e ka protocol routing, a ʻo ke ala ala ala algorithm o RIP2 ka mea maʻalahi.
Ma RIP2, hoʻouna nā mea hoʻokele i ka ʻike i kapa ʻia ʻo "distance vector" i nā mea hoʻokele e pili ana i kēlā me kēia 30 kekona, a ʻo ka papa kuhikuhi e mālama wale i ka helu hope-hop o ke ala maikaʻi loa i ke kahua e hele ai. RIP2 Koho i ke ala maikaʻi loa ma muli o ka liʻiliʻi o ka helu hop router. No ka laʻana, aia ʻelua ala ma waena o ka mea hoʻokele A a me ke alahele B. Hoʻokahi ala e hele ai ma waena o 10 mau ala ala a ʻo kekahi ala e hele ma 8 mau mea ala. Hoʻoholo ʻo RIP2 e hele ka ʻeke ip ma A ma ke ala ʻelua e hiki i ke alalai B
Hiki iā RIP2 ke kiʻekiʻe o 15 hops. ʻOi aku ma mua o 15 mau hops i manaʻo ʻia ʻaʻole hiki ke loaʻa. Ua hoʻomaikaʻi ka protocol RIP RIPng ipv6 hou i ka hōpili ʻike a me ka hoʻopuka ʻana i nā mea pili ma mua o RIP2.
ʻO ka maʻalahi ka ikaika a me ka nāwaliwali. No kahi pūnaewele IP nui, e hilinaʻi wale ana i ka helu o nā hops i kēia ʻāpana mamao e koho i kahi ala, i nā manawa he nui kahi hana. Ma ka laʻana like, hiki i ka mea hoʻokele A ma ke ala 1 o ka mea hoʻokele B me ka nui o nā hops, akā inā ʻoi aku ka nui o ka bandwidth ma mua o ke ala 2, he aha ka RIP2 e hana ai?
E koho paʻakikī ʻo RIP2 i ke ala 2. A ʻoiaʻiʻo, ʻaʻole maikaʻi ke ala 2. No laila, kūpono ʻo RIP no nā pūnaewele liʻiliʻi, a i ʻole ma ka lihi o nā pūnaewele IP nui.
E like me kekahi o kā mākou huahana onu, hiki ke hoʻonohonoho i kēia RIP dynamic routing protocol. ʻO kā mākou mau huahana ONU ʻē aʻe: olt onu, ac onu, Communication onu, optical fiber onu, catv onu, gpon onu, xpon onu, etc., hiki ke hana i nā kākoʻo like ʻole no nā kaiapuni like ʻole o ka pūnaewele, e hele mai e aʻo hou.
