Nzira dzakakamurwa kuita mhando nhatu: static nzira, ine simba nzira, uye yakananga nzira.
Munzira yekunyora manyorero static routing, kuitira kugadzirisa dambudziko rekufambisa renyika yese ip, haina kusimba muchokwadi.
Saka, nyanzvi dzakafunga kurega router kubva kumba, taurira router iri pedyo, ini ndiri pedyo naye, uyo wandiri pedyo naye, kuitira kuti mushure mekupedzwa kwedenderedzwa, tafura yekufambisa inowanikwa, zvichienderana nemutemo uyu. dynamic routing inogadzirwa.
Iyo yakapfava ine simba yekufambisa protocol inonzi RIP, inodaidzwa kuti "distance vector protocol", uye isu parizvino tinoshandisa yakakwidziridzwa vhezheni RIP2. Kana tichiti routing protocol iri nyore kana yakaoma, imwe yemaitiro ndeyekuoma kwe "routing comprehensive cost" algorithm inotarwa neprotocol yenzira, uye nzira inodhura algorithm yeRIP2 ndiyo yakapfava.
MuRIP2, marouters anotumira iyo inonzi "kure vector" ruzivo kune vavakidzani routers masekondi makumi matatu ega ega, uye tafura yenzira inochengeta chete kero inotevera-hop yenzira yakanakisa yekuenda kunzvimbo yekuenda. RIP2 Inosarudza yakanakisa nzira yakavakirwa pane shoma router hop count. Semuenzaniso, kune nzira mbiri pakati pe router A uye router B. Imwe nzira inopfuura ne10 routers uye imwe nzira inopfuura ne8 routers. RIP2 inosarudza kuti ip packet muA inofanira kupfuura nenzira yechipiri kusvika kune router B
RIP2 inobvumira huwandu hwegumi neshanu hops. Zvinopfuura 15 hop dzinoonekwa sedzisingasvikike. Iyo itsva ipv6-yakavakirwa RIP protocol RIPng yakavandudza fomati yeruzivo uye kero ine hukama pane RIP2.
Kupfava isimba uye utera. Kune yakakura IP network, kungovimba nenhamba yehops iyi chinhambwe paramende kusarudza nzira, mune dzakawanda zviitiko zvichave zvishoma zvebasa. Mumuenzaniso mumwechete, router A inosvika panzira yeB router 1 ine nhamba inoratidzika yakakura yehops, asi kana bandwidth yakakura kudarika iyo yenzira 2, RIP2 ichaita sei?
RIP2 icharamba yakasindimara kusarudza nzira 2. Uye chokwadi, nzira 2 haina kunaka. Naizvozvo, RIP inokodzera madiki network, kana kumucheto kwehombe IP network.
Kufanana nezvimwe zvezvigadzirwa zvedu zveonu, zvinogoneka kugadzirisa iyi RIP dynamic routing protocol. Zvimwe zvigadzirwa zvedu zveONU ndezvi: olt onu, ac onu, Kukurukurirana onu, optical fiber onu, catv onu, gpon onu, xpon onu, nezvimwewo, zvinogona kuita tsigiro yakasiyana yenzvimbo dzakasiyana dzetiweki, tinokugamuchirai kuuya kuzodzidza zvakawanda.
