3. Kuedza kuchinjika kune inoyangarara yakamira nzira kana nzira huru yatadza

General information

Saka, chekutanga, mazwi mashoma ekuti chii chinonzi static uye kunyange nzira inoyangarara. Kusiyana neane simba nzira, static routing inoda kuti iwe uzvimirire kuvaka nzira inoenda kune yakatarwa network. Iyo inoyangarara static nzira inoshanda kupa nzira yekuchengetedza kune yekuenda network kana yekutanga nzira ikatadza.

Tichishandisa network yedu semuenzaniso, "Border Router" kusvika parizvino ine nzira dzakabatana chete neISP1, ISP2, LAN_1 neLAN_2 network.

Kugadzira Default Basic Static Route

Tisati tataura nezve nzira yekuchengetedza, isu chekutanga tinoda kuvaka nzira huru. Rega nzira huru kubva kumucheto router iende kuburikidza neISP1 kuenda kuInternet, uye nzira kuburikidza neISP2 ichava yekuchengetedza. Kuti uite izvi, isa yakasarudzika static nzira pamupendero router mune yepasi rose gadziriso modhi:

Edge_Router>en
Edge_Router#conf t
Edge_Router(config)#ip route 0.0.0.0 0.0.0.0 s0/0/0 

kupi:

• yekutanga 32 bits ye zero ndiyo kero yetiweki yekuenda;
• yechipiri 32 bits ye zero ndeye network mask;
• s0/0/0 ndiyo inobuda interface yemupendero router, iyo yakabatana kune ISP1 network.

Izvi zvinoratidza kuti kana mapaketi anosvika kumucheto router kubva kuLAN_1 kana LAN_2 aine kero yenetiweki yekuenda isiri patafura yekufambisa, anozoendeswa mberi kuburikidza neinterface s0/0/0.

Ngatitarisei tafura yekumberi yerouta uye titumire ping kuwebhu server kubva kuPC-A kana PC-B:

Isu tinoona kuti yakasarudzika static nzira yekupinda yakawedzerwa kune routing tafura (sezvinoratidzwa neiyo S * yekupinda). Ngatitsvagei nzira kubva kuPC-A kana PC-B kuenda kuwebhu server:

Yekutanga hop inobva kuPC-B kuenda kumucheto router's local IP address 192.168.11.1. Yechipiri hop inobva kumucheto router kusvika 10.10.10.1 (ISP1). Rangarira, isu tichafananidza shanduko gare gare.

Kuisa nzira inoyangarara yakamira

Saka, iyo huru static nzira yakagadzirwa. Tevere, isu tinogadzira, chokwadi, inoyangarara static nzira kuburikidza neISP2 network. Iyo nzira yekugadzira inoyangarara static nzira haina kusiyana neyakajairwa yakamira static nzira, kunze kwekunge iyo yekutanga zvakare inotsanangura daro rekutonga. Chinhambwe chekutonga zvinoreva mwero wekuvimbika kwenzira. Chokwadi ndechekuti nhambwe yekutonga yenzira isingachinjiki yakaenzana neimwe, izvo zvinoreva kukoshesa zvachose pamusoro pezvirongwa zvemafambisirwo, ane nhambwe yekutonga yakakura zvakapetwa kazhinji, kunze kwenzira dzemunharaunda - kwavari yakaenzana ne zero. Saizvozvo, kana uchigadzira yakamira inoyangarara nzira, iwe unofanirwa kutsanangura nhambwe yekutonga yakakura kupfuura imwe, semuenzaniso, 5. Saka, iyo inoyangarara nzira haizove yakakosha pamusoro peiyo main static nzira, asi panguva yekusawanikwa kwayo, iyo yakasarudzika nzira. achatorwa semukuru.

Syntax yekutsanangura nzira inoyangarara yakamira seiyi:

Edge_Router(config)#ip route 0.0.0.0 0.0.0.0 s0/0/1 5

kupi:

• 5 kukosha kwechinhambwe chekutonga;
• s0/0/1 ndiyo inobuda interface yemupendero router yakabatana neISP2 network.

Ndinoda kutaura ipapo ipapo Ipo iyo nzira huru iri mukushanda, iyo inoyangarara static nzira haizoonekwe mutafura yekufambisa. Kuti tiwedzere kugutsikana, ngatiratidze zviri mukati metafura yekufambisa panguva iyo nzira huru iri mumamiriro akanaka:

Iwe unogona kuona kuti tafura yekufambisa ichiri kuratidza yakasarudzika main static nzira ine inobuda interface Serial0/0/0 uye hapana dzimwe nzira dzakasimba dzinoratidzwa mutafura yenzira.

Kuedza kuchinjika kune inoyangarara yakamira nzira kana nzira huru yatadza

Uye zvino chikamu chinonyanya kufadza: Ngatitevedzerei kutadza kwenzira huru. Izvi zvinogona kuitwa nekudzima iyo interface padanho resoftware, kana kungobvisa kubatana pakati peiyo router neISP1. Dzima iyo Serial0/0/0 interface yenzira huru:

Edge_Router>en
Edge_Router#conf t
Edge_Router(config)#int s0/0/0
Edge_Router(config-if)#shutdown

... uye nekukurumidza mhanya kuti utarise patafura yekufambisa:

Mumufananidzo uri pamusoro, unogona kuona kuti mushure meiyo main static nzira yakundikana, iyo yekubuda interface Serial0/0/0 yakachinja kuita Serial0/0/1. Mukutsvaga kwekutanga takamhanya kare, hop inotevera kubva kumucheto router yaive yeIP kero 10.10.10.1. Ngatienzanise shanduko nekutsvaga zvakare uchishandisa nzira yekuchengetedza:

Ikozvino shanduko kubva kumucheto router kuenda kuwebhu server iri kuburikidza neIP kero 10.10.10.5 (ISP2).

Ehe, static nzira dzinogona kuoneka nekuratidzira ikozvino router kumisikidza:

Edge_Router>en
Edge_Router#show run
