Treba da uvezem tri Cisco 2500 rutera da bi mogao dobiti zavrsnu ocjenu iz CCNA2.
Pokusavao sam ali ne ide.

Konfigurisao sam na svakom serial interface i pazio gdje mi je DCE (clockrate).
Protokol je Rip2.
Medjutim nisam uspio, ne znam gdje sam pogresio?
Nedostatak mi je i slabo znanje engleskog pa nemam puno koristi od raznih objasnjenja
na internetu.
Pokusavao sam mjenjati kablove, mjenjao DCE mjesto ali nisam nista napravio.

Zasto mi uvjek prilikom startanja javlja da su interface podignuti pa onda da su down?
Tako za svaki ruter, evo kopija sa prvog:

Nekako sam uspio poloziti sve teoretske testove u CCNA2 (sve na engleskom), samo mi je jos ovo ostalo pa zato
molim za savjet.

Hvala unaprijed

(izgleda da jos nije konfigurisan,mozda nisam snimio konfiguraciju prije restarta, ali ako sredim ova prva dva onda ce ici i treci)

Code:

Kazes da si pazio koji je DCE... Router1 je preko svog S1 interfejsa povezan na S0 Router-a 2, jel tako? Zasto onda na oba ta interfejsa imas konfigurisan clocking?

Znaci, proveri jos jednom koji interfejs je DTE, a zatim mu ukloni "clock rate"

Pozdrav.

Drugi interfejs S1 je prikopcan na treci ruter. Ranije mi je ovdje bio DTE a na trecem ruteru DCE, i nije radilo.
Zbog toga sam prebacio, pokusao da su oba DCE na jednom (srednjem) ruteru koji je povezan sa ostala dva.
Na ostala dva je DTE.
Medjutim, ne radi ni ovako ni onako..

Hajde ovde posalji output ovih komandi sa sva tri rutera:

show controller serial 0
show controller serial 1
show running-config

Takođe, pomoglo bi da nam tačno kažeš kako su ruteri povezani:

R1 S0 - Rx Sx
R1 S1 - Rx Sx
R2 S0 - Rx Sx
R2 S1 - Rx Sx
R3 S0 - Rx Sx
R3 S1 - Rx Sx

Možda je najbolje da na odgovarajuće interfejse dodaš opis (description ...)

Ponovo sam sve prespojio i provjerio sam jos jednom da su svi kablovi cvrsto prikopcani.
Na svakom ruteru imam dva serial i jedan ethernet interfejs.

Zasto nemogu da snimim postojece stanje kad odradim komandu Router#copy running-config startup-config ?
On me pita u koji fajl da dodam (ako sam dobro razumio) ja pritisnem enter, sacekam dok odradi i on javi OK.
Medjutim ako restartam ruter gubim sve, nista nije sacuvano?

Evo sa prvog Rutera.
Na serial 0 mi je prikopcan DCE kabl a drugi kraj DTE je na drugom ruteru.
Serial 1 mi nije potreban pa nije ni konfigurisan.
Podigao sam rip protokol, i "rekao" da treba da se interface 0 reklamira na drugi ruter na kojem je ip 192.168.20.1
Da nisam pogresio sa ovim ip adresama, koristio sam 10,20,30 itd adrese, 192.168.10.0 itd ?

Re: Uvezivanje 3 Cisco rutera-problem??

^{22.05.2007. u 13:47 - pre 206 meseci}

Koliko vidim, sada bi sve trebalo da bude u redu sto se tice konektivnosti na drugom sloju, ali kao i u prethodnom postu, primecuje se pogresno adresiranje serial interfejsa.

Izmeni sledeca podesavanja pa probaj da li radi...

Na ruteru 1, ostavi IP adresu i masku Serial0 interfejsa kako jeste sad. Na ruteru 2, na Serial0 interfejsu promeni IP adresu na sledeci nacin:

Code:
Router#conf t
Router(config)#int S0
Router(confg-if)#no ip address 192.168.20.1 255.255.255.0
Router(config-if)#ip address 192.168.10.2 255.255.255.0
Router(config-if)#no shutdown

Na isti nacin promeni adresu Serial0 interfejsa na ruteru 3, iz 192.168.40.1 u 192.168.30.2.

Probaj, pa javi...

Pozdrav,
Igor

Machiveli ti je dobro rekao ali evo ti malo detaljnije ( s mog gledišta )

Re: Uvezivanje 3 Cisco rutera-problem??

^{24.05.2007. u 10:19 - pre 206 meseci}

Uradio sam ovako kako mi je Ivek33 predlozio. Koristio sam i iste ip adrese jer se cesto kod njih zbunim pa onda ne ispadne dobro. Ipak cini mi se da nisam dobio identicne konfiguracije?
Kod mene je samo negdje drugaciji kabl, DTE i DCE ali to se vidi u konfiguraciji.
I dalje nemogu snimiti postojece stanje na ruteru, ako ga ugasim gubim sve.

Moram sjesti i uciti engleski pa onda posvetiti se detalnnije ruterima.
Hvala svima na pomoci.

Evo konfiguracuje rutera i tracert koji moram isto poslati da bi dobio prolaz za ovo.
Tracert prolazi, valjda je sad sve OK i mogu poslati profesoru?

Pošalji output komande "show version" sa jednog od rutera na kojem ne možeš da snimiš konfiguraciju.

P.S. Koristi "code" tagove za output sa rutera - vidi izmenjene poruke iznad.

Ovo za koristenje code, je vjerovatno tag code /code u zagradi, nisam primjetio ovdje s lijeve strane.

Vidjecu sutra da posaljem i verziju IOS-a, moze biti da je do toga.
Profesor je govorio da bi IOS trebalo instalirati.

Nego da li je sad ovo sve OK, narocito ovaj tracert, prolazi li saobracaj kako treba, mislim da li su ovi ruteri sad uvezani i mogu li poslati ovu konfiuguraciju profesoru?

Ivek_33 mozes li poslati tracert svoje konfiguracije da uporedim i vidim da li sam pogrjesio?
