Re: Cisco 837 adsl router troubleshooting

Code:

vpdn-group pppoe

protocol pppoe
!
interface ATM0
pvc8/35
encapsulation aal5snap
!

Bez aal5snap ce mozda i da prodje, ali bez vpdn-a tesko

P.S. salji end-loopback atm ping, seg takodje (kod nas) ne prolazi.

Kucao sam ovo

Code:
Router>en
Password:
Router#conf t
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#vpdn enable
Router(config)#vpdn-group pppoe
Router(config-vpdn)#re
Router(config-vpdn)#request-dialin
Router(config-vpdn-req-in)#protocol pppoe
Router(config-vpdn-req-in)#exit
Router(config-vpdn)#exit
Router(config)#int atm0
Router(config-if)#pvc 8/35
Router(config-if-atm-vc)#encapsulation aal5snap
Router(config-if-atm-vc)#end
Router#

Isti djavo :-).

Pokusavao sam ja i ranije sa vpdn, ali sam procitao da je posle verzije 12.2.(13) i kasnije pppoe klijent funkcionalnost odvojena od vpdn funkcionalnosti, pa se drugacije konfigurise, kao sto je to ovde slucaj.

Edit: Probao sam i da promenim extended ping kao sto si rekao i opet nece.

Jel' možeš da pinguješ IP adresu druge strane PPP linka?

Router(config)#access-list 101 permit icmp any any
Router(config)#end
Router#debug ip packet 101

Takođe, debug pppoe events ako ne radi ono iznad. (mislim da je events, pišem napamet...)

Inače, da bi pingovao google.com, moraš da definišeš name server, a čini mi se da ga nemaš definisanog...

Jest, nisam odmah ni primetio da je 12.4...

Sta kaze za sh pppoe session?

A i, ko sto rece Marko, dodaj neki dns server

Ovaj ping nije imao mnogo srece, obicno je 100% procenat uspesnosti, ali mi output nije zbrisao :-)

Hm, zar ne bi trebalo agregacioni ruter (druga strana dialer-a) da zna gde je DNS server?
Sad cu probati da stavim neki od ovih servera da vidim sta se desava
