ciao ragazzi!
ho appena iniziato a configurare 2 2611
ho configurato le 2 ethernet, le interfacce sono up, da console mi fa il ping su entrambe,
ma dalla prima ethernet non riesco a fare ping sulla seconda ethernet…dove sbaglio???
sulle ethernet ho collegato 2 computer,

grazie!!

Router#

Da vedere così a me non sovviene nessun errore o dimenticanza.
O è così macroscopica da non farci nemmeno caso o a uno dei 2 pc mancano le impostazioni corrette di ritorno dei pacchetti.
Se configuri gli indirizzi dei PC a mano (con i parametri corretti e coerenti per la rete su cui sono connessi) cosa ti dicono ?

Lo sh int del 26 cosa ti dice ?

anche a me sembra strano, però dal caso console pinga su tutte le 2 interfacce..
PC <-> eth0/0 - eth=0/1 <-> PC

possono essere i cavi ethernet?? ho provato sia con i dritti che cross...

grazie!!

"ip routing" quando e' diventato default? 12.0 e' vecchio, ma non penso sia
cosi' vecchio da non avere "ip routing" come default. magari mi sbaglio.

se digiti "show protocols" cosa ottieni?

Speriamo:

Global values:
Internet Protocol routing is enabled

fra l'altro

Azzz... vuoi dire ?!?
Non ci avevo nemmeno pensato, ormai lo dò troppo per scontato.

Se non e' attivo ip routing mi sembra difficile che sia possibile attivare rip e ospf.

Per la cronaca, sui prodotti extreme "ipforwarding" non e' attivo per default.

I PC hanno, ovviamente, i router come gateway?

se fai traceroute dai PC cosa vedi?

hanno windows firewall che blocca i ping in entrata?

GRAZIE ragazzi!!

il problema era il dhcp server che non mi dava l'indirizzo corretto del gateway sul pc

grazie ancora!!
buona serata!!
