ARGOMENTO:

Salve,
ho difficolta' a fare il laboratorio in oggetto,
ritengo di aver configurato (sto a meta' eserizio) ospf ma non riesco a pingare tra i computer.
Qualcuno sa darmi una mano?

qui i files

Avete ualche idea, certamente sto commettendo qualche errore ma non capisco quale questo il batch dei comandi per il router 1, per gli altri router cambiano gli ip e le interfaccie
no ip domain-lookup

qui lo show ospf neighbor:

questo lo show ip route:

Ciao Roberto,

hai fatto solo un errore di digitazione quando hai configurato il gateway di PC-A. Hai scritto 19.168.1.1 invece di 192.168.1.1

grazie, me ne sono appena accorto.
