Non sono un esperto ma riuscito a configurare vari apparati cisco grazie a voi e vi ringrazio.
Ora ho un problema.
Ho un router cisco 1921 con 2 interfacce hwic ADSL con attestate 2 adsl.
Ogni ADSL esce separata su una porta GE del router. Per riuscire a configurare ciò ci ho perso veramente moltissime ore per poi riuscire con VRF. Vi chiedo a tal proposito di controllare che abbia fatto correttamente. (vengono poi gestite dal firewall).
Il problema si pone con l' ADSL 1 - operatore clouditalia - profilo a 20mb
Ho chiesto il downgrade a 7 mb per vedere se risolvo. Ho vari problemi di linea, mi si disconnette molto spesso e subito si riautentica tramite pppoa. Questa ADSL è dedicata per una VPN e immaginate i problemi del caso. Vorrei escludere un problema di configurazione.
L'adsl 2 invece, una classica telecom, ha dato anche quella svariati problemi fino a quando non è stato fatto il downgrade a 7mb e si è stabilizzata. Non si è però mai disconnessa ma si verificava una perdita di pacchetti e ping molto alti.
Vi posto la config del router
