La configurazione passata da telecom non funziona... c'è da dire che sono di formazione unix e neofita su IOS. E' una configurazione punto-punto:

Ho fatto fare un reboot a tutti e due i router per vedere che fosse tutto ok... dopo un paio di ore ancora non era tornato su il collegamento... pensavo a qualche problema di configurazione e ho ricontrolla tutto... dopo un po' è ripartito tutto.

Il bridge pinga sempre, sembra che ci sia un problema sul routing e non riesco a capire il perché... l'IOS montato è c2600-ik9o3s3-mz.123-26.bin

Non riesco a capire il perché...

Bello rispondersi da solo :D

Sulle interfacce BVI1 non era stato specificato un MAC, quindi ad ogni riavvio ne veniva impostato uno diverso, corrompendo la tabella ARP dell'altro router (IOS di default fa un cache di 4 ore), per questo se riavviavo contemporaneamente i due router il link tornava su subito.

Ho semplicemente aggiunto alla configurazione i MAC alle interfacce, in questo modo se un dei due router viene ravviato la tabella ARP rimane valida.
