Abilitare routing su PIX

[Rizio]

Ciao a tutti, dovrei usare (a scopo laboratorio) un paio di PIX (ver 8.0.4) come router per testare dei processi eigrp.
Ho già configurato l'as eigrp e infatti vedono il routing dinamico però poi non mi effettuano routing tra le varie interfacce.
Incollo la conf, qualcuno può aiutarmi ?
