Hi, [snip] > Presently the setting for rip is: > > router rip > version 2 > passive-interface [[FastEthernet]]0/0 > network aaa.bbb.ccc.0 > no auto-summary is that aaa.bbb.ccc.0 a *public* IP class? if it is with the conf below: > router rip > version 2 > passive-interface [[FastEthernet]]0/0 > network aaa.bbb.ccc.0 > network 192.168.0.0 > network 10.0.0.0 > no auto-summary you inject private addresses to the other (public?) router... if aaa.bbb.ccc.0 is another *private* class the configuration should be ok... maybe i misunderstood your question ... cheers -- ------------------------------------------------ Daniele Santi .o. daniele at santi.vr.it ..o () ascii ribbon campaign Linux User #415108 ooo /\ www.asciiribbon.org ------------------------------------------------
