Hi, group:

     A question for the secondary address. The example
below take a nat for 10.10.10.0/24 and make the rip for
the secondary address. In the reference book , it said use
the rip with secondary address for broadcast rip message
into network. But I don't know the reason, if I want to
communicate with 200.200.200.0/24, the nat is enough. And
the rip hasn't revelation with 10.10.10.0/24, so I think
the rip is meanless, isn't it ?

Thanks alot
