passive-interface will only prevent an EIGRP adjacency being formed over
this link, the link address will still be advertised.. the only way to
prevent this from happening was mentioned by Bruce earlier :

In halfway modern code (at least 12.2 and later, I think 12.1 as well)
you can use "network <network> <wildcard>" to exactly specify the
interfaces' addresses which you want to be covered by EIGRP.. works
similar to the way you setup OSPF..
