Hi Dillon,

Take a look at the EIGRP commands on the doc cd at this link:

http://www.cisco.com/univercd/cc/td/doc/product/software/ios122/122cgcr/fiprrp_r/1rfeigrp.htm#wp1031837

this specifically states the use of the neighbor statement under EIGRP and
the effects of using passive-interface with EIGRP. I believe this is the
difference that Scott may have been talking about (the difference in using
passive-interface with EIGRP, compared to the other routing protocols).

If I'm incorrect, then Scott can clarify further. :-)

HTH,

Chuck
