Richard,
I've never had problems with subints and EIGRP, at least not on
frame relay. EIGRP seems to treat the subints as individual interfaces. I
know in the docs they said significant changes were made back in X version
(can't remember what it was). But the 12.0 I've been using seems fine. 'Sh
ip ei int' shows all the individual subints.

Subject: Re: eigrp with secondary ip
Eigrp does not understand the concept of multiple IPs or subinterfaces, the
problem that occurs is that it will not transmit out received routes out the
same interface , (it only understands global interfaces). You need to
disable ip eigrp split horizon on the interface, then filter advertised
local routes so no loops can form. It also is helpful to make the interface
passive and then use your neighbor statements.
