It will work if, for example:
router A has 3 nets on E0, 2 of which are secondary (obviously)
Split horizon turned off on E0
router B has 1 net on the same segment with router A, and
its IP address is on the same network as Router A's primary IP for the
segment
Since router A sends ALL eigrp updates from the primary IP on the interface,
its updates will be accepted by B since it sees an update from the right
subnet. Thats how it looks to me.. there is no ip validate-update-source
command for eigrp so I have no way of knowing.

The secondary ip addresses are still not being learned by the other router
even after "no ip split-horizon"
any other idea?
Anyway thanks for the reply Albert.

I have the following situation: On a 4500 (Router A) ethernet interface I
have the following addresses:
172.18.114.1 secondary
172.18.115.1 secondary
172.18.116.1
all masks are 24 bits
On the ethernet segment another router (Router B) with address 172.18.116.50
with mask 24 bits. Both are running EIGRP and the process number is the
same. Problem: Router B has all networks from Router A except for those
declared as secondary addresses. Why is this? How can I see all secondary
addresses configured in Router A at Router B's routing table?
Thanks in advance.
