Quotes from tac about eigrp :
Q. Does EIGRP support secondary addresses?
A. EIGRP does support secondary addresses. Since EIGRP always sources data
packets from the primary address, we recommend that you configure all
routers on a particular subnet with primary addresses that belong to the
same subnet. Routers will not form EIGRP neighbors over secondary networks,
therefore, if all routers' primary IP addresses do not agree, problems can
arise with neighbor adjacencies.

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.
