Hi,
I perform the similar test, the secondary address at ethernet is the
cause of
no autosummary. Once you remove the secondary Ip address, the summary
route will be
show in both routers. next you create a secondary IP address with
different major
network and advertise it, you will see that it does not auto summary for
this new Ip
address

Subject: EIGRP auto summary
Hi
I created the three loopback interfaces in EIGRP running router( Router
A)
as following to see if this router can do auto-summary.
Router A:
!
interface Loopback1
ip address 172.16.1.1 255.255.255.252
no ip directed-broadcast
!
interface Loopback2
ip address 172.16.1.5 255.255.255.252
no ip directed-broadcast
!
interface Loopback3
ip address 172.16.1.9 255.255.255.252
no ip directed-broadcast
!
interface Ethernet0
ip address 172.16.10.10 255.255.255.0 secondary
ip address 192.168.1.249 255.255.255.0
no ip directed-broadcast
no ip split-horizon eigrp 1
!
router eigrp 1
redistribute connected
network 172.16.0.0
network 192.168.1.0
!
ip http server
ip classless
!
line con 0
password xxx
transport input none
stopbits 1
line vty 0 4
exec-timeout 0 0
password xxx
login
!
end
now I checked the other router (Router B) that is connected through
Ethernet
in order to see if this three loopback subnets were auto summarized.
Unfortunately No even if auto-summary was on by default.
>From router B, I was able to see each indivisual subnet entries, which
means
auto-summary is not working.
I could manually summarize these three subnet after disabling
auto-summary,
not automatically.
Do you know why?
I will appreciate your inputs.
