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.
