Yes but my point was; there are 2 ways advertize route into EIGRP
or any routing protocol
1. network STM under the routing protocol
2. Redistribute into routing protocol

Subject: RE: Little question about EIGRP summary address
Remember my earlier example?
Ip route 10.10.0.0 255.255.255.0 null0254
Router eigrp 1
Redis static metric 1 1 1 1 1
Int f0/0
Ip summary-address eigrp 1 10.0.0.0 255.0.0.0 5
Now the eigrp route entered the eigrp topology database via the
redistribution from static.
Consider this...
Router#Show ip int brief
R2#sh ip int brief
Interface IP-Address OK? Method Status
Protocol
FastEthernet0/0 173.17.180.3 YES NVRAM up
up
FastEthernet0/1 193.1.180.3 YES NVRAM up
up
Router eigrp 1
Network 10.10.0.0
Int f0/0
Ip summary-address eigrp 1 10.0.0.0 255.0.0.0 5
No interface matches the network command, so the eigrp top db does not
include 10.x.x.x anything, so the summary is not created...

Seems contratictory by your own eg
-redistribution from another protocol, including static -learned from an
eigrp neighbor -network command matching an up/up interface on the
router.

"That is not advertising the routes in eigrp". The "network" command
determines on which interfaces we run eigrp on. Using the network
command with a non-existent interface for the purpose of later
generating a summary does not work.
You can get the constituent routes for creating the summary into eigrp
via
-redistribution from another protocol, including static -learned from an
eigrp neighbor -network command matching an up/up interface on the
router.

Do you mean advertisizing those routes in Eigrp?
Eg
Router eigrp 100
Net 10.10.10.1 0.0.0.0
Net 10.10.11.1 0.0.0.0
Net 10.10.12.1 0.0.0.0
Int e0/0
Summary eigrp 10.10.0.0 0.0.255.255

When ever you need to generate a summary route, those routes need to be
advertised in the specific routing protocol before a summary is
generated.
