Have a look at the EIGRP white paper from Cisso. very well written.

When you install a static route to an interface, and configure a network
statement using router eigrp, which includes the static route, EIGRP
redistributes this route as if it were a directly connected interface.

EIGRP Default Route /w ip route 0.0.0.0/0 null0 + network 0.0.0.0????

Hi Experts,

why would EIGRP inject a 0.0.0.0/0 route with this configuration? I have
always been under the impression that the "network" statement (under
EIGRP)
only enables interfaces for participation.

Is there any explanation for this?

EIGRP Default Route /w ip route 0.0.0.0/0 null0 + network 0.0.0.0

=============================

hostname AS200-1
!
interface FastEthernet0/2
 description To Router AS200-5
 ip address 10.1.3.1 255.255.255.0
!
router eigrp 200
 network 0.0.0.0
 no auto-summary
!
ip http server
no ip http secure-server
ip route 0.0.0.0 0.0.0.0 Null0

=============================

AS200-5#r | i _0\.0\.0\.0
Gateway of last resort is 10.1.3.1 to network 0.0.0.0
D* 0.0.0.0/0 [90/28160] via 10.1.3.1, 00:13:26, FastEthernet0/2

=============================

Many Thanks.
