Why DHCP default route not learned by EIGRP neighbor?

[AlexFer]

Simplified. Two EIGRP neighbours, C3560CX-1 & C3560CX-2. Former acts has DHCP client configuration on one interface to learn own IP, Gateway and DNS server, and, I was hoping inject default route into EIGRP.

C3560CX-1#show running-config | section router
router eigrp 1
network 10.101.250.18 0.0.0.0
redistribute static
eigrp stub connected summary

C3560CX-1#show ip eigrp topology 
EIGRP-IPv4 Topology Table for AS(1)/ID(192.168.1.19)
Codes: P - Passive, A - Active, U - Update, Q - Query, R - Reply,
r - reply Status, s - sia Status

P 10.101.250.16/29, 1 successors, FD is 2816
via Connected, Vlan18
P 0.0.0.0/0, 1 successors, FD is 28160
via Rstatic (28160/0)

C3560CX-2#show running-config | section router
router eigrp 1
network 10.101.250.17 0.0.0.0
eigrp stub connected summary

C3560CX-2#show ip eigrp topology 
EIGRP-IPv4 Topology Table for AS(1)/ID(10.101.250.17)

Why is the to-be-redistributed static route in C3560CX-1 missing in C3560CX-2?

Because you have a eigrp stub connected that just allows directly connected routes to be advertised that relate to any network command out it doesnt allow redistributed routes.

Try the following:
C3560CX-1

router eigrp xx
redistribute static
eigrp stub connected redistributed

Thank you for prompt answer..

I'd like to piggyback another question - is there a

IOS/NX-OS 

command to show routes that use specified gateway or interface? (If there's more than one gateway , then

show ip route | include gw_ip 

is not useful because printout is split over multiple lines.)
