I checked it with GNS 3:

R1#sh ip route
Codes: C – connected, S – static, R – RIP, M – mobile, B – BGP
D – EIGRP, EX – EIGRP external, O – OSPF, IA – OSPF inter area
N1 – OSPF NSSA external type 1, N2 – OSPF NSSA external type 2
E1 – OSPF external type 1, E2 – OSPF external type 2
i – IS-IS, su – IS-IS summary, L1 – IS-IS level-1, L2 – IS-IS level-2
ia – IS-IS inter area, * – candidate default, U – per-user static route
o – ODR, P – periodic downloaded static route

Gateway of last resort is not set

D 4.0.0.0/8 [90/409600] via 10.1.4.2, 00:00:17, FastEthernet0/0
10.0.0.0/24 is subnetted, 2 subnets
D 10.2.4.0 [90/307200] via 10.1.4.2, 00:02:01, FastEthernet0/0
C 10.1.4.0 is directly connected, FastEthernet0/0
R1#

Auto-Summary is on by default.
