Brain,
Correct me if I am wrong here. RIP and OSPF commands (default-information
originate) generate a default route

It allows for the sending or receiving of a default route. It does not
actually generate a default route but only permits it to be sent or
received.
In the examples below R1 is receiving a default route via EIGRP from R2.
R2 is redistributing the default route into EIGRP via static.
The first example shows R1 denying the default learned via EIGRP from R2
by using the "no default-information in" command.
Rack1R1(config-router)#do show ip route eigrp
172.16.0.0/24 is subnetted, 1 subnets
D EX 172.16.1.0 [170/258816] via 146.1.12.2, 00:00:01,
FastEthernet0/0
150.1.0.0/24 is subnetted, 1 subnets
D 150.1.2.0 [90/156160] via 146.1.12.2, 00:00:01, FastEthernet0/0
D*EX 0.0.0.0/0 [170/258816] via 146.1.12.2, 00:00:01, FastEthernet0/0
Rack1R1(config-router)#no default-information in
Rack1R1(config-router)#do clear ip route *
Rack1R1(config-router)#do show ip route eigrp
172.16.0.0/24 is subnetted, 1 subnets
D EX 172.16.1.0 [170/258816] via 146.1.12.2, 00:00:05,
FastEthernet0/0
150.1.0.0/24 is subnetted, 1 subnets
D 150.1.2.0 [90/156160] via 146.1.12.2, 00:00:05, FastEthernet0/0
Rack1R1(config-router)#
The second example shows R2 not allowing a default to be sent to R1 by
using the "no default-information out" command.
Rack1R1#show ip route eigrp
172.16.0.0/24 is subnetted, 1 subnets
D EX 172.16.1.0 [170/258816] via 146.1.12.2, 00:00:03,
FastEthernet0/0
150.1.0.0/24 is subnetted, 1 subnets
D 150.1.2.0 [90/156160] via 146.1.12.2, 00:00:03, FastEthernet0/0
D*EX 0.0.0.0/0 [170/258816] via 146.1.12.2, 00:00:03, FastEthernet0/0
