Thank you Mohamed.
You are quite right that eigrp does not use "default-information originate"
command. Instead you redistribute a static default, or use the interface "ip
summary-add eigrp 100 0.0.0.0 0.0.0.0" command.
The command I'm struggling with is "default-information in|out acl".
Here is a scenario:
10.1.1.1 10.1.2.1 10.1.2.2
----eigrp--------(f0/0)R1(s0/0)-----------eigrp----------------(s0/0)R2----------rip----------
R1
int f0/0
ip add 10.1.1.1 255.255.255.0
int s0/0
ip add 10.1.2.1 255.255.255.0
ip summary-add eigrp 100 0.0.0.0 0.0.0.0
router eigrp 100
net 10.1.2.1 0.0.0.0
net 10.1.1.1 0.0.0.0
R2
int s0/0
ip add 10.1.2.2 255.255.255.0
router eigrp 100
net 10.1.2.2 0.0.0.0
In the above scenario R2 will accept the default route from R1. What
circumstance would require us to use the "default-information in acl"
command then?
