Yemi,
Thanks for responding. Here's an attempt at putting your explanation into a
scenario
10.1.1.1 10.1.2.1 10.1.2.2
10.1.3.1
----eigrp10------(f0/0)R1(s0/0)-----------eigrp10-------------(s0/0)R2(f0/0)---eigrp20--
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 10
net 10.1.2.1 0.0.0.0
net 10.1.1.1 0.0.0.0
R2
int f0/0
ip add 10.1.3.1 255.255.255.0
int s0/0
ip add 10.1.2.2 255.255.255.0
router eigrp 10
net 10.1.2.2 0.0.0.0
redistr eigrp 20
router eigrp 20
net 10.1.3.1 0.0.0.0
redistr eigrp 10
no default-originate out
R2 is receiving a default from R1 on process eigrp10, and redistributing to
process eigrp20. Would the use of this command as indicated then prevent R2
from sending the default into eigrp20? If yes, how do ACLs fit in?
