EIGRP distribute-list

To suppress networks from being advertised in updates, use the distribute-list out command in address family or router configuration mode.

- Before the distribute-list

R2# sh ip route eigrp

     10.0.0.0/24 is subnetted, 3 subnets
D       10.8.0.0 [90/156160] via 10.12.0.1, 00:00:46, FastEthernet0/0
D       10.7.0.0 [90/156160] via 10.12.0.1, 00:00:46, FastEthernet0/0

+ After distribute-list out be applied

R2# debug ip eigrp
