On R3, you can add a summary route: int fa 0/0# (Or whatever interface it is) ip summary-address EIGRP 100 20.0.0.0 255.0.0.0
Or you can do: ip default-network 20.0.0.0 ___ If you have multiple default networks and only want one on R1 you can: Router EIGRP 100 default-information allowed in <acl> HTHs a little!
