EIGRP & no auto-summary

J2tehk

Here is my lab.

PC1---->Router1=S0/0====S0/0=Router2<----PC2

I am running EIRGP and have a discontiguous network.

PC's are in a 10.1.0.0/24 network
Router Serial 0/0 are in a 192.168.2.148/30 network

Problem: I cannot get PC1 to ping to PC2.

My configs below:
hostname R1
!
!
ip subnet-zero
!
!
no ip domain-lookup
!
ip dhcp pool fccu2
network 10.1.1.0 255.255.255.0

end

Since you have no auto-summary, eigrp will support discontiguous networks so there is no need for nat.Also since you are natting the 10.x.x.x network you dont need to advertise it in eigrp.
The problem you have is with your access-list,change it to
access-list 10 permit 10.1.0.0 0.0.255.255

Thanks! That took care of the problem.
