No EIGRP neighbor on Layer 3 port

[nguyenvinnie]

After "switchport" was removed on the 6509 Gig 1/1 port, I then assign an IP address to it as well as the other end of the cable which is an 2821 router to use it as a Layer 3 ports. I can Ping across the interfaces but they can't establish EIGRP neighbor. Any ideas what I am doing wrong?

Is the new IP address included in the eigrp process ?

Can we see the show ip eigrp int output from both devices ?

Did you add your network statement for the link under the eigrp process.

Thanks for quick responds from you and EdisonOrtiz that point me to the right direction .

I had a bad mask in EIGRP statement, things are looking great now.
