EIGRP - Hello packets

[GeneBeamer]

I was doing some sniffing of my network and noticed that my EIGRP hello packets are being sent/seen to all my internal switches. How can i stop this? Do I just make the internal vlans a passive interface or is there another way?

Making the interfaces passive is probably the cleanest and easiest way to accomplish this.

Depending on your environment, you may want to look at using the "passive-interface default" option. So if you have many interfaces and just a few that need actual peering, it will make things a lot easier.
