Long time folks, was busy with a lot of projects. Hope coming year gets less busier and I get to get my hands more dirty on networks and network security. In the meantime, here is an EIGRP cheat sheet which I thought will be helpful to folks who just want a quick theory review of Cisco’s EIGRP. Though I wanted to cover a lot more in cheat sheet like EIGRP technologies, planning but it would have defeated the purpose of cheatsheet. Never mind, I am preparing a more comprehensive EIGRP guide which I might publish soon depending on the feedback received. In the meantime, You can find the cheatsheet at Slideshare and Scribd.
