After configuring a few other parts of my lab successfully I have now hit an issue that I believe needs a fresh pair of eyes.
Trying to bring up a simple EIGRP adjacency between 10.44.70.1 and 10.44.70.2. My Core is sending hellos to Router 2 but for some reason the router is ignoring them. Hello / Hold Time Intervals are the same for the interfaces also.
My Core Switch - 10.44.0.1
Router 1 - 10.44.70.3 (I have a successful adjacency with my Core)
Router 2 - 10.44.70.2 (Trying to setup separate adjacency to my Core) - One I have issues with
