EIGRP Feasibility Condition

Problem:

R1 has both a successor and a Feasible successor for R3 L3 (3.3.3.0/27) and R2 L2 (2.2.2.0/24)

But, when looking at the EIGRP Topology Table for R2 and R3, there isn't a Feasible successor for R3 L3 (3.3.3.0) nor for R2 L2 (2.2.2.0) - what's the deal?!

It's probably due to the feasibility condition

BGP RIB-failure

So, you’re following along in a lab configuring BGP and your “show ip bgp” reveals a RIB-failure…
