| NOTE: When configuring passive interfaces under EIGRP, it is important to know that this needs only be applied to either side of the adjacency to prevent routing updates on that interface. In our example, specifying FastEthernet0/0.20 in R2 as passive dropped the adjacency on R1 and R2 FastEthernet0/0.20 dropping.
