A fleet garage configures one side of a /30 fiber as OSPF broadcast and the other as point-to-point, and the adjacency never fully forms. What is the most accurate operational impact?
Select an answer to reveal the explanation.
Short Explanation
Broadcast expects a DR party; point-to-point expects a simple two-router handshake—and their hello timers don’t even share the same default rhythm. Mix them on a /30 and the adjacency often never settles. Match the network type on both ends.
Full Explanation
OSPF network types dictate hello/dead timers, DR/BDR behavior, and adjacency rules. A broadcast versus point-to-point mismatch on a link produces incompatible expectations and frequently blocks FULL adjacency. The mismatch is not ignored, does not morph into EIGRP, and should not be assumed to reach FULL reliably without correction.
