Failure Modes
If all the nodes are not working from exactly the same map, routing loops can form. (These are situations in which, in the simplest form, two neighboring nodes each think the other is the best path to a given destination. Any packet headed to that destination arriving at either node will loop between the two, hence the name. Routing loops involving more than two nodes are also possible.)
The reason is fairly simple: since each node computes its shortest-path tree and its routing table without interacting in any way with any other nodes, then if two nodes start with different maps, it is easy to have scenarios in which routing loops are created.

Famous quotes containing the words failure and/or modes:
“There is no loneliness greater than the loneliness of a failure. The failure is a stranger in his own house.”
—Eric Hoffer (1902–1983)
“Of the modes of persuasion furnished by the spoken word there are three kinds. The first kind depends on the personal character of the speaker; the second on putting the audience into a certain frame of mind; the third on the proof, provided by the words of the speech itself.”
—Aristotle (384–323 B.C.)
