Mismatched OSPF Timers


The default settings for the Hello and Dead timers typically work just fine. However, it is important to note that a mismatch on either setting causes two potential neighbors to never become neighbors, never reaching the two-way state. The most common way to see the current settings is to use the "show ip ospf interface" command.
