Field Reference
Table K-118 OSPF Max Prefix Mapping Dialog Box
Element Description
Process ID The OSPF process into which other routes are being redistributed. The list
contains the OSPF processes defined in the OSPF Process Page—Setup Tab,
page K-243.
Max Prefix The maximum number of prefixes (routes) that can be redistributed into the
selected OSPF process. Limiting the number of redistributed routes helps
prevent the router from being flooded by an excessive number of routes.
Threshold The percentage of the maximum prefix value that acts as a threshold for
triggering warning messages. The default is 75%.
Note This warning is triggered whether or not the Warning-Only check
box is selected.
When maximum routes
reached
The action to take when the maximum number of redistributed routes is
reached:
• Enforce Maximum Route—Prevents additional routes from being
redistributed when the defined maximum prefix value is reached. This is
the default.
• Warning Only—Issues a warning when the maximum number of routes
is reached, but does not prevent additional routes from being
redistributed.
