Important Considerations
■
There are three choices for memory allocation:
■
Have the module intelligently determine the maximum OSPF
memory partition size (partition size =
1
). This is the default.
■
Have OSPF be part of module memory, growing as needed and
without limit (partition size =
0
).
■
Configure the maximum OSPF memory partition size manually
(partition size =
4096
-
<maximum available memory>
).
■
You typically do not have to modify the OSPF memory allocation.
However, if the softRestarts statistic shown by the
ip ospf
statistics
option begins to climb, it means that OSPF is thrashing
for memory and you must increase the maximum memory.
For a complete description of OSPF memory allocation, see the “OSPF
Memory Partition” section in the OSPF chapter of the
Switch 4007
Implementation Guide
.
■
The partition size option that you enter takes effect after you reboot
the module.
