Clearing OSPF information
Syntax: database-overflow-interval <value>
The <value> can be from 0 – 86400 seconds. The default is 0 seconds.
Specifying the types of OSPF Syslog messages to log
You can specify which kinds of OSPF-related Syslog messages are logged. By default, the only
OSPF messages that are logged are those indicating possible system errors. If you want other
kinds of OSPF messages to be logged, you can configure the device to log them.
For example, to specify that all OSPF-related Syslog messages be logged, enter the following
commands.
TurboIron(config)#router ospf
TurboIron(config-ospf-router)#log all
Syntax: [no] log all | adjacency | bad_packet [checksum] | database | memory | retransmit
The log command has the following options:
The all option causes all OSPF-related Syslog messages to be logged. If you later disable this
option with the no log all command, the OSPF logging options return to their default settings.
The adjacency option logs essential OSPF neighbor state changes, especially on error cases. This
option is disabled by default.
The bad_packet checksum option logs all OSPF packets that have checksum errors. This option is
enabled by default.
The bad_packet option logs all other bad OSPF packets. This option is disabled by default.
The database option logs OSPF LSA-related information. This option is disabled by default.
The memory option logs abnormal OSPF memory usage. This option is enabled by default.
The retransmit option logs OSPF retransmission activities. This option is disabled by default.
Clearing OSPF information
The following kinds of OSPF information can be cleared from a OSPF link state database and OSPF
routing table:
• Routes received from OSPF neighbors. You can clear routes from all OSPF neighbors, or an
individual OSPF neighbor, specified either by the neighbor IP address or its router ID
• OSPF topology information, including all routes in the OSPF routing table
• All routes in the OSPF routing table that were redistributed from other protocols
• OSPF area information, including routes received from OSPF neighbors within an area, as well
as routes imported into the area. You can clear area information for all OSPF areas, or for a
specified OSPF area
The OSPF information is cleared dynamically when you enter the command; you do not need to
remove statements from the configuration or reload the software for the change to take effect.
Clearing OSPF neighbor information
To clear information on the device about all OSPF neighbors, enter the following command.
