Modifying exit overflow interval
If a database overflow condition occurs on the Brocade device, the device eliminates the condition by
removing entries that originated on the device. The exit overflow interval allows you to set how often a
device checks to see if the overflow condition has been eliminated. The default value is 0. If the
configured value of the database overflow interval is 0, then the device never leaves the database
overflow condition.
For example, to modify the exit overflow interval to 60 seconds, enter the following command.
device(config-ospf6-router)# database-overflow-interval 60
Syntax: database-overflow-interval seconds
The seconds parameter can be a value from 0 through 86400 seconds (24 hours).
To reset the exit overflow interval to its system default, enter the no form of this command.
Modifying external link state database limit
By default, the link state database can hold a maximum of 2000 entries for external (type 5) LSAs. You
can change the maximum number of entries from 500 - 8000. After changing this limit, make sure to
save the running-config file and reload the software. The change does not take effect until you reload
or reboot the software.
For example, to change the maximum number entries from the default of 2000 to 3000, enter the
following command.
device(config-ospf6-router)# external-lsdb-limit 3000
Syntax: external-lsdb-limit entries
The entries parameter can be a numerical value from 500 through 8000 seconds.
To reset the maximum number of entries to its system default, enter the no form of this command.
Setting all OSPFv3 interfaces to the passive state
You can set all the Open Shortest Path First Version 3 (OSPFv3) interfaces to the default passive
state using the default-passive-interface command. When you configure the interfaces as passive,
the interfaces drop all the OSPFv3 control packets.
To set all the OSPFv3 interfaces to passive, enter the following commands.
device# configure terminal
device(config)# ipv6 router ospf vrf A
device(config-ospf6-router-vrf-A)# default-passive-interface
Syntax: [no] default-passive-interface
Modifying OSPFv3 interface defaults
OSPFv3 has interface parameters that you can configure. For simplicity, each of these parameters
has a default value. No change to these default values is required except as needed for specific
network configurations.
You can modify the default values for the following OSPF interface parameters:
