Release Information

Statement introduced in JUNOS Release 10.2.

Description

Configure the maximum number of link-state advertisements (LSAs) that are not generated by the router in a given OSPF instance.

Default

By default, OSPF database protection is not enabled.

Options

ignore-count number—Configure the number of times the database can enter the ignore state. When the ignore count is exceeded, the database will enter the isolate state.

Range: 1 through 32
Default: 5

ignore-time seconds—Configure the time the database must remain in the ignore state before it resumes regular operations (enters retry state).

Range: 30 through 3,600 seconds
Default: 300 seconds

maximum-lsa number—It is mandatory to configure the maximum number of LSAs whose advertising router ID is different from the local router ID in a given OSPF instance. This includes external LSAs as well as LSAs with any scope, such as the link, area, and autonomous system (AS).

Range: 1 through 1,000,000
Default: None

reset-time seconds—Configure the time period during which the database must operate without being in the ignore or isolate state before it is reset to a normal operating state.

Range: 60 through 86,400 seconds
Default: 600 seconds

warning-only—Configure that only a warning will be issued when the maximum LSA number is exceeded. If configured, no other action will be taken against the database.

warning-threshold percent—Configure the percent of the maximum number of LSAs to be exceeded before a warning message is logged.

Range: 30 through 100 percent
Default: 75 percent
