Hierarchy Level


Configure the refresh interval for all self-generated link-state advertisement (LSAs). The OSPF standard requires that every LSA be refreshed every 30 minutes. The Juniper Networks implementation refreshes LSAs every 50 minutes. By default, any LSA that is not refreshed expires after 60 minutes. By using this configuration, you can specify when self-originated LSAs are refreshed.

You can override the default behavior by globally configuring the OSPF LSA refresh interval at the [edit protocols ospf | ospf3] hierarchy level. However, if you also have OSPF flood reduction configured for a specific interface in an OSPF area at the [edit protocols ospf | ospf3 area area-id interface interface-name] hierarchy level, the flood reduction configuration takes precedence for that specific interface.
