Consistency is achieved by: • Limiting the number of external LSAs in the database of each router • Ensuring that all routers have identical LSAs To configure OSPF database overflow, use the following command: configure ospf ase-limit {timeout } Where: • -Specifies the number of external LSAs that the system supports before it goes into overflow state. A limit value of 0 disables the functionality. When the LSDB size limit is reached, OSPF database overflow flushes LSAs from the LSDB. OSPF database overflow flushes the same LSAs from all the routers, which maintains consistency. • timeout-Specifies the timeout, in seconds, after which the system ceases to be in overflow state. A timeout value of 0 leaves the system in overflow state until OSPF is disabled and re-enabled. Opaque LSAs Opaque LSAs are a generic OSPF mechanism used to carry auxiliary information in the OSPF database. Opaque LSAs are most commonly used to support OSPF traffic engineering. Chapter 24.
