Disabling NSSA Support on an ASBR ABR

When an autonomous-system boundary router (ASBR) is also an ABR with an NSSA area attached to it, a Type 7 LSA is exported into the NSSA area by default. If the ABR is attached to multiple NSSA areas, a separate Type 7 LSA is exported into each NSSA area by default.

Note: Type 7 LSAs are not exported into an NSSA if there is only one NSSA and backbone area connected to the ABR.

To disable exporting Type 7 LSAs into NSSAs, include the no-nssa-abr statement:




no-nssa-abr;

For a list of hierarchy levels at which you can include this statement, see the statement summary section for this statement.
