Disable exporting Type 7 link-state advertisements into not-so-stubby-areas (NSSAs) for an autonomous system boundary router (ASBR) or an area border router (ABR).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:
