Hi, The closest I can go is to have a default with metric-type N1, so that the metric increase like with the inter-area default route of a totally NSSA... And to filter out all the prefixes advertised to the NSSA...
router ospf 1 log-adjacency-changes area 1 nssa default-information-originate metric-type 1 area 1 filter-list prefix TotStubSim in ip prefix-list TotStubSim seq 5 deny 0.0.0.0/0 le 32 Do you really think it is possible to get a Type3 default without the no-summay keyword?
