Hi Suresh, You don't.
When I wrote the answer to that question I tried to cover both situations: one being where students use "ip ospf area" to advertise their networks and one where they redistribute. If you used the "ip ospf area" command a regular stub area would be fine. This is noted in the proctor guide too. R7 is an ASBR - it has interfaces in Area 0 and Area 78 (as noted in task 3.3 where you configure it's Ethernet interface in Area 0).

It gives reference to TASK 5.4 for that in which it is said that all the ASBRS should be able to redistribute with other routing protocols. However, in this LAB neigther router R8 or R7 is configured as ASBR and are not running any other routing protocol. In that case a regular STUB area will do. Why do we need to configure NSSA? Thanks Suresh
