when you use a NSSA not so stubby area then the ASBR will generate N2 for
external into the area.
E2 is for external routes and will be generated by ASBR.
in a router that have under his process an Area type NSSA will convert the
Type 7 LSA to Type 5 when going from NSSA to the Backbone Area.
there are no election for ABR or ASBR, if your router have under his process
more then one area then he is ABR, if he have redistribution (or originating
a default route) then he is ASBR.
