All you can do here is use the totally stubby knob on the ABR(s). Once the
LSA is in the area, it is mandatory that all area resident routers receive
the LSA and correctly process it. Distribute-list in simply prevents any
relevant reachability information from making it to the local routing
table, but has no effect on LSA's.
