OSPF default route with nssa?

[jiangyixiao]

I have the topology following as:

r1-(fr)-r2--r3--r4 (r1-r2:nssa area r2-r3:area 0 r3-r4: normal area XX)

If I want to import default route into all ospf area , how can do use most simple way? I want to config R1(asbr) import,but R2 sometimes cant't translate type 7 0.0.0.0 lsa into TYPE5 , you must use special OSPF mode on frame. who knows why ? or may be use other solution. thanks!

Actuall NSSA does not generate defulat route to OSPF domian, but configuration "area x nssa default originate" in r1 can pass out default route to ospf domain as a LSA type 7.

have you tried this ?

if resolve this, reply again.

Thanks.
