Basically the setup looks like this:
(R1)--Area100--(R3)--Area0
|
Area100
|
(R2)
R1, R2, and R3 are connected to Area100 which is a NSSA. R3 is also
connected to Area0.
R1 is configured with Area 100 nssa default-information-originate.
Both R2 and R3 see the 0.0.0.0 route in their OSPF database but only R2
actually enters the route in its routing table. R3 is not entering the route
in its routing table.
Can you explain why that is? I figured it might have something to do with R3
being connected to Area0 but I'm not sure....
Thanks
