I have a question that pertains OSPF NSSA external routes.
The topology goes as follows:
R1 area 0 <--------->area0 R2 area29 <-------->area29 R3
Area 29 is configured as nssa.
In R3 i have static routes that are being redistributed into ospf and are being seen as external routes in R1. I happen to configure a new interface in R3, mistakinly, in area 28 (suposed to be 29). The moment i did that, the external routes disapeared from R1.
why is that??
