I currently reading Routing TCP/IP by Jeff Doyle. I decided to configure a mock version of his NSSA lab. I noticed that when I chanage the araea to an NSSA it stops receiving type-5 routes and does not recieve a defulat from the ABR. My normal default router is an IBGP peer which should not change. The only external routes that are advertised are those that originated on the ABR. Routes redistributed from BGP for example are lost. My question is this. Is there any way to permit these routes to enter the NSSA without doing anything drastic?
