Hi Bill,
Thanks for sharing with us on this problem. I encountered a similar problem
while configuring NSSA. Sat there for 1 hr just to find out what's wrong.
Then I recalled that someone discussed this b4 in the study group. Yes,
rebooting the router is the solution.
While enabling the debug command at the NSSA ASBR when there is a problem,
I realised that the NSSA ASBR generates both a Type 5 LSA as well as a Type
7 LSA.
After I have rebooted the router, only Type 7 LSA is generated which should
be the correct behavior.
BTW, I am using 11.2(18) enterprise.
