Problem is in both cases: when bird starts and when it's reconfigured.

When bird starts log is:
<TRACE> MyOSPF: Flushing AS-external-LSA for 0.0.0.0/0
<TRACE> MyOSPF: Premature aging self originated lsa!
<TRACE> MyOSPF: Type: 0005, Id: 0.0.0.0, Rt: 172.0.0.1
<TRACE> MyOSPF: Flushing AS-external-LSA for 0.0.0.0/0
<TRACE> MyOSPF: Premature aging self originated lsa!
<TRACE> MyOSPF: Type: 0005, Id: 0.0.0.0, Rt: 172.0.0.1

I post configuration after I configure area 10 to nssa. Problem is when 
area 10 is normal area.
