Hi

Could you compare output of 'show ospf state' and 'show ospf lsadb' between the routers that compute the external routes correctly and ones that does not?

Also, in your original post the 'show route' output from the problematic OSPF does not contain not only external routes, but also 10.10.0.0/22:

> 10.10.0.0/22         unicast [backbone 02:07:46.207] I (150/10) [c.d.143.113]

There were some changes between 2.0.5, but they were supposed to be limited to NSSA (type 7) routes.

What exactly is your topology? You seem to use NBMA, do you have fully consistent set of neighbors on all eligible routers?
