[quagga-users 14618] nssa, external routes from bgp, problem

Hello!


I run quite old version of quagga -  version 0.99.24.1 , from centos7 ,

but looks like there are no changes in ospf in newer versions....


I have following scheme:


area0 <->quagga<->area2<->cisco-router<->bgp.


I need to advertise routes from bgp to ospf, so I have:

redistribute bgp ...

on cisco,


but I don't need any routes from my ospf on cisco router,

although I can have these routes on cisco right now.

I decided make area2 nssa , so any ospf routes, including external, will 
not be on cisco router.

It worked OK for several days, but then , at weekend, there was 
connectivity loss on bgp side and

today I found that there are no routes from bgp in area 0, although they 
are in area 2.

Unfortunately, I had no time to read manuals and debug, so I just removed

area 2 nssa .


I guess that when bgp routes were lost and appeared again, for some 
reason LSA7 was not converted by quagga to LSA5.


Could you tell me how to solve this problem?


Thank you!
