Bug found on quagga-0.99.18-2.fc14.x86_64 and still reproducible after updating to quagga-0.99.20-2.fc14.x86_64.
Comment 1 Jiri Skala 2012-01-13 08:07:07 UTC 
I was not able to to reproduce it (quagga-0.99.20-2.fc14.x86_64). In addition the Fedora 14 end of life has been announced just before reporting:

https://lists.fedoraproject.org/pipermail/announce/2011-December/003023.html

I've tried reproducing on F16. It works fine for me too. I'm going to close the bug.

If you hit the problem on Fedora15+ again don't hesitate to reopen it.
