quagga
The config files have to be in the /etc/quagga dir and have to be writeable by the quagga user (to be able to save config from the daemon’s shell).
Neither of the daemons will start till you edit the config files and rename/move them from *.conf.sample to *.conf (be careful to the uid/gid).
You have to enable explicitly the routing daemons to get started from the init script. The config file is /etc/sysconfig/quagga
If you have a working firewall, the OSPF daemon will not get working, you have to enable it in the firewall with this rule (maybe other routing daemons also have to be enabled, if you use it, but i could not find anything about that):
iptables -A INPUT -p 89 -m state --state NEW -j ACCEPT
