if I add the command in /etc/quagga/ospfd.conf the changes are not inmediately applied so a service restart is needed. When I restart the service with /etc/init.d/quagga restart (or reload), all the changes in configuration are lost. Therefore, I can not test the configuration.
By the other hand, I have tested the same configuration with other different manufacturer devices and is working without any problem.
The case is, what is the point on permitting non-broadcast and point-to-multipoint OSPF configurations if you can not define its neighbors?
Thanks in advance.
