We have a use-case where we want to deploy multiple BIRD instances on the same machine. The BIRD instance would be a part of public applications with their own (virtual) addreesses. These BIRD instances shall announce the application addresses (only) but not
set any local routes.</div>

A problem is that BIRD requires that a server port is opened (default 179). While the port is configurable the port numbers must be different for all applications which is hard to do (to assign each application a port is ... undesirable).</div>

Another alternative is to have a central BIRD instance and invent some way for applications to communicate their addresses. While this is certainly doable it adds an unwanted complexity, especially for testing.</div>

I would like an option to not open the server-port.</div>

As an alternative I disabled the check for setting the server port to 0 (any). It is a tiny code change and removes the coordination problem. BIRD will open an ephemeral server port which is of course useless, but we can take the waste of ports.</div>
