Experimental config file.

# Yet another comment
After today's lengthy discussions about filter syntax, let's clean up whitespace/semicolon rules for whole config file: o All non-zero amounts of whitespace are equivalent to single space (aka `all the whitespace has been born equal' ;-)). o Comments count as whitespace. o Whitespace has no syntactic signifance (it can only separate lexical elements). o Consequence: line ends are no longer treated as `;'s. o Every declaration must be terminated by an explicit `;' unless or by a group enclosed in `{' and `}'.

Trivial 15-line bison excercise: Implemented expressions including user-defined numeric symbols. Whenever possible, use `expr' instead of `NUM' to get full express ion power :-)

Allow input and output filters (only accept/reject style as we didn't define modifying filters yet) to be attached to protocol instances.

Added configuration of the device internal protocol. This is primarily intended to serve as an example of interface pattern list use. As a side effect, you can disable generating of device routes by disabling this protocol.

Updated filters: they now actually see IP/pxlen of net being filtered, gateway, and who told us, so they can do usefull jobs from now on.

Moved to a much more systematic way of configuring kernel protocols. o Nothing is configured automatically. You _need_ to specify the kernel syncer in config file in order to get it started. o Syncing has been split to route syncer (protocol "Kernel") and interface syncer (protocol "Device"), device routes are generated by protocol "Direct" (now can exist in multiple instances, so that it will be possible to feed different device routes to different routing tables once multiple tables get supported). See doc/bird.conf.example for a living example of these shiny features.

Kernel syncer is now configurable. It will probably need some more options, but at least basic tuning is possible now.

Changed syntax of attaching filters to protocols to hopefully the final version: EXPORT <filter-spec> for outbound routes (i.e., those announced by BIRD to the rest of the world). IMPORT <filter-spec> for inbound routes (i.e., those imported by BIRD from the rest of the world). where <filter-spec> is one of: ALL pass all routes NONE drop all routes FILTER <name> use named filter FILTER { <filter> } use explicitly defined filter For all protocols, the default is IMPORT ALL, EXPORT NONE. This includes the kernel protocol, so that you need to add EXPORT ALL to get the previous configuration of kernel syncer (as usually, see doc/bird.conf.example for a bird.conf example :)).

# import none; # Default is import all
export all; # Default is export none
