about configuring protocols in their own chapters. You can run more than one instance of

Define a constant. You can use it later in every place you could use a simple integer or an IP address.
Besides, there are some predefined numeric constants based on /etc/iproute2/rt_* files.
A list of defined constants can be seen (together with other symbols) using 'show symbols' command.
<tag>router id <m/IPv4 address/</tag> Set BIRD's router ID. It's a world-wide unique identification of your router, usually one of router's IPv4 addresses. Default: in IPv4 version, the lowest IP address of a non-loopback interface. In IPv6 version, this option is mandatory.
