This is a very basic BGP implementation to let a physical server announce an IPv6 prefix to a BGP fabric.
FeBGP will most likely be used via its Rust API. But this code also includes a main function, that allows you to execute FeBGP from the CLI:
./febgp \
--asn 65000 \
--hold-time 9 \
--router-id 1.2.3.4 \
--neighbor 2001:db8::1 \
--neighbor interface:eth0
