Others have pointed several great open source BGP daemons which can interface
with Linux routing.  If you just want to ignore BGP for forwarding, and point a default
at one place, you might like to consider ExaBGP.  This is very lightweight - it can do
the BGP announcing of your prefix(es) without syncing routing changes to the Linux
routing table.  There are some simple AS112 instances, for example, delivered with
this model.  https://github.com/Exa-Networks/exabgp
