Using GoBGP as BGP Server
We have been using a Perl based BGP script to announce some prefixes — for black hole routing, or to ban IP addresses as a result of law enforcement requests — from a database to the network. This project was the result of searching for a new BGP daemon that can be hooked into any need and that supports the L3 MPLS VPN Unicast address family. We have used osrg/gobgp (GoBGP) as a native library for the iBGP connection into our network. GoBGP can be embedded directly as a Go library, so instead of talking to a separate daemon over gRPC we drive the BGP server in-process and feed it routes straight from our database. ...
