Bio-Routing

A re-implementation of BGP, IS-IS and OSPF in go. We value respect and robustness!

GitHub Actions Codecov Go ReportCard Go Doc

Building

To build Bio-Routing binares and/or examples you need Go installed and in your $PATH. Currently the minimum supported Go version is v1.20.

To build all commands and examples, you can leverage the Makefile, if you have make installed, and run

make build

If you're only interested in one particular command/service or example, found in the cmd/ or examples/ sub-directories within this repository, enter the respective directory on a shell and run go build. You should get a binary named like the current directory, which you can run.

To build the BGP examples, this would look like

cd exmaples/bgp
go build

To build the bio-rd service binary, this would look like

cd cmd/bio-rd
go build

Run Tests

go test -v -cover ./...

Running bio-rd

bio-rd is the main binary which provides a configurable BGP speaker. It supports the following command-line parameters:

Usage of ./bio-rd:
  -bgp.listen-addr-ipv4 string
    	BGP listen address for IPv4 AFI (default "0.0.0.0:179")
  -bgp.listen-addr-ipv6 string
    	BGP listen address for IPv6 AFI (default "[::]:179")
  -config.file string
    	bio-rd config file (default "bio-rd.yml")
  -grpc_keepalive_min_time uint
    	Minimum time (seconds) for a client to wait between GRPC keepalive pings (default 1)
  -grpc_port uint
    	GRPC API server port (default 5566)
  -metrics_port uint
    	Metrics HTTP server port (default 55667)

You can find an example configuration file within in cmd/bio-rd directory.

As bio-rd needs to listen on the priviledged TCP port 179 for BGP connections, you either need to start the service as root or using sudo, e.g.

$ sudo ./bio-rd -config.file bio-rd.yml

Benchmarks

The benchmarks can be found in the bio-routing/bio-rd-benchmarks repository.
