freyanet

peer multiple ospf nodes over wireguard to make an internal network

running

docker

version: "3"
services:
  inet2:
    image: g.freya.cat/freya/freyanet
    network_mode: host # needed otherwise internal network wont be accessable
    privileged: true
    volumes:
      - ./inet2.conf:/etc/inet2.conf

host

run the following commands with the provided makefile

$ make
$ make <os>

the current supported os's are: alpine

start the inet2 service to start freyanet

config

if running in docker mount a file called inet2.conf at /etc/inet2.conf
if running on host make a file called /etc/inet2.conf

# specify router id for ospf
RouterID 10.1.1.1

# optionally assign static addresses to the loopback interface
Loopback 1.2.3.4

# specify routed subnets
# ips that are not in these subnets will be ignored
# put the ip blocks for your entire internal network

Subnet fd:cafe::/32

# specify node stubnets

    # link local is also possible (and prefered for peering routers)
