+# freyanet
+
+this container allows perring multiple servers togeather with ospf creating an internetwork on any subnet
+
+## running
+
+`docker run --privileged --network host -v $PWD/config:/config g.freya.cat/freya/freyanet`
+
+or with docker-compose:
+
+```yml
+version: "3"
+services:
+  inet2:
+	image: g.freya.cat/freya/freyanet
+	network_mode: host # needed otherwise internal network wont be accessable
+	privileged: true
+	volumes:
+	  - ./config:/config
+```
+
+## config
+
+create a file at /config/inet2.conf
+
+```
+# specify router id
+RouterID 10.1.1.1
+
+# specify routed subnets
+Subnet 10.0.0.0/8
+Subnet fd:cafe::/48
+
+# optional global private key gets used for all interfaces
+PrivateKey = {host private key}
+
+interface interfacename
+	# indentation is a single tab per level
+
+	# set the address(es) to assign to the interface
+	# route lines are usually the same as Address but with host bits zeroed
+	Address 10.2.255.1/30 
+  Route 10.2.255.0/30   # must specify route
+  # you can also set ipv6 
+  Address fd:cafe::ffff/64
+  Address fd:cafe::/64
+	# link local is also possible (and prefered for peering routers)
+	# link-local addresses should *not* have an associated Route line
+  Address fe80::1/64
+	Route 1.1.1.0/24
+	# more syntax options
+	Route 1.1.2.0/24 via 1.1.1.2
+	Route default via 1.1.1.3
+	# optional: set Gateway and Gateway6 to configure a default gateway
+	# through this interface
+	Gateway 1.1.1.2
+	Gateway6 fe80::1111:1111:1111:1111
+	# port to listen on in the host's network namespace, over udp
+	# you probably have to allow this through your firewall
+	ListenPort {host port}
+	# omit if using global private key
+	PrivateKey {host private key}
+	# all optional
+	PreUp command
+	PostUp command
+	PreDown command
+	PostDown command

+	# if running ospf on this interface
+	OSPF
+	# if running ospf on this interface and it's a stub network (no other routers)
+	OSPF stub
+	
+	peer peername
+		PublicKey {peer public key}
+		# if the peer is a router, it has to have AllowedIPs set to everything and be the only
+		# peer on the interface
+		AllowedIPs 0.0.0.0/0, ::/0
+		# either:
+		Domain = {domain name of peer}
+		Port = {peer port}
+		# or:
+		Endpoint = {peer ip}:{peer port}
+		# make domain enpoint resolve with ipv (ipv6 is default)
+		IPv4
+		
+		# optional
+		PersistentKeepalive = 25
+
+# optionally assign static addresses to the loopback interface
+# this has its uses for making things ibgp not dependent on a specific interface being up
+Loopback 1.2.3.4
+```
+
+and other optional files:
+- `/config/setup.sh` gets run on the first run of the container with the host's networking
+- `/config/start.sh` gets run every time the container starts up with the host's networking
