Ouroboros Tutorial 02
The description of this tutorial uses a debug build.
The objective for this tutorial is to create a 2-layer network. We will add a simple 2-node unicast Layer on top of a local Layer and will ping an oping server from an oping client over this network.
Initially, this will probably sound like gibberish, especially if configuring VLANs and defining IP subnets are your bread and butter, but once the concepts of flow allocation and binding / registering names become familiar, this will all 'click'.
We recommend opening a couple of terminal windows for this tutorial.
First, we will create a local loopback network like in the previous tutorial:
$ irm ipcp bootstrap type local name local-ipcp layer local-layerNow we will creating the 2-node unicast network
To create this small unicast network, we bootstrap the first IPCP; and then enroll a second IPCP with that first IPCP. To be able to enroll, the second IPCP will need to allocate a flow to the first one (over the local Layer). To be able to allocate the flow, the first IPCP will need to be bound to a name that is registered into the local Layer. When creating layers, we will leverage Ouroboros' anycast: instead of binding the IPCP to a single name, we will bind it to two names: the first name will be unique for each IPCP, and can be used to create flows to that specific IPCP. The second name will be common for all IPCPs in the layer.
$ irm ipcp bootstrap type unicast name uni-1 layer unicast-layer
$ irm bind ipcp uni-1 name uni-1
$ irm bind ipcp uni-1 name unicast-layer
$ irm name register uni-1 layer local-layer
$ irm name register unicast-layer layer local-layer
