AutoNetkit

AutoNetkit is a configuration engine to quickly and easily build large-scale network configurations.

Features

High-level syntax

g_ospf = anm.add_overlay("ospf")
g_ospf.add_nodes_from(g_in.routers())
g_ospf.add_edges_from(e for e in g_in.edges() if e.src.asn == e.dst.asn)

Visualization

AutoNetkit provides real-time feedback on network designs using a d3.js network rendering engine.

Installing

$ pip install autonetkit

For the visualization:

$ pip install autonetkit_vis

Using

AutoNetkit 0.9 allows for JSON input. An example JSON input is:

{
    "directed": false, "graph": [], "multigraph": false,
    "links": [
    {"dst": "r2", "dst_port": "eth0", "src": "r1", "src_port": "eth0"},

    ],

    },
    {

    {

        ]
    }
    ]
}

Examples of topology files can be found in the example directory.

$ autonetkit -f example/house.json
INFO AutoNetkit 0.9.0
INFO IPv4 allocations: Infrastructure: 10.0.0.0/8, Loopback: 192.168.0.0/22
INFO Allocating v4 Infrastructure IPs

INFO Rendering Configuration Files

This will generate Quagga configurations and Netkit topology files.:

$ tree rendered/localhost/netkit/
rendered/localhost/netkit/
├── lab.conf
├── r1_1
│   ├── etc
│   │   ├── hostname
│   │   ├── shadow
│   │   ├── ssh
