Network configuration

About

Python script that generates Cisco routers' startup-config files according to network intents described in a JSON file. Useful in a network where you have several autonomous systems with different relationships (customers, peers, providers), different IGP (OSPF, RIP).

Features

• BGP, OSPFv3, RIPng
• Auto IP generation following an autonomous system (AS) IP prefix
• Local preference configuration according to relationships (customer, peer or provider) with the adjacent AS
• OSPF metric configuration

Execution

python3 conf.py <intentFile> <outputDir>

Example : python3 conf.py intent.json ./output

Quick deployment in a GNS project

python3 deploy.py <confFilesDir> <projectName>

Example : python3 deploy.py output my-gns-project

Rules

Rules for the intent file :

• lp-prefix must be 112 bits (7 blocks of 16 bits)
• For each autonomous system ip-prefix must be 48 bits :: is forbidden!

To do

• IPv4
