ConfigExtractor

Used to emulate some cisco comand pipe outputs, currently:

• exclude
• include
• section

Details

Reads configurations in from named files (additional sources planned) and converts to a ConfigList object

ConfigList objects have a number of functions emulating Cisco behaviour:

• ConfigList.exclude()
• ConfigList.include()
• ConfigList.section()

All above functions return ConfigList objects so functions are able to be chained as show in the examples below.

Examples

From the included cisco.config show config lines that begin with interface, but not serial interfaces

from ConfExtractor.ConfExtractor import  ConfExtractor

c = ConfExtractor()
c.fromFile('cisco.config')
print (c.section(r'^iinterface').exclude(r'[Cc]ellular'))

Based on the below bgp congfiguration, return the non static redistributions from vrf cust1

from ConfExtractor.ConfExtractor import  ConfExtractor

    config = '''
