isis-mocker

Tool provides an ability to load ISIS protocol(RFC 1195) database in json format to a lab router and emulate the whole ISIS network for the router under test(DUT). ONLY L2 P2P adjacency supported and Linux OS.

Features supported

  • P2P
  • all database content is replicated, depending on DUT config all features can work

Encoded params

Tool uses the following parameters as encoded:

  • MAC address: 00:0c:29:6f:14:bf

Installation and run

Get .deb package, install using pkg manager. Help menu can be used to get commands descriptions:

 - mock <xxxx.xxxx.xxxx>
	remove sys-id from lsdb
 - mocker <x xxxx.xxxx.xxxx ethx xx.xx.xx.xx xx.xxxx>
	start mocker instance
 - flood <x>
	start flood
 - test <x(id) x(msec 50 ... 5000)>
	start test
 - isis-mocker

Simple example how to run:

isis-mocker> run mock 0000.0000.0003       
isis-mocker> run mocker 0 0000.0000.0001 eth3 10.0.0.1 49.0001
isis-mocker> run mocker 1 0000.0000.0002 eth4 10.1.0.1 49.0001
isis-mocker> run flood 0
isis-mocker> run flood 1

0003 - is router being mocked, so DUT is placed on its position in topology 0001,0002 - neighbors of 0003 with interface on which to start mocker,ip, area then 2 instances of flood start to load isis database to DUT

Sample outputs

DUT config example:

set protocols isis level 1 disable
set protocols isis level 2 wide-metrics-only
set protocols isis backup-spf-options use-source-packet-routing
set protocols mpls interface all
