CSR Configuration steps:

=================================

! Check if service is running

en

show iox-service

! Configure Basics

conf t

hostname CSR1

interface GigabitEthernet1

no shut

ip address 10.1.1.1 255.255.255.0

exit

exit

! Enable the service

conf t

iox

exit

show iox-service

! Configure Virtual Port

conf t

interface VirtualPortGroup0

ip unnumbered GigabitEthernet1

exit

exit

! Enable the guestshell

guestshell enable VirtualPortGroup 0 guest-ip 10.1.1.2

! Access guestshell

guestshell run bash

! Add DNS information to Linux container

echo nameserver 8.8.8.8 | sudo tee —append /etc/resolv.conf

! Need to set up routing so Router knows how to route

conf t

ip route 10.1.1.2 255.255.255.255 virtualportgroup 0

ip route 0.0.0.0 0.0.0.0 10.1.1.254

ip domain-lookup

ip name-server 8.8.8.8

exit

! Check stuff on guestshell host

======================

sudo ifconfig

cat /etc/resolv.conf

!Add a user

sudo useradd david

sudo passwd david

! Install nano and Python 3

sudo yum install nano -y

! You don't need Python3 for these script examples

sudo yum install python3

=================================

Python Script:

=================================

import sys

import cli

cli.executep(‘show ip int brief’)

cli.executep(‘show ver’)
