Question about Guestshell & ZTP on ISR1111 or ISR4321

[Jerems]

Hi all,

I aim to perform ZTP operations on Cisco Routers using DHCP options and Python script.

Once the router receives its DHCP lease, it should be able to execute a python script to register itself in NSO.

I found a way to activate guestshell on an ISR1111 once its booting process is over so it can launch a downloaded python script :

Router#show app-hosting list
App id State
---------------------------------------------------------
guestshell RUNNING

I would like to know how to make this guestshell container starts at the initial boot of the router and make it behaves as it was coming out from the box to let the ZTP process begins.

Thanks in advance for your help,

Jerems

I was able to perform ZTP on both router as long as i used one of the latest version of ios-xe on both platform :

ISR1111 : Version 17.06.01a

ISR4321 : Version 17.07.01a

I will indicate here what is the oldest version of IOS-XE required to perform ZTP on both platform.
