How to do it...

1. Inside the new folder, ch3_junos, we create a hosts file with the following content:

$ cat hosts

[pe]
mxpe01 Ansible_host=172.20.1.3
mxpe02 Ansible_host=172.20.1.4

[p]
mxp01 Ansible_host=172.20.1.2
mxp02 Ansible_host=172.20.1.6

[junos]
mxpe[01:02]
mxp[01:02]
 
[core:children]
pe
p

2. Create an Ansible.cfg file, as shown in the following code:

$ cat Ansible.cfg
 
 [defaults]
 inventory=hosts
 retry_files_enabled=False
 gathering=explicit
 host_key_checking=False
