Hi Guys,

hope someone can guide me here!

i succesfully get facts from one of my network devices

ansible\_facts:  
interfaces\_ip:  
GigabitEthernet0/0/0/2.1004:  
ipv4:  
172.24.70.157:  
prefix\_length: 30  
GigabitEthernet0/0/0/2.1031:  
ipv4:  
10.255.72.253:  
prefix\_length: 30

[…]

i’ve played with some of the example given here \> [http://docs.ansible.com/ansible/playbooks\_loops.html](http://docs.ansible.com/ansible/playbooks_loops.html) but without success

how can i get the interface [3rd level] linked to an IP adress [5th level] i already know (from host\_vars)

thanks in advance!

\ Francois

Not pretty, but something like this should work if the IP is only shown once in the facts:

&nbsp;&nbsp;&nbsp;- debug: msg="Interface for {{ item.value.ipv4.keys().0 }} is {{ item.key }}"  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;when: item.value.ipv4.keys().0 == '10.255.72.253'  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;with\_dict: '{{ ansible\_facts.interfaces\_ip }}'
