Hi Guys,

hope someone can guide me here!

i succesfully get facts from my IOS-XR PE

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

maybe json\_query will do the trick: [https://docs.ansible.com/ansible/playbooks\_filters.html#json-query-filter](https://docs.ansible.com/ansible/playbooks_filters.html#json-query-filter)
