This worked for me for a specific bridge domain that had multiple subnets.
I created a loop to loop over the lists and map the subnet attribute.
The results looked like this
tasks:
- name: gather info on a subnet
aci_bd_subnet:
host: 192.168.1.1
username: admin
password: "{{password}}"
tenant: AciTest5
bd: bd-test5
state: query
validate_certs: no
delegate_to: localhost
register: results
- name: print results
debug:
msg: "{{item}}"
*loop: "{{results.current[0].fvBD.children[:] |
map(attribute='fvSubnet.attributes.rn') | list }}"*
TASK [print results]
**********************************************************************************************************************************
ok: [192.168.1.1] => (item=subnet-[10.55.2.1/24]) => {
"msg": "subnet-[10.55.2.1/24]"
}
ok: [192.168.1.1] => (item=subnet-[10.56.2.1/24]) => {
"msg": "subnet-[10.56.2.1/24]"
}
ok: [192.168.1.1] => (item=subnet-[10.57.2.1/24]) => {
"msg": "subnet-[10.57.2.1/24]"
}
