@Pr1meSuspec7,

Thank you for reaching out. Unfortunately, we do not support Version 15.6(1)T of the device. Our supported versions include 17.x and above. Could you please check if the issue persists with a 17.x version and let us know? We’d be happy to assist further based on that.

Hi @roverflow, thanks for your reply. I just tested on CSR1000v with version software 17.3 and the error persists, but I found the problem:

The issue is in this section of module cisco.ios.ios_vrf:

for want_mdt in want["address_family"]:
    afi = want_mdt["afi"]
    af_dict = {}
    data_dict = want_mdt["mdt"].pop("data", {})        # <-- this is the guilty

This section tries to make a "pop" of "data" key in the "mtd" dictonary and if you don't define the "mtd" and "data" dictonary in the ansible task you get the error mentioned in this issue.

I solved the task execution by defining “mtd” and “date” in the playbook task:

    - name: Configure a vrf named management
      cisco.ios.ios_vrf:
        name: RED
        description: RED VRF
        address_family:
          - afi: ipv4
            mdt:    # <-- insert mdt without value
              data:   # <-- insert data without value
        interfaces:
          - GigabitEthernet4

In this case the playbook works:

PLAY [CONFIGURING VRF] *************************************************************************************************************************************************************************************************

TASK [Configure a vrf named management] ********************************************************************************************************************************************************************************
changed: [CSR1]

PLAY RECAP *************************************************************************************************************************************************************************************************************
CSR1                       : ok=1    changed=1    unreachable=0    failed=0    skipped=0    rescued=0    ignored=0  

But we don't have the expected result:

CSR1000v#show run vrf RED
Building configuration...

Current configuration : 169 bytes
vrf definition RED
 description RED VRF
!
!                           <- address-family missing
!
interface GigabitEthernet4
 vrf forwarding RED
 no ip address
 shutdown

 no mop enabled

end

Thanks a lot Marco

yes, I have the same problem

  tasks:
    - name: Configure VRF
      cisco.ios.ios_vrf:
        address_family:
          - afi: ipv4
        name: CUST-A
        description: VRF CUST-A
        rd: 1:100

        state: present

This task produce this error

fatal: [device.com]: FAILED! => {
    "changed": false,
    "module_stderr": "'NoneType' object has no attribute 'pop'",
    "module_stdout": "",
    "msg": "MODULE FAILURE\nSee stdout/stderr for the exact error"
}

The right configuration should be:

vrf definition CUST-A
 description VRF CUST-A
 rd 1:100
 !
 address-family ipv4
 exit-address-family

I can see what is a difference. NX-OS has module which deals with address-families

• VRF Module
• VRF AF Module
