STEPS TO REPRODUCE

1. Run the Interface Update Implementation playbook

---
- name: Test ansible_net_all_ipv6_addresses var
  hosts: all
  gather_facts: no
  tasks:
      - name: Set IP on interface
        cisco.nxos.nxos_l3_interfaces:
            config:
                - name: interface1
                      ipv6:
                          - address: ipv6_address
            state: merged
     - name: DEBUG v6
       debug:
           var: ansible_net_all_ipv6_addresses

EXPECTED RESULTS

ansible_net_all_ipv6_addresses should contain IPv6 addresses configured on interfaces.

ACTUAL RESULTS

@digitalfiend64 That playbook shared in this issue doesn't seem to be correct for the stated use case. Firstly, gather_facts is set to no at the play level (it wouldn't have worked anyway because the default subset if min now, which doesn't gather interface facts). Secondly, after the Set IP on interface task executes, there's no fact gathering done. So, the var being debugged in the second task will not exist. The following should work for this situation:

---
- name: Test ansible_net_all_ipv6_addresses var
  hosts: nxos
  gather_facts: false
  tasks:
    - name: Set IP on interface
      cisco.nxos.nxos_l3_interfaces:
        config:
          - name: Ethernet1/2
            ipv6:
              - address: fd5d:12c9:2201:2::1/64
        state: merged
    
    - name: Gather facts
      cisco.nxos.nxos_facts:
        gather_subset: interfaces

    - name: DEBUG v6
      debug:
        var: ansible_net_all_ipv6_addresses

Please let me know if this resolves the issue. Thanks!
