Cisco.ios.ios_l3_interfaces dhcp and autoconfig parameters don’t operate as documented

SUMMARY

Cisco.ios.ios_l3_interfaces dhcp and autoconfig parameters don’t operate as documented. When using an inventory with dhcp: { enabled: false } the dhcp config of the interface does not get removed. This same behavior occurs with the autoconfig parameter. However, when running the same inventory and changing the value of the key to true both dhcp and autoconfig get added to the interface if it wasn’t previously configured on it.

STEPS TO REPRODUCE

Run the Update l3_interfaces No DHCP/Autoconfig task
Run the same task again

    - name: Update l3_interfaces
      cisco.ios.ios_l3_interfaces:
      config:
      - name: Vlan51
        ipv6:
        - address: 2001::abcd:abcd:abcd:abcd/64
          anycast: false
          autoconfig:
            default: false
            enable: false
          cga: false
          dhcp:
            enable: false
            rapid_commit: false
          eui: false
          link_local: false
      state: merged

EXPECTED RESULTS

Step #1 should not configure DHCP and Autoconfig under the interface. Step #2 should not fail

ACTUAL RESULTS

Step #1 configures DHCP and Autoconfig under the interface Step #2 will fail the task

DHCP and Autoconfig are enabled and if run again you get “msg: address format is /, got invalid format dhcp”.
