Which role is this issue related to?

cisco.nac_dc_vxlan.dtc.create

Which section of the data model is this issue related to?

vxlan.topology

Expected Behavior

Routed interfaces are configured on devices with IPv6 management addresses.

Actual Behavior

TASK [cisco.nac_dc_vxlan.create : Manage Interface Routed] ******************************************************************************************
fatal: [marehler_vnd3]: FAILED! => {"changed": false, "msg": "Error: Switches ['2001:420:448b:8006:fab2:0:0:13', '2001:420:448b:8006:fab2:0:0:23', '2001:420:448b:8006:fab2:0:0:24'] are not managable in Fabric 'VXLAN-FABRIC-2', No changes are allowed on these switches\n"}

Steps to Reproduce

Use IPv6 management addresses not using double colons. Example:

---
vxlan:
  topology:
    switches:
      - name: N9Kv-SPINE3
        role: spine
        serial_number: 940TOBQT4KY
        management:
          management_ipv6_address: 2001:420:448b:8006:fab2:0:0:13
          default_gateway_v6: 2001:420:448b:8006::1
        routing_loopback_id: 0
        interfaces:
          - name: Ethernet1/3
            mode: routed
            enabled: false
          - name: Ethernet1/4
            mode: routed
            enabled: false
          - name: Ethernet1/5
            mode: routed
            enabled: false

Relevant Debug Output

No response

Initial Analysis

• The issue is similar to TASK Add NDFC Fabric Devices <name> fails for IPv6 Devices #251. Same as cisco.dcnm.dcnm_inventory, the cisco.dcnm.dcnm_interface module does not properly handle IPv6 addresses in different representations.
• As a workaround for issue TASK Add NDFC Fabric Devices <name> fails for IPv6 Devices #251, I have changed my topology data not using double colons.
• However, while dcnm_inventory fails when using double colons, dcnm_interfaces fails when not using double colons.

Workaround

Use IPv6 addresses with double colons, e.g. 2001:420:448b:8006:fab2::13
