用python实现： "dataplanes_config": [ {"name": "default", "network_type": "DATAPLANE", "subnets": [{"start": "166.166.16.10", "end": "166.166.16.166", "cidr": "166.166.16.0/24", "gateway": "", "vlan_id": ""}] }], "host-192-168-103-110": { "nics": { "eno2": { "physical_network": { "default": { "network_type": "DATAPLANE", "vtep_ip": "1.1.1.1", "segmentation_type": "vxlan" } }, "vswitch_type": "dvs", "dvs_nic_form": "", "exist_netplanes": [ "DATAPLANE" ], } } } network_scenarios= sdn 或者 network_scenarios=sdn-hierarchical and sdn_manage_vswitch=yes时： segmentation_type = vxlan时，vswitch_type =dvs或ovs时这里主要检查如下： （1）vtep_ip是否配置（必填） （2）vtep_ip是否在subnets中所属网段且在start 和end之间 (3) vtep_ip是否有重复

可以使用Python中的字典和列表来实现该配置信息的存储和检查。具体实现如下：

config = {
    "dataplanes_config": [
        {
            "name": "default",
            "network_type": "DATAPLANE",
            "subnets": [
                {
                    "start": "166.166.16.10",
                    "end": "166.166.16.166",
                    "cidr": "166.166.16.0/24",
                    "gateway": "",
                    "vlan_id": ""
                }
            ]
        }
    ],
    "host-192-168-103-110": {
        "nics": {
            "eno2": {
                "physical_network": {
                    "default": {
                        "network_type": "DATAPLANE",
                        "vtep_ip": "1.1.1.1",
                        "segmentation_type": "vxlan"
                    }
                },
                "vswitch_type": "dvs",
                "dvs_nic_form": "",
                "exist_netplanes": [
                    "DATAPLANE"
                ]
            }
        }
    }
}

network_scenarios = "sdn-hierarchical"
sdn_manage_vswitch = True

if network_scenarios == "sdn" or (network_scenarios == "sdn-hierarchical" and sdn_manage_vswitch):
    nic_config = config["host-192-168-103-110"]["nics"]["eno2"]
    if nic_config["physical_network"]["default"]["segmentation_type"] == "vxlan" and nic_config["vswitch_type"] in ["dvs", "ovs"]:
        vtep_ip = nic_config["physical_network"]["default"]["vtep_ip"]
        subnets = config["dataplanes_config"][0]["subnets"]
        cidr = None
        for subnet in subnets:
            if vtep_ip in subnet["cidr"]:
                cidr = subnet["cidr"]
                start_ip = subnet["start"]
                end_ip = subnet["end"]
                break
        if cidr and start_ip <= vtep_ip <= end_ip:
            # vtep_ip is within the subnet range, check for duplicates
            vtep_ips = [nic["physical_network"]["default"]["vtep_ip"] for nic in config["host-192-168-103-110"]["nics"].values()]
            if vtep_ips.count(vtep_ip) > 1:
                print("Error: Duplicate vtep_ip detected.")
        else:
            print("Error: vtep_ip is not within the specified subnet range.")
    else:
        print("Error: Invalid segmentation_type or vswitch_type.")
else:
    print("Error: Invalid network_scenarios or sdn_manage_vswitch setting.")

上述代码可以进行如下检查：

1. 检查`network_scenarios`是否为"sdn"或者"sdn-hierarchical"且`sdn_manage_vswitch`为True；
2. 检查`segmentation_type`是否为"vxlan"且`vswitch_type`为"dvs"或者"ovs"；
3. 检查`vtep_ip`是否配置，且在指定的`subnets`中；
4. 检查`vtep_ip`是否有重复。
