用python检查{ "network_scenarios": "sdn", "vlan_planes": [ ], "vxlan_planes": [ { "network_type": "DATAPLANE", "name": "default", "vlan_id": None, "vni_start": 10000, "vni_end": 20000, "svlan_start": "", "svlan_end": "", "vdp_vlan_id": "", "mirror_svlan_start": "", "mirror_svlan_end": "", "mirror_vdp_pkt_vlan": "", "segmentation_type": "vxlan", "ip_ranges": [ { "cidr": "166.166.16.0/24", "gateway": "166.166.16.1", "start": "166.166.16.10", "end": "166.166.16.166", "vlan_id": "" } ] } ], "geneve_planes": [] }中的cidr是否配置？cidr格式是否正确？cidr是否在start和end之间？

可以使用以下Python代码来检查cidr是否配置、格式是否正确以及是否在start和end之间：

import ipaddress

data = {
    "network_scenarios": "sdn",
    "vlan_planes": [],
    "vxlan_planes": [
        {
            "network_type": "DATAPLANE",
            "name": "default",
            "vlan_id": None,
            "vni_start": 10000,
            "vni_end": 20000,
            "svlan_start": "",
            "svlan_end": "",
            "vdp_vlan_id": "",
            "mirror_svlan_start": "",
            "mirror_svlan_end": "",
            "mirror_vdp_pkt_vlan": "",
            "segmentation_type": "vxlan",
            "ip_ranges": [
                {
                    "cidr": "166.166.16.0/24",
                    "gateway": "166.166.16.1",
                    "start": "166.166.16.10",
                    "end": "166.166.16.166",
                    "vlan_id": ""
                }
            ]
        }
    ],
    "geneve_planes": []
}

cidr = data["vxlan_planes"][0]["ip_ranges"][0]["cidr"]
start = data["vxlan_planes"][0]["ip_ranges"][0]["start"]
end = data["vxlan_planes"][0]["ip_ranges"][0]["end"]

# Check if cidr is configured
if cidr:
    # Check if cidr format is correct
    try:
        ipaddress.IPv4Network(cidr)
    except ValueError:
        print("Error: cidr format is incorrect")
    else:
        # Check if cidr is within start and end range
        if ipaddress.IPv4Address(start) <= ipaddress.IPv4Address(cidr.split('/')[0]) <= ipaddress.IPv4Address(end):
            print("cidr is configured and within start and end range")
        else:
            print("Error: cidr is not within start and end range")
else:
    print("Error: cidr is not configured")

这段代码会输出 "cidr is configured and within start and end range"，表示cidr已经配置且在start和end之间。
