[Kea-users] i do not understand the concept of shared networks

[Satish Patel]

This what i did, I have 2 subnet on VLAN100 (sharing same vlan) and i
have specified both subnet inside shared-networks, I believe you have
to do the same for all 50+ subnets.

"shared-networks": [
        {
            "name": "Public-networks",
            "interface": "ens256",
        "subnet4": [
          {
             "subnet": "172.16.102.0/23",
                "id": 100,
                "pools": [
                        {
                        "pool": "172.16.102.15 - 172.16.103.127"
                        }
                ],
                        "option-data": [
                        {
                        "name": "routers",
                        "data": "172.16.102.1"
                        },
                        {
                        "name": "domain-name-servers",
                        "data": "10.0.0.10, 10.0.0.11"
                        },
                        {
                        "name": "domain-name",
                        "data": "pub1.example.net"
                        }
                ]
          },
          {
           "subnet": "172.16.106.0/24",
            "id": 101,
            "pools": [
                {
                    "pool": "172.16.106.15 - 172.16.106.127"
                }
             ],
            "option-data": [
                {
                    "name": "routers",
                    "data": "172.16.106.1"
                },
                {
                   "name": "domain-name-servers",
                    "data": "10.0.0.10, 10.00.0.11"
                },
                {
                    "name": "domain-name",
                    "data": "foo.example.net"
                }
            ]
         }
       ]
      // You can add more subnets there (put comma on last bracket)
     } ] // end of shared-networks
