Hi guys, I am struggling in getting my KEA DHCP Server to work with my VLAN Environment. I was assuming that defining a list of virtual interfaces and subnets matching those is sufficient, but it seems that the „dhcp-socket-type: raw“ is skipping the VLAN handling in the Linux kernel and thus this Information is Kind of lost… I have read a lot About Client classes, shared Networks and so on but I have not found any solution in how to get the DHCP Server to assign correct ip pools based on the VLAN. Here is my configuration:
Interfaces:
eth0 => physical interface
eth0.30 => virtual interface
eth0.50 => virtual interface
eth0.100 => virtual interface
KEA DHCP conf:
{
"Dhcp4": {
"interfaces-config": {
"interfaces": [ "eth0", "eth0.30", "eth0.50",
"eth0.100" ],
"dhcp-socket-type": "raw"
},
"control-socket": {
"socket-type": "unix",
"socket-name": "/tmp/kea4-ctrl-socket"
},
"lease-database": {
…
},
"hosts-database": {
…
},
"sanity-checks": {
"lease-checks": "fix-del"
},
"valid-lifetime": 28800,
"rebind-timer": 21600,
"subnet4": [
{
"pools": [
{
"pool":
"192.168.20.100-192.168.20.200"
}
],
"id": 1,
"subnet": "192.168.20.0/24",
"interface": "eth0",
"option-data": [
…
]
},
{
"pools": [
{
"pool":
"192.168.30.100-192.168.30.200"
}
],
"id": 30,
"subnet": "192.168.30.0/24",
"interface": "eth0.30",
"option-data": [
…
]
},
{
"pools": [
{
"pool":
"192.168.50.100-192.168.50.200"
}
],
"id": 50,
"interface" : "eth0.50",
"subnet": "192.168.50.0/24",
"option-data": [
…
]
},
{
"pools": [
{
"pool":
"192.168.100.100-192.168.100.200"
}
],
"id": 100,
"subnet": "192.168.100.0/24",
"interface": "eth0.100",
"option-data": [
…
]
}
],
"hooks-libraries": [
…
],
"loggers": [
…
]
}
}
What do I Need to do to force the DHCP Server to assign an IP address from a
subnet based on the tagged VLAN of the request?
I am using KEA DHCP Server Version 1.6.1.
Help is much appreciated!
Thanks!
