Hello,
thank you for your help.
I have it now setup in the following way:
~~~
"hooks-libraries": [
{
"library": "/usr/lib/x86_64-linux-gnu/kea/hooks/libdhcp_flex_option.so",
"parameters": {
"options": [
{
"name": "domain-name-servers",
"supersede": "ifelse(member('google-ns'), '8.8.8.8', '192.168.24.2')",
"csv-format": true
}
]
}
}
],
~~~
I have not found a way to access parameters from a class, but have to put the
values directly into the supersede expression.
Just to make sure, is this the intended way to do this or is there a better way
I'm not seeing?
Thank you!
