First you get the pointer to cumulative option:
OptionPtr rai = query->getOption(DHO_DHCP_AGENT_OPTIONS);

And then you get the options inside:
OptionPtr circuit_id_opt = rai->getOption(RAI_OPTION_AGENT_CIRCUIT_ID);
OptionPtr remote_id_opt = rai->getOption(RAI_OPTION_REMOTE_ID);

Hello,

We have our client identifiers in remote-id and circuit-id (and its not mac address) I am trying to find a way in the hooks we are trying to write to extract remote-id and circuit-id from the options in the package but can’t seem to find a way to reach a sub-option ?

Is there a way to extract sub-options from something like option82?
Similar to getOption for a option without sub-options?

OptionPtr option60 = query4_ptr->getOption(60);

Or do I have to take what will be in OptionPtr option82 = query4_ptr->getOption(82) and then extract it myself?

I am thinking there must be ready made variables created to retrieve for remote and circuit id like in old isc-dhcp
option agent.circuit-id

option agent.remote-id

Best regards

Alex
