init()

void isc::dhcp::ControlledDhcpv6Srv::init

Initializes the server.

It reads the JSON file from disk or may perform any other setup operation. In particular, it also install signal handlers.

This method may throw if initialization fails.

loadConfigFile()

ConstElementPtr isc::dhcp::ControlledDhcpv6Srv::loadConfigFile

(

const std::string &

file_name

)

Configure DHCPv6 server using the configuration file specified.

This function is used to both configure the DHCP server on its startup and dynamically reconfigure the server when SIGHUP signal is received.

It fetches DHCPv6 server's configuration from the 'Dhcp6' section of the JSON configuration file.

This utility method is called whenever we know a filename of the config and need to load it. It calls config-set command once the content of the file has been loaded and verified to be a sane JSON configuration. config-set handler will process the config file (apply it as current configuration).

Parameters

file_name

name of the file to be loaded

Returns

status of the file loading and outcome of config-set

Configuration processor.

This is a method for handling incoming configuration updates. This method should be called by all configuration backends when the server is starting up or when configuration has changed.

As pointer to this method is used a callback in ASIO used in ModuleCCSession, it has to be static.

Parameters

config

textual representation of the new configuration

Returns

status of the config update
