Detailed Description

This class parses a single IPv6 subnet.

This is the IPv6 derivation of the SubnetConfigParser class and it parses the whole subnet definition. It creates parsersfor received configuration parameters as needed.

◆ Subnet6ConfigParser()

isc::dhcp::Subnet6ConfigParser::Subnet6ConfigParser ( )

Constructor.

stores global scope parameters, options, option definitions.

Member Function Documentation

◆ duplicate_option_warning()

void isc::dhcp::Subnet6ConfigParser::duplicate_option_warning	(	uint32_t	code,
		asiolink::IOAddress &	addr
	)

protectedvirtual

Issues a DHCP6 server specific warning regarding duplicate subnet options.

Parameters

code	is the numeric option code of the duplicate option
addr	is the subnet address

Todo:: A means to know the correct logger and perhaps a common message would allow this message to be emitted by the base class.

◆ initSubnet()

void isc::dhcp::Subnet6ConfigParser::initSubnet	(	isc::data::ConstElementPtr	params,
		isc::asiolink::IOAddress	addr,
		uint8_t	len
	)

protectedvirtual

Instantiates the IPv6 Subnet based on a given IPv6 address and prefix length.

Parameters

params	Data structure describing a subnet.
addr	is IPv6 prefix of the subnet.
len	is the prefix length

client-class processing is now generic and handled in the common code (see isc::data::SubnetConfigParser::createSubnet)

Implements isc::dhcp::SubnetConfigParser.

◆ parse()

Subnet6Ptr isc::dhcp::Subnet6ConfigParser::parse ( data::ConstElementPtr subnet )

Parses a single IPv6 subnet configuration and adds to the Configuration Manager.

Parameters

subnet A new subnet being configured.

Returns: a pointer to created Subnet6 object

Parse all pools first.
