ISC DHCPv6 Option Configuration
DHCPv6 option values can be defined on a global or scoped basis to influence the configuration parameters of devices initializing via DHCP. Within the relevant scope the option is declared using the following general syntax which is equivalent to that for DHCP for IPv4:
option option-name option-value;
where:
- option is the keyword indicating that an option is specified on this line.
- option-name is the name of the option according to the server
- option-value is the actual value of the option to provide to the client.
The following table summarizes the DHCPv6 options currently supported (as of DHCPD 4.2.2) along with the corresponding ISC DHCP option-name and option-value data type. The Tag and Name columns in the table provide a cross reference to the Internet standard option definitions.
