NAME

dhcp6relay — DHCPv6 relay agent

SYNOPSIS

dhcp6relay [-Ddf] [-b boundaddr] [-H hoplim] [-r relay-IF] [-s serveraddr] [-S script-file] [-p pid-file] interface ...

DESCRIPTION

dhcp6relay acts as an intermediary to deliver DHCPv6 messages between clients and servers, and is on the same link as a client. dhcp6relay needs command line arguments interface ..., which specifies the list of links accommodating clients.

Options supported by dhcp6relay are:

-d

Print debugging messages.

-D

Even more debugging information is printed.

-f

Foreground mode (useful when debugging). Although dhcp6relay usually prints warning, debugging, or error messages to syslog(8), it prints the messages to standard error if this option is specified.

-b boundaddr

Specifies the source address to relay packets to servers (or other agents).

-H hoplim

Specifies the hop limit of DHCPv6 Solicit messages forwarded to servers.

-r relay-IF

Specifies the interface on which messages to servers are sent. When omitted, the same interface as interface will be used. When multiple interface are specified, this option cannot be omitted.

-s serveraddr

Specifies the DHCPv6 server address to relay packets to. If not specified, packets are relayed to ff05::1:3 (All DHCPv6 servers).

-S script-file

Specifies the script file to be executed when dhcp6relay receives a RELAY-REPLY message from a DHCPv6 server. Further detail of the script file syntax is available in dhcp6c(8)

-p pid-file

Use pid-file to dump the process ID of dhcp6relay.

FILES
/var/run/dhcp6relay.pid

is the default file that contains pid of the currently running dhcp6relay.
