dhcp6relay - DHCPv6 relay agent
dhcp6relay [-Ddf] [-b boundaddr] [-H hoplim] [-r relay-IF]
[-s serveraddr] [-S script-file] [-p pid-file] interface ...
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.
Specifies the source address to relay packets to servers (or
Specifies the hop limit of DHCPv6 Solicit messages forwarded to
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.
Specifies the DHCPv6 server address to relay packets to. If not
specified, packets are relayed to ff05::1:3 (All DHCPv6 servers).
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)
Use pid-file to dump the process ID of dhcp6relay.
/var/run/dhcp6relay.pid is the default file that contains pid of the
currently running dhcp6relay.
