dhcp6relay — DHCPv6 relay agent

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.

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

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

       -rrelay-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.

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

       -Sscript-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)

       -ppid-file
               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.

       The dhcp6relay command first appeared in WIDE/KAME IPv6 protocol stack kit.
