DHCP6RELAY(8)
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.
