NAME

4     dhcp6relay — DHCPv6 relay agent
5

SYNOPSIS

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

DESCRIPTION

11     dhcp6relay acts as an intermediary to deliver DHCPv6 messages between
12     clients and servers, and is on the same link as a client.  dhcp6relay
13     needs command line arguments interface ..., which specifies the list of
14     links accommodating clients.
15
16     Options supported by dhcp6relay are:
17
18     -d      Print debugging messages.
19
20     -D      Even more debugging information is printed.
21
22     -f      Foreground mode (useful when debugging).  Although dhcp6relay
23             usually prints warning, debugging, or error messages to
24             syslog(8), it prints the messages to standard error if this
25             option is specified.
26
27     -b boundaddr
28             Specifies the source address to relay packets to servers (or
29             other agents).
30
31     -H hoplim
32             Specifies the hop limit of DHCPv6 Solicit messages forwarded to
33             servers.
34
35     -r relay-IF
36             Specifies the interface on which messages to servers are sent.
37             When omitted, the same interface as interface will be used.  When
38             multiple interface are specified, this option cannot be omitted.
39
40     -s serveraddr
41             Specifies the DHCPv6 server address to relay packets to.  If not
42             specified, packets are relayed to ff05::1:3 (All DHCPv6 servers).
43
44     -S script-file
45             Specifies the script file to be executed when dhcp6relay receives
46             a RELAY-REPLY message from a DHCPv6 server.  Further detail of
47             the script file syntax is available in dhcp6c(8)
48
49     -p pid-file
50             Use pid-file to dump the process ID of dhcp6relay.
51

FILES

53     /var/run/dhcp6relay.pid  is the default file that contains pid of the
54                              currently running dhcp6relay.
