6to4relay(1M) System Administration Commands 6to4relay(1M)
NAME
6to4relay - administer configuration for 6to4 relay router communication
SYNOPSIS
/usr/sbin/6to4relay
/usr/sbin/6to4relay [-e] [-a addr]
/usr/sbin/6to4relay [-d]
/usr/sbin/6to4relay [-h]
DESCRIPTION
The 6to4relay command is used to configure 6to4 relay router communication. Relay router communication support is enabled by setting the
value of a variable that stores an IPv4 address within the tun module. This variable is global to all tunnels and defines the policy for
communication with relay routers. By default, the address is set to INADDR_ANY (0.0.0.0), and the kernel interprets the value to indicate
that support for relay router communication is disabled. Otherwise, support is enabled, and the specified address is used as the IPv4 des-
tination address when packets destined for native IPv6 (non-6to4) hosts are sent through the 6to4 tunnel interface. The 6to4relay command
uses a project private ioctl to set the variable.
6to4relay used without any options outputs the current, in-kernel, configuration status. Use the -a option to send packets to a specific
relay router's unicast address instead of the default anycast address. The address specified with the -a option does not specify the policy
for receiving traffic from relay routers. The source relay router on a received packet is non-deterministic, since a different relay router
may be chosen for each sending native IPv6 end-point.
Configuration changes made by using the 6to4relay are not persistent across reboot. The changes will persist in the kernel only until you
take the tunnel down
OPTIONS
The 6to4relay command supports the following options:
-a addr Use the specified address, addr.
-e Enable support for relay router. Use -a addr if it is specified. Otherwise, use the default anycast address, 192.88.99.1.
-d Disable support for the relay router.
-h Help
OPERANDS
The following operands are supported:
addr A specific relay router's unicast address. addr must be specified as a dotted decimal representation of an IPv4 address. Other-
wise, an error will occur, and the command will fail.
EXAMPLES
Example 1: Printing the In-Kernel Configuration Status
Use /usr/sbin/6to4relay without any options to print the in-kernel configuration status.
example# /usr/sbin/6to4relay
If 6to4 relay router communication is disabled, the administrator will see the following message:
6to4relay: 6to4 Relay Router communication support is disabled.
If 6to4 router communication is enabled, the user will see this message:
6to4relay: 6to4 Relay Router communication support is enabled.
IPv4 destination address of Relay Router = 192.88.99.1
EXIT STATUS
The following exit values are returned:
0 Successful completion.
>0 An error occurred.
FILES
/usr/sbin/6to4relay The default installation root

DIAGNOSTICS
The 6to4relay reports the following messages:
6to4relay: input (0.0.0.0) is not a valid IPv4 unicast address
Example:
example# 6to4relay -e -a 0.0.0.0
Description:
The address specified with the -a option must be a valid unicast address.
6to4relay: option requires an argument -a
usage:
6to4relay
6to4relay -e [-a <addr>]
6to4relay -d
6to4relay -h
Example:
example# 6to4relay -e -a
Description:
The -a option requires an argument.
usage:
6to4relay
6to4relay -e [-a <addr>]
6to4relay -d
6to4relay -h
Example:
example# 6to4relay -e -d
Description:
The options specified are not permitted. A usage message is output to the screen.
usage:
6to4relay
6to4relay -e [-a <addr>]
6to4relay -d
6to4relay -h
Example:
example# 6to4relay -a 1.2.3.4
Description:
The -e option is required in conjunction with the -a option. A usage message is output to the screen.
6to4relay: ioctl (I_STR) : Invalid argument
Example:
example# 6to4relay -e -a 239.255.255.255
