Netsh commands for Interface IPv6
The Netsh commands for Interface IPv6 provide a command-line
tool that you can use to query and configure IPv6 interfaces,
address, caches, and routes.
In addition, the Interface IPv6 context of netsh has a subcontext for 6to4. You can use the commands in the netsh interface IPv6 6to4 context to configure or display the configuration of the 6to4 service on either a 6to4 host or a 6to4 router.
You can run these commands from the Windows Server™ 2003 family command prompt or from the command prompt for the netsh interface IPv6 context. For these commands to work at the Windows Server™ 2003 family command prompt, you must type netsh interface ipv6 before typing commands and parameters as they appear in the syntax below. There might be functional differences between netsh context commands on Windows 2000 and the Windows Server™ 2003 family.
To view help for a command at the command prompt, type CommandName/?, where CommandName is the name of the command.
For more information about netsh, see Netsh overview and Enter a netsh context .

Netsh interface IPv6 6to4
You can use the following commands in the netsh interface
IPv6 6to4 context to display the configuration of or
configure the 6to4 service on either a 6to4 host or a 6to4
router. For more information about using the 6to4 service, see
IPv6 traffic between nodes in different sites across the
Internet (6to4)
.
For more information about Netsh, see Netsh overview .
set interface
Configures the 6to4 service on an interface.
Syntax
set interface [name=] InterfaceName [[routing=]
{enabled | disabled | default}]
Parameters
[ name=] InterfaceName
Required. Specifies the name of the interface for
which you want to set 6to4 service configuration.
InterfaceName must match the name of the
interface specified in Network Connections. If
InterfaceName contains any spaces, it must be
enclosed in quotes.
[[ routing=] { enabled| disabled|
default}]
Specifies whether the forwarding of 6to4 packets
received on the interface is enabled, disabled, or
set to its default value.
Remarks
- This command enables, disables, or sets to default the routing behavior of the 6to4 service on a specified interface.
The default setting for the routing= parameter is enabled, which enables routing on private interfaces if Internet Connection Sharing (ICS) is used.
Note
- Internet Connection Sharing and Network Bridge are not included in Windows Server 2003, Web Edition; Windows Server 2003, Datacenter Edition; and the Itanium-based versions of the original release of the Windows Server 2003 operating systems.
show interface
Displays the 6to4 service routing configuration on all
interfaces, or on a specified interface.
Syntax
show interface [[name=] InterfaceName]
Parameters
[[ name=] InterfaceName]
Specifies the name of the interface for which you
want to display the 6to4 service configuration.
InterfaceName must match the name of the
interface specified in Network Connections. If
InterfaceName contains any spaces, it must be
enclosed in quotes.
Remarks
- If an interface name is not specified, the 6to4 configuration for all interfaces is displayed.
set relay
Configures the name of the 6to4 relay router for the 6to4
service. Additionally, specifies how often the name is resolved
and the state of the relay component for the 6to4 service.
Syntax
set relay [[name=] {RelayDNSName |
default}] [[state=] {enabled | disabled
| automatic | default}] [[interval=] {ResInterval
| default}]
Parameters
[[ name=] { RelayDNSName| default}]
Specifies either the fully qualified domain name
(FQDN) of a 6to4 relay router on the IPv4 Internet (RelayDNSName),
or sets the relay name to its default value of
6to4.ipv6.microsoft.com (default).
[[ state=] { enabled| disabled|
automatic| default}]
Specifies whether the state of the relay component
for the 6to4 service is enabled, disabled,
automatically enabled if a public IPv4 address is
configured, or set to its default value.
[[ interval=] { ResInterval|
default}]
Specifies how often the name of the relay router is
resolved in minutes (ResInterval) or sets the
resolution interval to its default value of 1440
minutes (default).
Remarks
- The 6to4 relay router is a router that provides an access point between the IPv4 Internet and the 6bone (the native IPv6 portion of the Internet). In order to access 6bone resources from a 6to4 router, the 6to4 router encapsulates 6to4 traffic with an IPv4 header and sends it to the IPv4 address of the 6to4 relay router. The 6to4 relay router removes the IPv4 header and forwards the traffic to the 6bone. For return traffic, the 6to4 relay router encapsulates IPv6 traffic and sends it to the 6to4 router at the 6to4 host's site.
- The default name of the 6to4 relay router is 6to4.ipv6.microsoft.com.
- The default state is automatic, which enables the forwarding of native IPv6 traffic to a relay router when a public IPv4 address is assigned to any interface.
- The default resolution interval is 1440 minutes (once each day).
show relay
Displays the relay router configuration for the 6to4 service.
Syntax
show relay
set routing
Sets both the state of routing and the inclusion of site-local
address prefixes in Router Advertisements that are sent by the
6to4 router.
Syntax
set routing [[routing=] {enabled |
disabled | automatic | default}] [[sitelocals=]
{enabled | disabled | default}]
Parameters
[[ routing=] { enabled| disabled|
automatic| default}]
Specifies whether the state of routing on a 6to4
router is enabled, disabled, automatically enabled
if Internet Connection Sharing (ICS) is enabled, or
set to its default value.
[[ sitelocals=] { enabled| disabled|
default}]
Specifies whether the advertising of site-local
address prefixes, in addition to 6to4 address
prefixes, is enabled, disabled, or set to its
default value.
Remarks
- The default setting for the routing= parameter is automatic, which enables routing on private interfaces when ICS is used.
- The default setting for the sitelocals= parameter is enabled, which enables the advertising of site-local prefixes when site-local addresses are configured on private interfaces.
Note
- Internet Connection Sharing and Network Bridge are not included in Windows Server 2003, Web Edition; Windows Server 2003, Datacenter Edition; and the Itanium-based versions of the original release of the Windows Server 2003 operating systems.
show routing
Displays the routing configuration of the 6to4 service.
Syntax
show routing
set state
Configures the state of the 6to4 service.
Syntax
set state [[state=] {enabled | disabled
| default}] [[undoonstop=] {enabled |
disabled | default}] [[6over4=] {enabled
| disabled | default}]
Parameters
[[ state=] { enabled| disabled|
default}]
Specifies whether the state of the 6to4 service is
enabled, disabled, or set to its default value.
[[ undoonstop=] { enabled| disabled|
default}]
Specifies whether the reversal of all automatic
configuration that has been performed by the 6to4
service occurs when the service stops is enabled,
disabled, or set to its default value.
Remarks
- The default setting for the state= parameter is enabled, which enables the 6to4 service.
- The default setting for the undoonstop= parameter is enabled, which reverses all automatic configuration performed by the 6to4 service when the service is stopped.
show state

Netsh interface ipv6 isatap
Intra-Site Automatic Tunnel Addressing Protocol (ISATAP) is an
address assignment and tunneling mechanism for communication
between IPv6/IPv4 nodes within an IPv4 site. It is described in
the Internet draft titled "Intra-Site Automatic Tunnel
Addressing Protocol (ISATAP)" (draft-ietf-ngtrans-isatap-00.txt).
You can use the following commands to configure the ISATAP
router.
set router
Specifies the Intra-Site Automatic Tunneling Address Protocol
(ISATAP) router information, including router name, state, and
resolution interval.
Syntax
set router [[name=]{String | default}]
[[state=]{Enabled | Disabled | Default}]
[[interval]=Integer]
Parameters
[[ name=]{ String| default}]
Specifies whether the router is named with a string.
If default is specified, the system reverts
to using the default name.
[[ state=]{ Enabled| Disabled|
Default}]
Specifies whether the ISATAP router relays packets
between subnets.
[[ interval]= Integer]
Specifies the router resolution interval, in
minutes. The default interval is 1440 (24 hours).
Examples
The following example command sets the router name to isatap,
enables the router, and sets the resolution interval to 120
minutes:
set router isatap enabled 120
show router
Displays configuration information for the ISATAP router.
Syntax
show router
Remarks
This command displays the router name, the relay state, and the
resolution interval.
