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.

Examples

In the first example, the command is run manually at the netsh interface ipv6 context of a command prompt. The IPv6 configuration is displayed in the command prompt window, and can be copied and pasted into a text file.

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

Displays the state of the 6to4 service.

Syntax

show state

reset

Resets the 6to4 service.

Syntax

reset

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
show 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.
