What is IPv6 ISATAP?

What is IPv6 ISATAP?

ISATAP is Short for Intra-Site Automatic Tunnel Addressing Protocol, ISATAP is a method of transmitting IPv6 packets on an IPv4 network that is most recently defined in RFC 5214. ISATAP works by mapping an IPv4 address into the IPv6 address and requires an ISATAP gateway on the IPv6 Internet and the IPv4 intranet.

What is ISATAP routing?

ISATAP (Intra Site Automatic Tunnel Addressing Protocol) is an IPv6 tunneling technique that allows you to connect IPv6 over an IPv4 network, similar to the automatic 6to4 tunnel. On your IPv4 network, you can configure one of your routers as an IPv6 “headend” ISATAP router that your IPv6 hosts can connect to.

How do I configure ISATAP?

Procedure

1. Configure the ISATAP router. # Enable the IPv4/IPv6 dual stack and configure an IP address for each interface.
2. Configure the ISATAP host. The ISATAP host is relevant to the operating system.
3. Configure the IPv6 host.
4. Verify the configuration.

What is Isatap home?

home is an internal network name and refers to the Microsoft ISATAP adaptor for the IPv6 protocol.

What is 6to4 and Teredo?

Unlike 6to4, where the two halves of a connection can use different relays, traffic between a native IPv6 host and a Teredo client uses the same Teredo relay, namely the one closest to the native IPv6 host network-wise. The Teredo client cannot localize a relay by itself (since it cannot send IPv6 packets by itself).

What is ISATAP adapter?

The Microsoft ISATAP device Inter Site Automatic Tunneling Address Protocol is used to help enterprises transition to an IPv6 infrastructure. The ISATAP adapter encapsulates IPv6 packets by using an IPv4 header. This functionality enables the client to transport IPv6 traffic over an IPv4 infrastructure.

How do I ping ISATAP?

# Ping the global unicast address of the tunnel interface on the ISATAP host running Windows 7 operating system from the ISATAP router. # Ping the global unicast address of the ISATAP router from the ISATAP host running Windows 7 operating system. # Ping the IPv6 host from the ISATAP host. The ping operation succeeds.

How do I change the tunnel adapter in ISATAP?

You may remove them with following steps:

1. Open Start Menu.
2. Type In: Device Manager.
3. Select Device Manager.
4. Click the View menu from the top.
5. Select Show Hidden Devices (Must be check before continuing)
6. Scroll down and expand Network Adapters.
7. Right-Click a duplicated Microsoft 6to4 Adapter or Microsoft ISATAP Adapter.

How do I disable ISATAP?

To disable ISATAP:

1. Type netsh interface isatap set state disabled and press Enter.
2. Use ipconfig to confirm that ISATAP was disabled.
3. Close the command prompt to complete this activity.

How does ISATAP work with IPv6?

How ISATAP works. ISATAP defines a method for generating a link-local IPv6 address from an IPv4 address, and a mechanism to perform Neighbor Discovery on top of IPv4. Any host wishing to participate in ISATAP over a given IPv4 network can set up a virtual IPv6 network interface.

How do I configure ISATAP host a to receive 6to4 router advertisement?

To configure ISATAP Host A to receive the router advertisement from 6to4 Router A, the network administrator for Site A has configured 6to4 Router A as an ISATAP router and added an A record to Site A’s DNS infrastructure so that the name ISATAP is resolved to the IPv4 address of 192. 168. 204. 1.

What is the IPv4 address of the ISATAP-derived interface ID?

If the host had multiple IPv4 addresses assigned, the IPv4 address used in the ISATAP-derived interface ID would be that which is the best source to reach 172.31.87.6, the IPv4 address of the ISATAP router.

Why ICMPv6 Neighbor Discovery is not available in ISATAP?

Because ISATAP uses IPv4 as a non multicast/broadcast-capable (unlike Ethernet) link layer, ICMPv6 Neighbor Discovery cannot be done in the usual manner. That is why ISATAP is a bit more complex than 6over4. From the viewpoint of the IPv6 packet, the link layer is the IPv4 packet.
