determine whether the destination address is on-link and can be reached directly without passing
through a router. If the address is onlink, the address is considered as the next hop. Otherwise, the
Switch determines the next-hop from the default router list or routing table. Once the next hop IP
address is known, the Switch looks into the neighbor cache to get the link-layer address and sends
the packet when the neighbor is reachable. If the Switch cannot find an entry in the neighbor cache
or the state for the neighbor is not reachable, it starts the address resolution process. This helps
reduce the number of IPv6 solicitation and advertisement messages.
Example - Enabling IPv6 on Windows XP/2003/Vista
By default, Windows XP and Windows 2003 support IPv6. This example shows you how to use the
ipv6 install command on Windows XP/2003 to enable IPv6. This also displays how to use the
ipconfig command to see auto-generated IP addresses.
C:\>ipv6 install

IPv6 is installed and enabled by default in Windows Vista. Use the ipconfig command to check
your automatic configured IPv6 address as well. You should see at least one IPv6 address available
for the interface on your computer.
Example - Enabling DHCPv6 on Windows XP
Windows XP does not support DHCPv6. If your network uses DHCPv6 for IP address assignment,
you have to additionally install a DHCPv6 client software on your Windows XP. (Note: If you use
static IP addresses or Router Advertisement for IPv6 address assignment in your network, ignore
this section.)
This example uses Dibbler as the DHCPv6 client. To enable DHCPv6 client on your computer:
Install Dibbler and select the DHCPv6 client option on your computer.
1
After the installation is complete, select Start > All Programs > Dibbler-DHCPv6 > Client
2
Install as service.
Select Start > Control Panel > Administrative Tools > Services.
