Windows Server 2008 cung cấp các công cụ cho phép bạn cấu hình giao diện IPv6 và kiểm tra kết nối và định tuyến IPv6. Các công cụ này cũng tồn tại thực hiện và kiểm tra khả năng tương thích IPv4-IPv6. Trong Windows 7 các công cụ dòng lệnh như Ping, Ipconfig, pathping, Tracert, Netstat, và đường có đầy đủ chức năng IPv6. | Configuring IPv6 Connectivity Windows Server 2008 provides tools that let you configure IPv6 interfaces and check IPv6 connectivity and routing. Tools also exist that implement and check IPv4-to-IPv6 compatibility. In Windows 7 the standard command-line tools such as Ping Ipconfig Pathping Tracert Netstat and Route have full IPv6 functionality. For example Figure 6-22 shows the Ping command used to check a link-local IPv6 address on the Canberra computer. The IPv6 address on your computer is different. Note that if you were pinging from one host to another using link-local addresses you would also need to include the interface ID for example ping fe80 d1ff d166 7888 2fd6 12 . Interface IDs are discussed later in this lesson. Note also that this command works because you are pinging a link-local address in the same computer. To ping between computers you need to allow ICMPv6 traffic though each computer s firewall. FIGURE 6-22 Pinging an IPv6 link-local address NOTE Ping6 The Ping6 command-line tool is not supported in Windows 7. Tools specific to IPv6 are provided in the Netsh command structure. For example the netsh interface ipv6 show neighbors command shows the IPv6 interfaces of all hosts on the local subnet. You use this command in the practice later in this lesson after you have configured IPv6 connectivity on a subnet. Verifying IPv6 Configuration and Connectivity If you are troubleshooting connectivity problems or merely want to check your configuration arguably the most useful tool and certainly one of the most used is Ipconfig. If you enter ipconfig all this displays both IPv4 and IPv6 configuration. The output from this tool was shown in Figure 6-6. If you want to display the configuration of only the IPv6 interfaces on the local computer you can enter netsh interface ipv6 show address. Figure 6-23 shows the output of this command run on the Canberra computer. Note the character followed by a number after each IPv6 address. This is the interface ID which
