You can use the ping command to test connectivity to systems that use IPv6. To test the function of the stack, ping the local interface using the following command:
If that works, try pinging the local computer using its IPv6 address, rather than the localhost address. Use the following command to ping a link-local node:
Replace address with the link-local address of the other node. Next, try pinging a different host using the same format, replacing address with the IPv6 address of the remote node and optionally using -s to specify the source interface. See Table 15-13 for a list of additional command switches you can use with ping to test IPV6 connectivity.
