If the ping command fails, verify the address and interface index.
Ping the link-local address of another host on your link (also known as a subnet) by typing ping Address%ScopeID, where Address is the link-local address of the other host and ScopeID is the interface index for the interface from which you want to send the ping packets.
If the ping command fails, verify the link-local address of the other host and the scope ID.
