If you do not know the route's next hop IP address, type NETSTAT at the command line, and select option 2 (Display TCP/IP route information) to view the route information.
Verify with the network administrator that the IP address specified as the next hop is correct. If it is not correct, you need to delete the route entry, add a new route, and specify the correct next hop IP address.
For IPv4
To ping the next hop, type PING 'nnn.nnn.nnn.nnn' at the command line, where 'nnn.nnn.nnn.nnn' is the IP address for the next hop interface on the route.
For IPv6
To ping the next hop, type PING 'x:x:x:x:x:x:x:x' at the command line, where 'x:x:x:x:x:x:x:x' is the IP address for the next hop interface on the route.
