Troubleshooting IPv6
Application
Unable to Ping a Remote
Destination
Symptom
Unable to ping a remote destination and return an error message.
Solution
■ Check that the IPv6 addresses are configured correctly.
■ Use the display ipv6 interface command to determine the interfaces of the
source and the destination and the link-layer protocol between them are up.
■ Use the display ipv6 route-table command to verify that the destination is
reachable.
■ Use the ping ipv6 -t timeout { destination-ipv6-address | hostname } [ -i
interface-type interface-number ] command to increase the timeout time limit,
so as to determine whether it is due to the timeout limit is too small.
