Troubleshooting IPv6 basics configuration

Symptom

An IPv6 address cannot be pinged.

Solution

1. Use the display ipv6 interface command in any view to verify that the IPv6 address of the

output interface is correct and the interface is up.

2. Use the debugging ipv6 packet command in user view to enable the debugging for IPv6

packets to locate the fault.
