Troubleshooting IPv6 basics configuration
Symptom
The peer IPv6 address cannot be pinged.
Solution
• Use the display current-configuration command in any view or the display this command in system
view to verify that IPv6 is enabled.
• Use the display ipv6 interface command in any view to verify that the IPv6 address of the interface
is correct and the interface is up.
• Use the debugging ipv6 packet command in user view to enable the debugging for IPv6 packets to
help locate the cause.
