Introduction : For controller to start processing IPv6 packets at L3, it has to be globally enabled on the controller.
Feature Notes : Required for enabling and functioning of any other IPv6 functionality on the controller.
Environment : IPv6 used on controller interfaces and by clients.
Network Topology : Controller (IPv6) ======= Uplink Router (IPv6)
Configuration Steps : To enable IPv6 in the controller globally, run the below command.
(config) #ipv6 enable
Answer : Post enabling one should be able to ping IPv6 interfaces on the Controller.
Verification: (config) #show ipv6 global
Global IPv6 Packet Processing is Enabled
Troubleshooting : One should be able to ping other IPv6 devices as the subnet of the Controller.
#show ipv6 global
Global IPv6 Packet Processing is Enabled
#ping ipv6 2001::2
Press 'q' to abort.
Sending 5, 92-byte ICMPv6 Echos to 2001::2, timeout is 2 seconds:
