IPv6 must be enabled on both the router and the interfaces to properly function. This is crucial for routing IPv6 traffic and for interfaces to send or receive IPv6 packets.
The question is whether IPv6 needs to be enabled on the router and the interfaces using it in order to work. The answer is true. In order for IPv6 to function correctly, it must be enabled both on the router and on each of the interfaces that will be utilizing IPv6. Without enabling IPv6 on the router, the router will not be able to route IPv6 traffic. Moreover, if it's not enabled on the interfaces, those interfaces will not be able to send or receive IPv6 traffic. Therefore, both steps are necessary for the proper functioning of IPv6.
Enabling IPv6 on both the router and the interfaces is essential for the deployment and operation of an IPv6 network. This is a critical step in moving away from IPv4 and accommodating the growing number of internet-enabled devices.
