Explanation:
This router demonstrates an example of an IPv6 Dual Stack configuration.
Dual stack (Figure 1 below) runs both IPv4 and IPv6 protocol stacks on a router in parallel, making it similar to the multiprotocol network environments of the past, which often ran Internetwork Packet Exchange (IPX), AppleTalk, IP, and other protocols concurrently.
The technique of deploying IPv6 using dual-stack backbones allows IPv4 and IPv6 applications to coexist in a dual IP layer routing backbone.
The IPv4 communication uses the IPv4 protocol stack, and the IPv6 communication uses the IPv6 stack.
As a transition strategy, dual stack is ideal for campus networks with a mixture of IPv4 and IPv6 applications.
