Refer to the exhibit. Routers R1, R2, and R3 have IPv6 reachability, and R1 and R3 are able to ping each other with the IPv6 global unicast address.
However, R1 and R3 are unable to ping each other with their link-local addresses. What is a possible reason for the problem?
A. Link-local addresses can communicate with neighboring interfaces.
B. Link-local addresses are forwarded by IPv6 routers using loopback interfaces.
C. Link-local addresses can be used only with a physical interface’s local network.
D. Multicast must be enabled to allow link-local addresses to traverse multiple hops.
