Refer to the exhibit.
Routers R1,R2, and R3 have IPv6 reachability, and R1 and R3 are able to ping each other
with IPv6 global unicast address. However, R1 and R3 are unable to ping eachother with
their link-local address. What is a possible reason for the problem?
A.
Multicast must be enabled to allow link-local address to traverse multiple hops.
B.
Link-local addresses can be used only with a physical interface’s local network
C.
ICMPv6 packets are dropped when the destination uses a link-local address
D.
Link-local addresses are forwarded by IPv6 routers using loopback interfaces
E.
Link-local address can communicate with neighboring nodes only if routing is
enabled between them
