Which IPv6 multicast address is reserved for use by all PIM routers?

A.
ff02::39

B.
ff02::13

C.
ff02::d

D.
ff02::17

Explanation:
If the IPv6 Destination Address field is the multicast address ALL-PIM-ROUTERS, the IPv6 form of
the address (ff02::d) is used. These IPv6 PIM control messages are of course not transmitted

natively over the service provider’s network, but rather are encapsulated in GRE/IPv4.
