Router R1 lists the following output from a show command. Which of the following is true
about R1?
R1# show ipv6 interface f0/0
FastEthernet0/0 is up, line protocol is up
IPv6 is enabled, link-local address is FE80::213:19FF:FE12:3456
No Virtual link-local address(es):
Global unicast address(es):
2000::4:213:19FF:FE12:3456, subnet is 2000:0:0:4::/64 [EUI]
Joined group address(es):
FF02::1
FF02::2
FF02::1:FF:12:3456

A.
R1’s solicited node multicast address is FF02::1:FF:12:3456.

B.
R1’s 2000::4:213:19FF:FE12:3456 address is a global unicast with all 128 bits statically
configured.

C.
Address FF02::2 is R1’s solicited node multicast.

D.
R1’s solicited node multicast, not listed in this output, would be
FF02::213:19FF:FE12:3456.

Explanation:
The group addresses listed in the output are the all IPv6 hosts address (FF02::1), the all
IPv6 routers address (FF02::2), and the solicited node address that is based on R1’s global
unicast address (FF02::1:FF:12:3456). Also, R1’s global unicast address is listed correctly in
answer B, but the “[EUI]” notation implies that R1 derived the interface ID portion using EUI-
64 conventions.
