Appendix H. Practice for Chapter 24: Implementing IPv6 Addressing on Routers
This appendix provides practice problems for two types of addresses: unicast addresses formed with the EUI-64 feature and solicited node multicast addresses. With EUI-64, you take the 64-bit (16 hex digit) prefix and a MAC address, manipulate the MAC address into a 64-bit value, and use those 64 bits as the interface ID. Solicited node multicast addresses are formed from a standard 26 hex digit prefix, combined with the same last 6 hex digits as the unicast address.
EUI-64 and Solicited Node Multicast Problems
Table H-1 lists some practice problems. Each problem lists a prefix and a MAC address. Then, in Table H-2, record your answers for the unicast IPv6 address, assuming that EUI-64 rules are used. Also in Table H-2, list the solicited node multicast address associated with your calculated unicast address.
