IPv6 Icky EUI-64 Drill 1 – Answers
Short and icky sweet: this post lists answers for the icky EUI-64 drill 1 for #ICND2 and #CCNA. The problems require you to find the IPv6 address a host or router would use, given a prefix, MAC address, and assuming they use stateless auto-configuration. This post lists the answers.
Table 1 lists the original problems. Table 2 then lists the unicast IPv6 addresses as calculated with EUI-64, before abbreviation, with table 3 listing the same addresses in abbreviated form as requested. Table 4 then lists the solicited node multicast address just for fun. Also, for a quick review, note that the rules for creating the second half of the unicast address using SLAAC is as follows: split the MAC, insert FFFE, and invert the 7th bit. Figure 1 summarizes the process.
