On page 721, the Solicited-Note Multicast address is defined as FF02:0000:0000:0000:0000:0001:FF__:____,
with the last six digits being the "Last 6 Hex Digits of Unicast Address".
So why does Fig. 31-4 show PC2 with IPv6 Address of 2001:DB8:1111:1::22/64, with MAC Address 0200:2222:2222 having a Solicited-Note Multicast address of FF02::1:FF00:22?
Shouldn't the Solicited-Node Multicast address be FF02::1:FF22:2222?
This information is difficult enough to understand without inconsistencies. :(

Hi there,
You observation is correct, FF02::1:FF22:2222/104 is the correct address.

The error does not appear in the currentl published errata:

...you should make a submission, clearly everyone else who has read this chapter was suffering IPv6 fatigue and didn't notice it!
cheers,
