Referring to
Figure 1-4
, the meanings of the fields of an IPv6 multicast address are as follows:
z
0xFF: The most significant 8 bits are 11111111, indicating that this address is an IPv6 multicast
address.

Flags: Referring to
Figure 1-5
, the following table describes the four bits of the Flags field.

Description
0
Reserved, set to 0
R
z
When set to 0, it indicates that this address is an IPv6 multicast address without
an embedded RP address
z
When set to 1, it indicates that this address is an IPv6 multicast address with an
embedded RP address (The P and T bits must also be set to 1)
