2. IPv6 multicast addresses
Figure 4 IPv6 multicast format
The following describes the fields of an IPv6 multicast address:
• 0xFF—The most significant eight bits are 11111111, which indicates that this address is an IPv6
multicast address.
• Flags—The Flags field contains four bits.
Figure 5 Format of the Flags field
Table 4 Description on the bits of the Flags field
Bit Description
0 Reserved, set to 0
R
• When set to 0, it indicates that this address is an IPv6 multicast
address without an embedded RP address
• 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)
