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 1 1 1 1 1 1 1 1, 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.
•
When set to 0, this address is an IPv6 multicast address without an embedded RP address.
R •
When set to 1, this address is an IPv6 multicast address with an embedded RP address.
(The P and T bits must also be set to 1.)
•
When set to 0, this address is an IPv6 multicast address not based on a unicast prefix.
P •
When set to 1, this address is an IPv6 multicast address based on a unicast prefix. (The T
bit must also be set to 1.)
•
When set to 0, this address is an IPv6 multicast address permanently-assigned by IANA.
T
•
When set to 1, this address is a transient, or dynamically assigned IPv6 multicast address.
