The negotiated traffic selector of CHILD_SA that transports IPv6 multicast traffic must include the following address ranges:
an address range for MLDv2 traffic
an address range for multicast source (IPv6 global unicast address)
an address range for expected multicast group
The following is an example of a traffic selector of a CHILD_SA that only carries multicast traffic:
TSi
FF02::1/128 # destination address of the MLDv2 generic query packet
FE80::/64 # IPv6 link local address range, source address of the MLDv2 report packet
FF3E::/32 # IPv6 multicast address range, global scope. This is for multicast data traffic and MLDv2 (S,G) specific query
TSr
multicast source address range (global unicast)
FF02::16/128 # destination address of the MLDv2 report packet
FE80::/64 #source address of the MLDv2 query packet
