NOTE:
•
For more information about the mld-snooping and mld-snooping enable commands, see MLD
snooping commands in the
IP Multicast Command Reference.
• After you enable IPv6 PIM snooping in a VLAN, IPv6 PIM snooping works only on the member
interfaces of the VLAN.
• IPv6 PIM snooping does not work in the sub-VLANs of a multicast VLAN. For more information about
IPv6 multicast VLAN, see the chapter “IPv6 multicast VLAN configuration.”
• In a network with IPv6 PIM snooping enabled switches, configure the size of each join/prune message
no more than the path maximum transmission unit (MTU) on the PIM-enabled edge router on the
receiver side. For more information about the join/prune messages, see “IPv6 PIM configuration.”

IPv6 PIM snooping configuration example
Network requirements
As shown in Figure 76 , Source 1 and Source 2 are connected to Router A and Router B, and Receiver 1
and Receiver 2 are connected to Router C and Router D, respectively.
Source 1 sends multicast data to IPv6 multicast group FF1E::101, and Source 2 sends multicast data to
IPv6 multicast group FF2E::101. Receiver 1 belongs to multicast group FF1E::101, and Receiver 2 belongs
to multicast group FF2E::101. Router C and Router D run MLD on their interface GigabitEthernet 1/0/1.
Router A, Router B, Router C, and Router D run IPv6 PIM-SM, and interface GigabitEthernet 1/0/2 on
Router A acts as a C-BSR and C-RP.
