IPv6 PIM snooping configuration example
Network requirements
As shown in
:
•
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 IPv6 multicast group FF1E::101, and Receiver 2 belongs to IPv6
multicast group FF2E::101.
•
Router C and Router D run MLD on GigabitEthernet 1/0/1. Router A, Router B, Router C, and
Router D run IPv6 PIM-SM.
•
GigabitEthernet 1/0/2 on Router A acts as a C-BSR and a C-RP.
Configure MLD snooping and IPv6 PIM snooping on Switch A so that Switch A forwards IPv6
multicast packets to only the routers that are interested in the multicast data.
