Host A and Host C are IPv6 multicast receivers in two stub networks, N1 and N2.
VLAN-interface 105 on Switch D and VLAN-interface 102 on Switch E act as C-BSRs and C-RPs. The
C-BSR on Switch E has a higher priority. The IPv6 multicast group range to which the C-RP is designated
is FF0E::101/64. Modify the hash mask length to map a certain number of consecutive IPv6 group
addresses within the range to the two C-RPs.
MLDv1 runs between Switch A and N1 and between Switch B/Switch C and N2.

Configuration procedure
1. Enable IPv6 forwarding on each switch and configure the IPv6 address and prefix length for each
interface as per Figure 106. (Details not shown.)
2. Configure OSPFv3 on the switches in the IPv6 PIM-SM domain to make sure the switches are
interoperable at the network layer. (Details not shown.)
3. Enable IPv6 multicast routing, MLD and IPv6 PIM-SM
