Configuration procedure
1) Enable IPv6 forwarding and configure IPv6 addresses and IPv6 unicast routing
Enable IPv6 forwarding on each switch and configure an IPv6 address and prefix length for each
interface as shown in Figure 12-8 . The detailed configuration steps are omitted.
Configure OSPFv3 for interoperability among the switches. Ensure the network-layer interoperation on
the IPv6 PIM-SM domain and dynamic update of routing information among the switches through an
IPv6 unicast routing protocol. The detailed configuration steps are omitted here.
2) Enable IPv6 multicast routing, enable IPv6 PIM-SM on each interface and enable MLD and MLD
SSM mapping on the host-side interface.
# Enable IPv6 multicast routing on Switch D, enable IPv6 PIM-SM on each interface, and enable MLD
(version 2) and MLD SSM mapping on VLAN-interface 400.
