Configuration procedure
1. Enable IPv6 forwarding on each switch and configure the IPv6 address and prefix length for each
interface as per Figure 109 . (Details not shown.)
2. Configure OSPFv3 on the switches in the IPv6 PIM-DM domain to ensure network-layer
reachability among them. (Details not shown.)
3. Enable IPv6 multicast routing, and enable IPv6 PIM-DM and MLD:
# Enable IPv6 multicast routing on Switch A, enable IPv6 PIM-DM on each interface, and enable
MLD on VLAN-interface 100, which connects Switch A to N1.
