Configuration procedure

1. Assign an IPv6 address and prefix length to each interface according to Figure 52. (Details not

shown.)

2. Configure OSPFv3 on the routers in the IPv6 PIM-DM domain to make sure they are interoperable

at the network layer and routing information among the routers can be dynamically updated.

(Details not shown.)

3. Enable IPv6 multicast routing, MLD, and IPv6 PIM-DM:

# On Router A, enable IPv6 multicast routing, enable MLD on Ethernet 1/1, and enable IPv6

PIM-DM on each interface.
