# Enable IPv6 multicast routing, IPv6 PIM-DM, and MLD on Router B and Router C in the same way.
(Details not shown.)
# On Router D, enable IPv6 multicast routing and enable IPv6 PIM-DM on each interface.

[RouterD] multicast ipv6 routing-enable
[RouterD] interface gigabitethernet 2/1/1

[RouterD-GigabitEthernet2/1/1] quit
[RouterD] interface serial 3/1/0
[RouterD-Serial3/1/0] pim ipv6 dm

[RouterD] interface pos 5/1/0

4. Verify the configuration:
Use the display pim ipv6 interface command to display IPv6 PIM information on each interface.
For example:
# Display IPv6 PIM information on Router D.
[RouterD] display pim ipv6 interface

# Display IPv6 PIM neighboring relationship on Router D.
[RouterD] display pim ipv6 neighbor

Assume that Host A needs to receive information addressed to IPv6 multicast group G FF0E::101.
Once the IPv6 multicast source S 4001::100/64 sends IPv6 multicast packets to the IPv6 multicast
group G, an SPT is established through traffic flooding. Routers on the SPT path (Router A and
Router D) have their (S, G) entries. Host A sends an MLD report to Router A to join IPv6 multicast
group G, and a (*, G) entry is generated on Router A. To display the IPv6 PIM routing information
on a router, use the display pim ipv6 routing-table command. For example:
# Display IPv6 PIM multicast routing table information on Router A.
[RouterA] display pim ipv6 routing-table
