MLD proxying configuration example
Network requirements
As shown in Figure 90:
IPv6 PIM-DM runs on the core network.
Host A and Host C on the stub network receive VOD information sent to IPv6 multicast group
FF3E::101.
Configure the MLD proxying feature on Router B so that Router B can maintain group memberships
and forward IPv6 multicast traffic without running IPv6 PIM-DM.
Figure 90 Network diagram
Configuration procedure
1. Assign an IPv6 address and prefix length to each interface, as shown in Figure 90. (Details not
shown.)
2. Enable IPv6 multicast routing, IPv6 PIM-DM, MLD, and MLD proxying:
# On Router A, enable IPv6 multicast routing.
<RouterA> system-view
[RouterA] ipv6 multicast routing
[RouterA-mrib6] quit
# Enable IPv6 PIM-DM on GigabitEthernet 1/0/2.
[RouterA] interface gigabitethernet 1/0/2
[RouterA-GigabitEthernet1/0/2] ipv6 pim dm
