MLD SSM mapping configuration example
Network requirements
As shown in
•
OSPFv3 runs on the network.
•
The IPv6 PIM-SM domain uses both the ASM model and SSM model for IPv6 multicast
delivery. VLAN-interface 104 of Router D acts as the C-BSR and C-RP. The SSM group range is
FF3E::/64.
•
MLDv2 runs on VLAN-interface 400 of Router D. The receiver host runs MLDv1, and does not
support MLDv2. The receiver host cannot specify IPv6 multicast sources in its membership
reports.
•
Source 1, Source 2, and Source 3 send IPv6 multicast packets to multicast groups in IPv6 SSM
group range FF3E::/64.
Configure the MLD SSM mapping feature on Switch D so that the receiver host will receive IPv6
multicast data only from Source 1 and Source 3.

Configuration procedure
1.
Assign an IPv6 address and prefix length to each interface, as shown in
. (Details not
shown.)
2.
Configure OSPFv3 on the switches in the IPv6 PIM-SM domain. (Details not shown.)
3.
Enable IPv6 multicast routing, and enable IPv6 PIM-SM and MLD:
