Mld Ssm Mapping Configuration Example - HP 4800G Series Configuration Manual

MLD SSM Mapping Configuration Example

Network requirements
The IPv6 PIM-SM domain applies both the ASM model and SSM model for IPv6 multicast delivery.
Switch D's VLAN-interface 104 serves as the C-BSR and C-RP. The SSM group range is
FF3E::/64.
MLDv2 runs on Switch D's VLAN-interface 400. The receiver host runs MLDv1, and does not
support MLDv2. Therefore, the Receiver host cannot specify expected multicast sources in its
membership reports.
Source 1, Source 2, and Source 3 send IPv6 multicast packets to multicast groups in the IPv6 SSM
group range. It is required to configure the MLD SSM mapping feature on Switch D so that the
receiver host will receive IPv6 multicast data from Source 1 and Source 3 only.

Configuration procedure
1) Enable IPv6 forwarding and configure IPv6 addresses and IPv6 unicast routing
Enable IPv6 forwarding on each switch and configure an IPv6 address and prefix length for each
interface as shown in
Configure OSPFv3 for interoperability among the switches. Ensure the network-layer interoperation on
the IPv6 PIM-SSM network and dynamic update of routing information among the switches through a
unicast routing protocol. The detailed configuration steps are omitted here.
2) Enable IPv6 multicast routing, enable IPv6 PIM-SM on each interface and enable MLD and MLD
SSM mapping on the host-side interface.
