Configuration Prerequisites; Enabling Mld Ssm Mapping; Configuring Mld Ssm Mappings; Configuring Mld Proxying - HP 6125G Configuration Manual

Configuration prerequisites

Before you configure the MLD SSM mapping feature, complete the following tasks:
Enable IPv6 forwarding and configure an IPv6 unicast routing protocol so that all devices in the
•
domain can be interoperable at the network layer.
• Configure basic MLD functions.

Enabling MLD SSM mapping

Step
1. Enter system view.
2. Enter interface view.
3. Enable the MLD SSM
mapping feature.
NOTE:
To ensure SSM service for all hosts on a subnet, regardless of the MLD version running on the hosts, enable
MLDv2 on the interface that forwards IPv6 multicast traffic onto the subnet.

Configuring MLD SSM mappings

By performing this configuration multiple times, you can map an IPv6 multicast group to different IPv6
multicast sources.
If MLDv2 is enabled on a VLAN interface of a switch, and if a port in that VLAN is configured as a
simulated host, the simulated host will send MLDv2 reports even if you did not specify an IPv6 multicast
source when you configure simulated joining with the mld-snooping host-join command. In this case, the
corresponding IPv6 multicast group will not be created based on the configured MLD SSM mappings.
For more information about the mld-snooping host-join command, see IP Multicast Command Reference.
To configure an MLD SSM mapping:
Step
1. Enter system view.
2. Enter MLD view.
3. Configure an MLD SSM
mapping.

Configuring MLD proxying

Before you configure the MLD proxying feature, complete the following tasks:
Enable IPv6 forwarding and configure an IPv6 unicast routing protocol so that all devices in the
•
domain are interoperable at the network layer.
Enable IPv6 multicast routing.
