Configuring Mld Ssm Mappings; Configuring Mld Proxying; Configuration Prerequisites; Enabling Mld Proxying - HP A5500 SI Switch Series Configuration Manual

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

Configuring MLD SSM mappings

You can map an IPv6 multicast group to different IPv6 multicast sources by configuring this task
repeately.
Follow these steps to configure an MLD SSM mapping:
To do...
Enter system view
Enter MLD view
Configure an MLD SSM mapping
CAUTION:
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 configuring 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 the
Reference
.

Configuring MLD proxying

Configuration prerequisites

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

Enabling MLD proxying

You can enable MLD proxying on the interface in the direction toward the root of the multicast
forwarding tree to make the device serve as an MLD proxy.
