Protocols And Standards; Configuring Basic Functions Of Mld; Prerequisites; Enabling Mld - HP A6600 Configuration Manual

If no configuration is performed in interface view, the global configuration in MLD view will apply to that
interface. Configurations performed in interface view take precedence over those performed in MLD
view.

Protocols and standards

• RFC 2710, Multicast Listener Discovery (MLD) for IPv6
• RFC 3810, Multicast Listener Discovery Version 2 (MLDv2) for IPv6
• RFC 4605, Internet Group Management Protocol (IGMP)/Multicast Listener Discovery (MLD)-Based
Multicast Forwarding ("IGMP/MLD Proxying")

Configuring basic functions of MLD

Prerequisites

Before configuring the basic functions of MLD, 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 IPv6 PIM-DM or IPv6 PIM-SM
• Determine the MLD version
• Determine the IPv6 multicast group address and IPv6 multicast source address for static group
member configuration
Determine the ACL rule for IPv6 multicast group filtering
•
Determine the maximum number of IPv6 multicast groups that an interface can join
•

Enabling MLD

Enable MLD on the interface on which IPv6 multicast group memberships are to be created and
maintained.
To do...
1. Enter system view.
2. Enable IPv6 multicast
routing.
3. Enter interface view.
4. Enable MLD.
For more information about the multicast ipv6 routing-enable command, see IP Multicast Command
Reference.

Configuring the MLD version

Because MLD message types and formats vary with MLD versions, the same MLD version should be
configured for all routers on the same subnet before MLD can work properly.
Use the command...
system-view
multicast ipv6 routing-enable
interface interface-type interface-number
mld enable
