MLD Configuration on Huawei Routers
In this lesson we will give an example topology consist of Huawei switches and multicast hosts and then we will configure MLD on these devices.
For our example, we will use the below topology:
Let’s configure MLD on the Switch 1.
Enabling IPv6 Multicast
Firstly, we will enalble IPv6 Multicast globally on the switch.
We will use PIM-SM with MLD. So, we will enable IPv6 PIM-SM.
We will enable MLD under the interface that we will use MLD with “mld enable” command.Before this, we will enalbe Layer 3 on switch with “undo portswitch”. We will do this configuration on each interface that we will use MLD.
MLD Version Configuration
As we discussed before, MLD has twı versions; MLDv1 and MLDv2. We will set the version MLDv2 here. We will do this configuration on each interface that run MLD.
Static Group Configuration
With Static Group configuration, we can set a statically assigned group with also its specific source.
As we discussed before SSM mapping is required to use SSM with MLDv1. Without this mapping MLDv1 can not use Source Specific Multicast property. Firstly, we will enable SSM mapping, then we will set one map entry.
There are various timers used in MLD. The common ones can be configured like below. These can be configured globally and under the interface.
Saving The Configuration
To save our configuration, we will use “commit” command.
To verify our MLD configuration, we will use the below commands:
Clearing MLD Information
To reset MLD multicast group entries we can use the below commands:
• reset mld group all
• reset mld group interface
To reset SSM mapping entries, we can use the below commads:
• reset mld group ssm-mapping all
• reset mld group ssm-mapping interface interface
