Configure multicast on the AR router

4

For the AR router, the configuration roadmap is as follows:
1. Configure the Layer 3 multicast function on the Layer 3 network to implement multicast routing (supported by some AR models).
a. Configure a unicast routing protocol to achieve unicast interworking. This is the prerequisite of multicast routing.
b. Configure PIM-SM and configure a multicast traffic aggregation point as the rendezvous point (RP).
c. Enable IGMP on interfaces of user gateways to learn multicast service requirements of users. PIM generates multicast routes based on IGMP group information and forwards multicast data to receiver network segments.
2. Configure Layer 2 multicast on the Layer 2 network to forward multicast data to Layer 2 outbound physical interfaces accurately.
a. Enable IGMP snooping in a VLAN.

Other related questions:
Can the NAT interface of the AR router be configured with multicast
Multicast can be configured on the interface where NAT is configured. NAT is only valid for unicast packets.

Is multicast enabled on the AR router by default
By default, the multicast function of the AR router is disabled.

Whether the NAT interface of AR router can be configured multicast?
Configure NAT on AR router interface can be configured multicast, but the configuration of the NAT only effect on unicast packets, multicast packets are not supported in NAT.

Which multicast protocols do AR series routers support
In earlier versions of V200R005C00, Huawei AR series routers support the following multicast protocols: - MSDP - PIM-SM - PIM-DM - IGMP - IGMP snooping and MLD snooping Note: AR150&AR200 series routers and AR1200 series routers do not support IGMP snooping or MLD snooping. In V200R005C00 and later versions, Huawei AR series routers support the following multicast protocols: MSDP - PIM-SM - PIM-SM (IPv6) - PIM-DM - PIM-DM (IPv6) - IGMP - MLD - IGMP snooping and MLD snooping Note: AR150&AR200 series routers and AR1200 series routers do not support IGMP snooping or MLD snooping.

Which multicast protocols do Huawei AR series enterprise routers support
In versions earlier than V200R005C00, the Huawei AR Series Enterprise Routers support the following multicast protocols: -Multicast Source Discovery Protocol (MSDP) -Protocol independent multicast sparse mode (PIM-SM) -Protocol independent multicast dense mode (PIM-DM) -Internet Group Management Protocol (IGMP) -IGMP Snooping and MLD Snooping NOTE: AR150&AR200 series routers and AR1200 series routers do not support IGMP Snooping and MLD Snooping. In V200R005C00 and later versions, the Huawei AR Series Enterprise Routers support the following multicast protocols: -Multicast Source Discovery Protocol (MSDP) -Protocol independent multicast sparse mode (PIM-SM) -Protocol independent multicast sparse mode (PIM-SM) for IPv6 -Protocol independent multicast dense mode (PIM-DM) -Protocol independent multicast dense mode (PIM-DM) for IPv6 -Internet Group Management Protocol (IGMP) -Multicast Listener Discovery (MLD) -IGMP Snooping and MLD Snooping NOTE: AR120&AR150&AR160&AR200&AR500 series routers, AR510 series routers and AR1200 series routers do not support IGMP Snooping and MLD Snooping.
