The nROSE Configuration Guide IP Multicast Volume introduces the related content of IP multicast configuration, including multicast public configuration, IGMP, PIM-DM, PIM-SM, PIM sparse-dense, MSDP, IGMP-Snooping, etc.
The manual provides an overview of multicast technologies supported by the nROSE solution, covering both IPv4 and IPv6 environments. It describes the concepts, address structures, and routing protocols needed to deploy multicast across a network.
Key sections include detailed configuration guidance for IGMP, PIM‑DM, PIM‑SM, sparse‑dense PIM, MSDP, IGMP‑Snooping, MLD, and MLD‑Snooping, as well as tables of reserved multicast address ranges and MAC address mapping rules. This manual is written in Chinese.
| Reserved IPv4 multicast address range | 224.0.0.0‑224.0.0.255 |
|---|---|
| Multicast MAC address prefix | 0x01‑00‑5E |
The reserved IPv4 multicast range is 224.0.0.0‑224.0.0.255.
The lower 23 bits of the IP address are mapped to the lower 23 bits of a MAC address with the prefix 0x01‑00‑5E.
The manual covers MLD, IPv6 PIM, and IPv6 MLD‑Snooping configurations.
IGMP manages group membership between hosts and routers to enable multicast traffic delivery.
