2.9 IP Multicast
2.9.1 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:
The AR100&AR120&AR150&AR160&AR200&AR1200 series routers do not support this function.
2.9.2 How Do I Restrict Unauthorized Multicast Sources Through Configuration?
To enable routers to filter multicast data packets based on the sources or source groups so that unauthorized multicast sources are restricted, run the source-policy { acl-number | acl-name acl-name } command in the protocol independent multicast (PIM) view.
