PIM snooping configuration example

Network requirements

As shown in
• OSPF runs on the network.
• Source 1 and Source 2 send multicast data to multicast groups 224.1.1.1 and 225.1.1.1,
respectively.
• Receiver 1 and Receiver 2 belong to multicast groups 224.1.1.1 and 225.1.1.1, respectively.
• Router C and Router D run IGMP on GigabitEthernet 1/0/1. Router A, Router B, Router C, and
Router D run PIM-SM.
• GigabitEthernet 1/0/2 on Router A acts as a C-BSR and a C-RP.
To make sure Switch A forwards PIM protocol packets and multicast data packets only to the routers
that are connected to receivers, perform the following tasks:
• On Switch A, configure IGMP snooping and PIM snooping.
• On all PIM routers connected to Switch A, set the maximum size of a join or prune message to
1400 bytes, which is less than the path MTU.

Remarks
A global downstream port or a global
router port is a Layer 2 aggregate
interface that acts as a downstream
port or router port.
