Example PIM-SSM Configuration

Router R1 Configuration

On this router:

• Enable PIM-SSM with the default group range
• Configure VLAN 2 with the source host IP address 171.1.1.1/24, and enable PIM-SM on the interface
• Configure VLAN 5 with the receiver IP address 171.1.2.1/24, and enable PIM-SM on the interface
• Enable IGMP version 3 on VLAN 2 and VLAN 5. IGMP is used to determine host group membership on directly attached subnets. PIM-SSM requires IGMP version 3. Note that IGMP version 2 is enabled by default in switch mode on S- K- and 7100-Series routers.
• Enable IGMP querying on the receiver interface (VLAN 5)
