Example: Configuring an SSM-Only Domain

date_range 23-Nov-23

Deploying an SSM-only domain is much simpler than deploying an ASM domain because it only requires a few configuration steps. Enable PIM sparse mode on all interfaces by adding the mode statement at the [edit protocols pim interface all] hierarchy level. When configuring all interfaces, exclude the fxp0.0 management interface by adding the disable statement for that interface. Then configure IGMPv3 on all host-facing interfaces by adding the version statement at the [edit protocols igmp interface interface-name] hierarchy level.

In the following example, the host-facing interface is fe-0/1/2:

[edit]
protocols {
    pim {
        interface all {
            mode sparse;
            version 2;
        }
        interface fxp0.0 {
            disable;
        }
    }
    igmp {
        interface fe-0/1/2 {
            version 3;
        }
    }
}
