Example: Configuring an SSM-Only Domain
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;
}
}
}
