Deploying an SSM-only domain is much simpler than deploying an ASM domain; 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;
- }
- }
- }
