Example: Configuring Externally Facing PIM Border Routers

In this example, you add the scope statement at the [edit routing-options multicast] hierarchy level to prevent auto-RP traffic from “leaking” into or out of your PIM domain. Two scopes defined below, auto-rp-39 and auto-rp-40, are for specific addresses. The scoped-range statement defines a group range, thus preventing group traffic from leaking.

routing-options {multicast {scope auto-rp-39 {prefix 224.0.1.39/32;interface t1-0/0/0.0;}scope auto-rp-40 {prefix 224.0.1.40/32;interface t1-0/0/0.0;}scope scoped-range {prefix 239.0.0.0/8;interface t1-0/0/0.0;}}}
