Release Information

Statement introduced in JUNOS Release 8.0.

Description

Last-hop multicast routers running PIM sparse mode can forward the same stream of multicast packets onto the same LAN through an RPT rooted at the RP or an SPT rooted at the source. By default, last-hop routers transition to a direct SPT to the source. You can configure this router to set the SPT transition value to infinity to prevent this transition for any source-group address pair.

Options

The statement is explained separately.
