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 a 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.
