Release Information Statement introduced in Junos OS Release 8.0.
Statement introduced in Junos OS Release 9.0 for EX Series switches.
Description Set the SPT threshold to infinity for a source-group address pair. Last-hop multicast
routing devices 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 routing devices transition to a direct SPT to the source. You
can configure this routing device to set the SPT transition value to infinity to prevent this
transition for any source-group address pair.
The remaining statements are explained separately.
