Configuring Shared Trees Only for ASM

You can configure shared trees only on the last-hop router for Any Source Multicast (ASM) groups, which
means that the router never switches over from the shared tree to the SPT when a receiver joins an active
group. You can specify a group range where the use of shared trees is to be enforced with the match ip[v6]
multicast command. This option does not affect the normal operation of the router when a source tree join-prune
message is received.
Note The Cisco NX-OS software does not support the shared-tree feature on vPCs. For more information about
vPCs, see the Cisco Nexus 7000 Series NX-OS Interfaces Configuration Guide, Release 6.x
The default is disabled, which means that the software can switch over to source trees.
Note In ASM mode, only the last-hop router switches from the shared tree to the SPT.
Configuring Shared Trees Only for ASM (PIM)
Before you begin
Ensure that you have installed the Enterprise Services license and enabled PIM.
