no ip multicast-routing permanent-mroute
Command introduced before JUNOSe Release 7.1.0.
Specifies that newly created mroutes that match the specified access list do not get timed out. The no version of this command prevents any new mroutes from becoming permanent. However, it does not remove any existing permanent mroutes. To remove existing permanent mroutes, use the clear ip mroute command.
