Synopsis
ip pim {sparse-mode | dense-mode | sparse-dense-mode}
no ip pimConfigures
IP multicast routing on the interface
Default
Disabled
Description
This command enables PIM (Protocol-Independent Multicast) and IGMP on the interface.
-
sparse-mode In this mode, the router forwards multicast packets only if it has received a join message from a downstream router or if it has group members directly connected to this interface.
-
dense-mode In this mode, the router forwards multicast packets until it can determine whether there are group members or downstream routers. Unlike
sparse-mode, it doesn’t wait for a join message to begin sending multicast packets.-
sparse-dense-mode This mode allows the router to operate in both
sparse-modeanddense-mode, depending on what the other routers in the multicast group are using.
