PIM Dense Mode Fallback Prevention in a
Network Following RP Information Loss
Network Following RP Information Loss
The PIM Dense Mode Fallback Prevention in a Network Following RP Information Loss feature enables
you to prevent PIM dense mode (PIM-DM) fallback when all rendezvous points (RPs) fail. Preventing
the use of PIM dense mode is very important to multicast networks whose reliability is critical. This
feature provides a mechanism to keep the multicast groups in sparse mode, thereby preventing dense
mode flooding.
