Configuring PIM PIM Overview
OmniSwitch 6800/6850/9000 Advanced Routing Configuration Guide December 2007 page 7-11
Sender 1 sends multicast data to its Designated Router (DR). The source DR then unicast-encapsulates the
data into PIM-SM Register messages and sends them on to the RP.
Once the distribution tree for group G is learned at the RP, the encapsulated data being sent from the
source DR are now unencapsulated at the RP and forwarded natively to the Receiver.
