PIM-SM Configuration
Example
Network requirements
In actual network, we assume that the switches can intercommunicate and the IP
address of each interface has been configured.
■ LSA is connected to LSB through VLAN-interface10, connected to HostA
through VLAN-interface11 and connected to LSC through VLAN-interface12.
■ LSB is connected to LSA through VLAN-interface10, connected to LSC through
VLAN-interface11 and connected to LSD through VLAN-interface12.
■ LSC is connected to HostB through VLAN-interface10, connected to LSB
through VLAN-interface11 and connected to LSA through VLAN-interface12.
Suppose that Host A is the receiver of the multicast group at 225.1.1.1. Host B
begins transmitting data destined to 225.1.1.1. LSA receives the multicast data
from Host B via LSB.
