multicast lab - GNS3
setup the lab as below, bear in mind that multicast is depend on the routing table, so make sure all network are reachable to each other. enable the multicast routing on both router, R1 and R2 R1(config)#ip multicast-routing configure PIM on the interfaces R1 : fa0/0 and ser0/0 and R2 fa0/0 and ser0/0 R1 interface FastEthernet0/0 ip address 192.168.1.99 255.255.255.0 ip pim sparse-dense-mode duplex auto speed auto end interface Serial0/0 ip address 10.1.1.1 255.255.255.252 ip pim sparse-dense-mode clock rate 56000 end R2 interface FastEthernet0/0 ip address 172.16.1.99 255.255.255.0 ip pim sparse-dense-mode duplex auto speed auto end interface Serial0/0 ip address 10.1.1.2 255.255.255.252 ip pim sparse-dense-mode end this is it !! now our multicast traffic should run smoothly on our network. But how to test, there's a few method out there, but let's try this way first. we...
