Using PIM dense mode on 3 routers, process cpu was 44% every 5minutes running two multicast video streams
after using pim sparse-mode on 3 routers, process cpu was 6% every 5minutes running two multicast video streams.
Router 1
interface fa4
ip pim sparse-mode
exit
interface vlan 10
ip pim sparse-mode
exit
ip pim rp-address 192.168.2.3
Router 2
interface fa4
ip pim sparse-mode
exit
interface vlan 10
ip pim sparse-mode
exit
ip pim rp-address 192.168.2.3
3750 Stack switch
interface vlan 10
ip address 192.168.2.3 255.255.255.0
ip pim sparse-mode
exit
ip pim rp-address 192.168.2.3
end
In this set up, 3750 stack switch is the RP.
