HARI 5 MULTICAST
Multicast Routing
| Multicast | |
| Dense Mode | Trafic Multicast di flood disemua router yang mengaktifkan Multicast pada interface-nya |
| Sparse Mode | Host harus request terlebih dahulu , baru kemudian traffic multicast dikirim, diperlukan RP ( rendezvous Point) sebagai pusat penghubung multicast source dan router2 yang memiliki client dibawahnya.Ada 3Cara penentuan RP :- Static RP- Auto RP ( cisco proprietary) – perlu dense mode untuk mapping agent , sehingga ada sparse-dense- BSR : candidate RP dan Mapping agent dikirimkan melalui PIM message Hop per hop |
Mroute :
S,G : S menunjukan Source ke group, pada Dense-mode
*,G : * menunjukan RP groupe ( Sparse Mode )
—-
command mengaktifkan Multicast :
Router : IP Multicast-routing
Switch : IP Multicast-routing distribute
| IGMP | |
| IGMP Versi 1 | Paket tetap dikirim walaupun user dalam keadaan mati ( tidak efektif) , IGMP v1 sudah tidak dipakai |
| IGMP Versi 2 | Sama dengan V1 , paket tetap dikirim, hanya saja jika berhenti, user memberikan notifikasi prune message, sehingga paket berhenti dikirim jika user selesai / mati |
| IGMP Versi 3 | Support source Filtering |

LAB 3 Sparse Mode – Auto RP
R1 jadi RP mapping agent ( discovery ) juga jadi RP candidate , berjalan hanya di mode sparse-dense which is propertiary CISCO, masih perlu flood ( dense) untuk pemilihan RP –nya.
R1(config)#ip pim send-rp-announce loopback 0 scope 255
R1(config)#ip pim send-rp-discovery scope 255
Jika salah config, akan menjadi dense mode dengan sendirinya.
