Multicast IPv6 dengan Bootstrap

Pada IPV6, tidak ada Multicast dense mode. Sehingga secara default mode yang tersedia adalah multicast sparse mode. Tanpa dikonfigurasi pun sudah available pada router tersebut.
Selain itu, pada IPV6 tidak terdapat RP, sehingga yang dikonfigurasi adalah Bootstrap (BSR)
Join group multicast tidak menggunakan IGMP, melainkan MLD (Multicast listening Discovery).
 
Yang akan di Lab kan kali ini adalah topologi sederhana berikut ini :
 
 Konfigurasi R1 :

ipv6 unicast-routing

ipv6 multicast-routing
!
interface Loopback0
 no ip address
 ipv6 address 1::1/128
 ipv6 ospf 1 area 0
!
interface Ethernet0/0
 no ip address
 ipv6 address 12::1/120
 ipv6 ospf 1 area 0

ipv6 pim bsr candidate bsr 1::1
ipv6 pim bsr announced rp 1::1
ipv6 router ospf 1
 router-id 1.1.1.1

Konfigurasi R2 :

ipv6 unicast-routing

ipv6 multicast-routing

interface Loopback0
 no ip address
 ipv6 address 2::2/128
 ipv6 mld join-group FF03::1
 ipv6 ospf 1 area 0
!
interface Ethernet0/0
 no ip address
 ipv6 address 12::2/120
 ipv6 ospf 1 area 0

ipv6 router ospf 1
 router-id 2.2.2.2

Verifikasi :
R2#sh ipv6 pim bsr election
PIMv2 BSR information

BSR Election Information
  Scope Range List: ff00::/8
     BSR Address: 1::1
     Uptime: 00:07:58, BSR Priority: 0, Hash mask length: 126
     RPF: FE80::30FF:FE00:100,Ethernet0/0
     BS Timer: 00:01:13

R1#sh ipv6 pim bsr election
PIMv2 BSR information

BSR Election Information
  Scope Range List: ff00::/8
  This system is the Bootstrap Router (BSR)
     BSR Address: 1::1
     Uptime: 00:08:27, BSR Priority: 0, Hash mask length: 126
     RPF: FE80::30FF:FE00:100,Loopback0
     BS Timer: 00:00:34
  This system is candidate BSR
      Candidate BSR address: 1::1, priority: 0, hash mask length: 126

R1#ping ff03::1
Output Interface: loopback0
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to FF03::1, timeout is 2 seconds:
Packet sent with a source address of 1::1
