Multicast routing Dense Mode

Pada lab kali ini akan dibahas tentang multicast Dense mode dengan topologi sederhana.







Konfigurasi pada R1 :

ip multicast-routing

interface Loopback0
 ip address 1.1.1.1 255.255.255.255
 ip pim dense-mode
!
interface Ethernet0/0
 ip address 12.12.12.1 255.255.255.0
 ip pim dense-mode
!
router ospf 1
 network 0.0.0.0 255.255.255.255 area 0

Konfigurasi pada R2 :

ip multicast-routing

interface Loopback0
 ip address 2.2.2.2 255.255.255.255
 ip pim dense-mode
!
interface Ethernet0/0
 ip address 12.12.12.2 255.255.255.0
 ip pim dense-mode
!
interface Ethernet0/1
 ip address 23.23.23.2 255.255.255.0
 ip pim dense-mode

router ospf 1
 network 0.0.0.0 255.255.255.255 area 0

Konfigurasi pada R3 :

ip multicast-routing

interface Loopback0
 ip address 3.3.3.3 255.255.255.0
 ip pim dense-mode
 ip igmp join-group 239.0.0.1 --------->> int loopback 0 join ke group multicast ini
!
interface Ethernet0/0
 ip address 23.23.23.3 255.255.255.0
 ip pim dense-mode
!
router ospf 1
 network 0.0.0.0 255.255.255.255 area 0

Verifikasi

R1#ping 239.0.0.1
Type escape sequence to abort.
Sending 1, 100-byte ICMP Echos to 239.0.0.1, timeout is 2 seconds:

saat kita melakukan ping ke multicast address yang join ke int loopback R3, maka akan dapat reply dari int loopback tersebut. IP address 3.3.3.3 adalah milik interface loopback R3.
