MPLS Backbone

MPLS terdiri dari 3 jenis router yaitu :

1. Router P (Provider)

• Terdapat dalam MPLS Domain, P router terhubung dengan router-router lain yang dimiliki service provider
• Pada jaringan MPLS yang tidak terlalu besar terkadang tidak terdapat P router didalamnya untuk menghemat biaya.

2. Router PE (Provider Edge)

• Merupakan router yang terhubung langsung dengan router customer dan juga sekaligus dengan router service provider
• Menjembatani antara network berbasis IP dengan network berbasis MPLS
• Memberikan pelabelan pada paket IP yang masuk ke dalam MPLS Domain
• Melepas pelabelan pada paket yang akan keluar dari MPLS Domain
• PE Router ini sifatnya harus ada pada setiap jaringan MPLS

3. Router CE (Customer Edge)

• Merupakan router yang terdapat di sisi customer
• Pada router CE ini tidak terdapat konfigurasi MPLS apapun
• Konfigurasi routing biasa, bisa static atau dynamic seperti OSPF / EIGRP

Konfigurasi :

R1

R1#conf t

R1(config)#

R1(config)#ho PE-1

PE-1(config)#

PE-1(config)#int lo 0

PE-1(config-if)#ip add 10.10.10.1 255.255.255.255

PE-1(config-if)#

PE-1(config-if)#exit

PE-1(config)#

PE-1(config)#int g1/0

PE-1(config-if)#ip add 192.168.10.1 255.255.255.252

PE-1(config-if)#no sh

PE-1(config-if)#exit

PE-1(config)#

R2

R2(config)#ho P

P(config)#int lo 0

P(config-if)#ip add 10.10.10.10 255.255.255.255

P(config-if)#

P(config-if)#int g1/0

P(config-if)#ip add 192.168.10.2 255.255.255.252

P(config-if)#no sh

P(config-if)#exit

P(config)#

P(config)#

P(config)#int g2/0

P(config-if)#ip add 192.168.20.1 255.255.255.252

P(config-if)#no sh

P(config-if)#

P(config-if)#exit

P(config)#

Setelah itu coba kita test ping terlebih dahulu 

R1

PE1(config)#do ping 192.168.10.2

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 192.168.10.2, timeout is 2 seconds:

!!!!!

Success rate is 100 percent (5/5), round-trip min/avg/max = 3/15/28 ms

R2

P(config)#do ping 192.168.20.2

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 192.168.20.2, timeout is 2 seconds:

!!!!!

Success rate is 100 percent (5/5), round-trip min/avg/max = 18/22/27 ms

R3

PE-2#ping 192.168.20.1

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 192.168.20.1, timeout is 2 seconds:

!!!!!

Success rate is 100 percent (5/5), round-trip min/avg/max = 20/24/31 ms

Ok sudah bisa, setelah itu kita akan membuat dynamic routing ospf 

R1

PE1(config)#rou

PE1(config)#router ospf 1

PE1(config-router)#net 192.168.10.1 0.0.0.0 area 0

PE1(config-router)#net 10.10.10.1 0.0.0.0 area 0

R2

P(config)#router ospf 1

P(config-router)#net 192.168.10.2 0.0.0.0 area 0

P(config-router)#net 192.168.20.1 0.0.0.0 area 0

P(config-router)#net 10.10.10.10 0.0.0.0 area 0

P(config-router)#exit

R3

PE2(config)#router ospf 1

PE2(config-router)#net 192.168.20.2 0.0.0.0 area 0

PE2(config-router)#net 10.10.10.2 0.0.0.0 area 0

Setelah itu kita cek nih terlebih dahulu kemudian kita ping 

R1

PE1(config-router)#do sh ip route

Sekarang kita buat konfigurasi MPLS nya 

R1

PE1(config)#mpls ip

PE1(config)#int g1/0

PE1(config-if)#mpls ip

PE1(config-if)#exit

R2

P(config)#mpls ip

P(config)#int g1/0

P(config-if)#mpls ip

P(config-if)#int g2/0

P(config-if)#mpls ip

R3

PE2(config)#mpls ip

PE2(config)#int g1/0

PE2(config-if)#mpls ip

Sekarang kita coba lihat MPLS nya apakah sudah aktif 

R1

PE1(config)#do sh mpls forwarding
