Step-1 : (Konfigurasi IP address di semua router P1, P2, P3, PE1, PE2 dan PE3)

Step 2 : (Advertise network dengan routing OSPF). Selanjutnya kita advertise semua network dengan routing protocol OSPF pada seluruh router ISP (P1,P2,P3, PE1, PE2, PE3 )
Router P1
router ospf 1
net 13.13.13.1 0.0.0.0 are 0
net 14.14.14.1 0.0.0.0 are 0
net 15.15.15.1 0.0.0.0 are 0
net 1.1.1.1 0.0.0.0 are 0
exi

Router P2
router ospf 1
net 17.17.17.1 0.0.0.0 are 0
net 16.16.16.2 0.0.0.0 are 0
net 15.15.15.2 0.0.0.0 are 0
net 2.2.2.2 0.0.0.0 are 0

Router P3
router ospf 1
net 13.13.13.2 0.0.0.0 are 0
net 16.16.16.1 0.0.0.0 are 0
net 12.12.12.1 0.0.0.0 are 0
net 3.3.3.3 0.0.0.0 are 0
exi
Router PE1
router ospf 1
net 14.14.14.2 0.0.0.0 are 0
net 11.11.11.11 0.0.0.0 are 0
exi
Router PE2
router ospf 1
net 17.17.17.2 0.0.0.0 are 0
net 22.22.22.22 0.0.0.0 are 0
exi

Router PE3
router ospf 1
net 12.12.12.2 0.0.0.0 are 0
net 33.33.33.33 0.0.0.0 are 0
exi
Verifikasi
#show ip route ospf

 
Step 3 : (Konfigurasi MPLS di  router pada ISP area yaitu: (P1,P2,P3, PE1, PE2 dan PE3)
 Langkah selanjutnya adalah kita masuka konfigurasi MPLS, masih router ISP area.
 

Konfigurasi MPLS di router P1,P2 dan P3
Router P1
mpls label protocol ldp
mpls ldp router-id lo0 force 

int range gi1 - 3
mpls ip
exi
--
Router P2
mpls label protocol ldp
mpls ldp router-id lo0 force 

int range gi1 - 3
mpls ip
exi
---
Router P3
mpls label protocol ldp
mpls ldp router-id lo0 force 

int range gi1 - 3
mpls ip
exit
Router PE1
mpls label protocol ldp
mpls ldp router-id lo0 force 

int gi1 
mpls ip
exi
--
Router PE2
mpls label protocol ldp
mpls ldp router-id lo0 force 

int gi1 
mpls ip
exi
-----------
Router PE3
mpls label protocol ldp
mpls ldp router-id lo0 force 

int gi1 
mpls ip
exi
VERIFIKASI:
#sh mpls ldp neighbor

 Step 4 : (Konfigurasi iBGP di  router PE pada ISP area)

Langkah selanjutnya adalah konfigurasi iBGP antar router PE1, PE dan PE3
Router PE1
router bgp 65010
neighbor PE peer-group 
nei PE remote-as 65010
neighbor PE update-source lo0
nei 22.22.22.22 peer-group PE
nei 33.33.33.33 peer-group PE

address-family vpnv4
neighbor 22.22.22.22 activate 
neighbor 33.33.33.33 activate 
exit
Router PE2
router bgp 65010
neighbor PE peer-group 
nei PE remote-as 65010
neighbor PE update-source lo0
nei 11.11.11.11 peer-group PE
nei 33.33.33.33 peer-group PE

address-family vpnv4
neighbor 11.11.11.11  activate 
neighbor 33.33.33.33 activate 
exit

Router PE3
router bgp 65010
neighbor PE peer-group 
nei PE remote-as 65010
neighbor PE update-source lo0
nei 11.11.11.11 peer-group PE
nei 22.22.22.22 peer-group PE

address-family vpnv4
neighbor 11.11.11.11 activate 
neighbor 22.22.22.22 activate 
exit
Verifkasi di router (PE1, PE2 dan PE3) 
#sh ip bgp all summary

 Step 5 :(Tahap Terahir, konfigurasi router PE&CE)

Sebelum masuk konfigurasi trahir ini,, perlu diketahui untuk RD nya nanti akan menggunakan list berikut. Sebelum masuk konfigurasi trahir ini,, perlu diketahui untuk RD nya nanti akan menggunakan list berikut:

Kantor A -> 10:200
Adapun untuk routing protocol, kita akan menggunakan sesuai list berikut:

Kantor A -> OSPF

Router PE1

ip vrf A
rd 10:200
route-target export 10:200
route-target import 10:200
exi

int gi2
ip vrf forwarding A
no sh
ip add 172.16.10.1 255.255.255.0
exi

router ospf 200 vrf A
router-id 200.200.200.200
net 172.16.10.1 0.0.0.0 are 0
exit

Router PE2

ip vrf A
rd 10:200
route-target export 10:200
route-target import 10:200
exi

int gi2
ip vrf forwarding A
no sh
ip add 172.16.20.1 255.255.255.0
exi

router ospf 200 vrf A
router-id 200.200.200.200
net 172.16.20.1 0.0.0.0 are 0
exit

Router PE3

ip vrf A
rd 10:200
route-target export 10:200
route-target import 10:200
exi

int gi2
ip vrf forwarding A
no sh
ip add 172.16.30.1 255.255.255.0
exi

router ospf 200 vrf A
router-id 200.200.200.200
net 172.16.30.1 0.0.0.0 are 0
exi

 Verifikasi: di router (PE1, PE2, PE3)

#sh ip route vrf A | b Gateway

 

#sh mpls ldp bindings
 

 

 

 

 

 

 





#sh mpls forwarding-table labels 16 detail



 

 


Langkah  terahir adalah  redistribute OSPF ke BGP dan BGP ke OSPF didisisi router PE1, PE2 dan PE3 .

Router PE1
router bgp 65010
address-family ipv4 vrf A
redistribute ospf 200
exi

router ospf 200 vrf A
redistribute bgp 65010 subnets
exi

Router PE2
router bgp 65010
address-family ipv4 vrf A
redistribute ospf 200
exi

router ospf 200 vrf A
redistribute bgp 65010 subnets
exi

Router PE3
router bgp 65010
address-family ipv4 vrf A
redistribute ospf 200
exi

router ospf 200 vrf A
redistribute bgp 65010 subnets
exi

Step 7:  (Langkah paling ahir adalah konfigurasi semua router CE1, CE2 dan CE3)

Router CE1
host CE1
int gi1
no sh
ip add 172.16.10.2 255.255.255.0
int lo0
ip add 10.10.10.10 255.255.255.255
exi

router ospf 200
net 172.16.10.2 0.0.0.0 are 0
net 10.10.10.10 0.0.0.0 are 0
exi

Router CE2
host CE2
int gi1
no sh
ip add 172.16.20.2 255.255.255.0

int lo0
ip add 20.20.20.20 255.255.255.255
exi

router ospf 200
net 172.16.20.2 0.0.0.0 are 0
net 20.20.20.20 0.0.0.0 are 0
exi

Router CE3
host CE3
int gi1
no sh
ip add 172.16.30.2 255.255.255.0

int lo0
ip add 30.30.30.30 255.255.255.255
exi

router ospf 200
net 172.16.30.2 0.0.0.0 are 0
net 30.30.30.30 0.0.0.0 are 0
exi

Selesai...dan Verifkasi..


Sukses...
