Belajar Simulasi CISCO MPLS-L3VPN (PE-CE OSPF)

18 February 2010
Belajar Simulasi CISCO MPLS-L3VPN (PE-CE with OSPF)
(PE-To-CE OSPF with same process ID)

Topology yang saya gunakan adalah seperti gambar dibawah ini:


Konfigurasi IP addressnya adalah sebagai berikut:



Langkah-langkahnya adalah sebagai berikut:

Pertama:
configure semua interface (PE1-Core-PE2)

---------------core----------------------
!
interface Loopback0
 ip address 192.168.100.1 255.255.255.255
!
interface GigabitEthernet1/0
 ip address 192.168.10.10 255.255.255.252
!
interface GigabitEthernet2/0
 ip address 192.168.10.13 255.255.255.252
-----------------------------------------

---------------PE1-----------------------
interface Loopback0
 ip address 192.168.100.2 255.255.255.255
!
interface GigabitEthernet1/0
 ip address 192.168.10.9 255.255.255.252
-----------------------------------------

---------------PE2-----------------------
interface Loopback0
 ip address 192.168.100.3 255.255.255.255
!
interface GigabitEthernet1/0
 ip address 192.168.10.14 255.255.255.252
-----------------------------------------

Kedua:Aktifkan Dynamic Routing 

---------------core----------------------
router ospf 1
 network 192.168.10.0 0.0.0.255 area 0
 network 192.168.100.1 0.0.0.0 area 0
-----------------------------------------

---------------PE1-----------------------
router ospf 1
 network 192.168.10.0 0.0.0.255 area 0
 network 192.168.100.2 0.0.0.0 area 0
-----------------------------------------

---------------PE2-----------------------
router ospf 1
 network 192.168.10.0 0.0.0.255 area 0
 network 192.168.100.3 0.0.0.0 area 0
-----------------------------------------
untuk pengecekan : ketikan show ip route

PE1#sh ip route
Codes: C - connected, S - static, R - RIP, M - mobile, B - BGP
 D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
 N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
 E1 - OSPF external type 1, E2 - OSPF external type 2
 i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2
 ia - IS-IS inter area, * - candidate default, U - per-user static route
 o - ODR, P - periodic downloaded static route

Gateway of last resort is not set

 192.168.10.0/30 is subnetted, 2 subnets

Gateway of last resort is not set

 192.168.10.0/30 is subnetted, 2 subnets
O       192.168.10.8 [110/2] via 192.168.10.13, 00:18:13, GigabitEthernet1/0
C       192.168.10.12 is directly connected, GigabitEthernet1/0
 192.168.100.0/32 is subnetted, 3 subnets
O       192.168.100.1 [110/2] via 192.168.10.13, 00:18:23, GigabitEthernet1/0

-----------------------------------------
untuk pengecekan : ketikan show ip bgp sum

PE1# sh ip bgp summary
