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

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-----------------------
