MPLS-VPN with EIGRP

Konfigurasi IP addressnya adalah sebagai berikut:

berikut adalah contoh konfigurasinya:

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

config antar P dan PE menggunakan OSPF
