Lab kali ini adalah lanjutan untuk bagaimana cara konfigurasi MPLS VPN - AToM.
AToM yang akan dibahas adalah untuk L2 transport melalui Ethernet.
Lab 10 - MPLS VPN - AToM - Ethernet
Topologi yang digunakan masih sama dengan lab AToM - Frame Relay.
Router R1 dan R2 akan menjadi router PE pada networks MPLS, sedangkan router R3 dan R4 akan menjadi router CE untuk dikoneksikan melalui transport Ethernet.
Konfigurasi R1 :
mpls ldp router-id Loopback0 force
!
interface Loopback0
ip address 1.1.1.1 255.255.255.255
ip address 1.1.1.1 255.255.255.255

interface FastEthernet0/1
ip address 12.12.12.1 255.255.255.0
mpls ip
ip address 12.12.12.1 255.255.255.0

Konfigurasi R3 :

ip address 34.34.34.3 255.255.255.0
ip address 34.34.34.3 255.255.255.0
Konfigurasi R4 :

ip address 34.34.34.4 255.255.255.0
ip address 34.34.34.4 255.255.255.0
Verifikasi AToM di router R1 dan R2 :

Hasil test ping dari R3 ke R4 maupun sebaliknya :
R3#ping 34.34.34.4
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 34.34.34.4, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 20/48/84 ms
Type escape sequence to abort.

!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 56/75/104 ms

Dari hasil diatas menunjukkan bahwa MPLS VPN - AToM Ethernet sudah terbangun dan ping dari R3 dan R4 sudah OK.
Sehingga koneksi R3 ke R4 seakan akan langsung terhubung dengan kabel secara langsung.
