Belajar Mengkonfigurasi MPLS-TE
—————————————————————————-
Topology yang digunakan adalah sebagai berikut:
—————————————————————————-


—————————————————————————-
Purpose: MPLS TE

Comments:
Dynamic Path is chosen after Explicit Path is down.
When Explicit Path is up again, it preempts Dynamic Path within 60 seconds.

Path 1 R1-R3-R4-R5
Path 2 R1-R4-R3-R5
Dynamic
