MPLS TE

MPLS TE (Traffic Engineering)

Dah lama juga mau coba tapi gak kesampaian2 teyuss.
Dalam MPLS kita butuh memberdayakan link agar tidak terjadi penumpukan dan pemilihan rute terbaik dari satu source ke destination.

berikut TE di MPLS yg dapat mencontohkan TE sederhana yg dapat dan mudah di mengerti,
sengaja mengunakan ISIS nanti akan menggunakan OSPF buat lab ke 2 dan ini dynamic route ya..

TE di MPLS selalu menggunakan link-state dan RSVP. karena di link-state terdapat Type-Length-Values (TLVs); OSPF menggunakan type 10 Link-State Advertisements (Opaque LSAs).
