[video] MPLS tiket 1

Link Soal 

post ini merupakan capture proses solving tiket 1 MPLS bootcamp kamis malam. part 1 membahas solvin gcheck status service CEF dan menaikan IGP. sisanya dalam bentuk bentuk text ( tidak di videokan :p ) , adapun tahapannya adalah :

1. check service CEF dan IGP ( OSPF )

2. Check BGP

3. Check MP-BGP dan redistribusi ke tiap CE

detail dibawah ..

 

TIKET 2

 

 

Detail TIKET 1

Capture konfigurasi

problem-nya adalah :

- IP cef yang belum aktif di salah satu PE

- Advertise network yang salah di IGP OSPF

- Masalah redistribute dengan CE di MP-BGP tiap2 PE
