[video] MPLS tiket 1
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
