Hi…

Kali ini kita akan coba lab dengan menggabungkan ospf, bgp dan rip pada device mikrotik
Topology nya kira-kira seperti gambar berikut :

ospf-bgp-rip
R1-R2-R3 terhubung menggunakan OSPF
R4-R5-R6 terhubung menggunakan RIPv2
R3-R4 terhubung menggunakan BGP

OK,, kita mulai ya

Mulai dari bagian OSPF terlebih dahulu

Nah, sekarang yang jadi pertanyaan adalah bagaimana advertise network OSPF, BGP dan RIP ke router R1,R2,R5 dan R6??
Kita aktifkan redistribute-bgp, redistribute-ospf dan redistribute-rip pada R3 dan R4 yang menjadi penghubung.

Konfig R3

[[email protected]] > routing bgp instance set default redistribute-ospf=yes
[[email protected]] > routing ospf instance set default redistribute-bgp=as-type-1

Konfig R4

[[email protected]] > routing bgp instance set default redistribute-rip=yes
[[email protected]] > routing rip set redistribute-bgp=yes

Verifikasi R3

Dan akhirnya lengkap sudah routing table nya, silahkan cek juga pada R1, R2, R5 dan R6.

Sekarang coba ping dari R1 ke R6 atau dari Router mana saja
