BGP dengan Mikrotik RouterOS + Juniper Olive

Jaringan pada gambar di atas terdiri atas 4 buah router sebagai berikut :

• Palembang : MikroTik RouterOS 3.13
• Prabumulih : Juniper Olive 8.5R1
• Muaraenim : MikroTik RouterOS 3.13
• Baturaja : MikroTik RouterOS 3.13

Router Palembang

Pertama kita lakukan konfigurasi pada router Palembang. Mulai dengan mengganti hostname,

> /system identity set name=Palembang

Lalu set alamat IP,

> /ip address add interface=ether1 address=192.168.100.1/30
> /ip address add interface=ether2 address=192.168.100.13/30
> /ip address add interface=ether3 address=10.10.0.1/16

Set router AS number router ID,

> /routing bgp instance set default as=64501 router-id=10.10.0.1

Dan terakhir set network yang routing-nya akan di-advertise oleh BGP dan dua buah peering dengan router Prabumulih (AS 64502) dan Baturaja (AS 64504),

> /routing bgp network add network=10.10.0.0/16
> /routing bgp peer add name=as_64502 remote-address=192.168.100.2 remote-as=64502
> /routing bgp peer add name=as_64504 remote-address=192.168.100.14 remote-as=64504

Router Prabumulih

Setting dilakukan pada configuration-mode, pertama ubah hostname

[edit]
# set system host-name Prabumulih

Lalu set alamat IP,

[edit]
# set interfaces em0 unit 0 family inet address 192.168.100.2/30
# set interfaces em1 unit 0 family inet address 192.168.100.5/30
# set interfaces em2 unit 0 family inet address 10.20.0.1/16

Set router AS number router ID,

[edit]
# set routing-options autonomous-system 64502
# set routing-options router-id 10.20.0.1

Set peering dengan router Palembang (AS 64501) dan Muaraenim (AS 64503)

[edit]
# set protocol bgp group as_64501 type external
# set protocol bgp group as_64501 neighbor 192.168.100.1
# set protocol bgp group as_64501 peer-as 64501

# set protocol bgp group as_64503 type external
# set protocol bgp group as_64503 neighbor 192.168.100.6
# set protocol bgp group as_64503 peer-as 64503

Buat export policy,

[edit policy-options]
# set policy-statement as_all_export term 1 from protocol direct
# set policy-statement as_all_export term 1 from route-filter 10.20.0.0/16 exact
# set policy-statement as_all_export term 1 then accept

Terapkan policy pada semua BGP group,

[edit]
# set protocol bgp group as_64501 export as_all_export
# set protocol bgp group as_64503 export as_all_export

Dan lakukan commit,

[edit]
# commit

Router Muaraenim

Konfigurasi untuk router Muaraenim sebagai berikut:

/system identity set name=Muaraenim

/ip address add interface=ether1 address=192.168.100.6/30
/ip address add interface=ether2 address=192.168.100.10/30
/ip address add interface=ether3 address=10.30.0.1/16

/routing bgp instance set default as=64503 router-id=10.30.0.1
/routing bgp network add network=10.30.0.0/16

/routing bgp peer add name=as_64502 remote-address=192.168.100.5 remote-as=64502
/routing bgp peer add name=as_64504 remote-address=192.168.100.9 remote-as=64504

Router Baturaja

Konfigurasi untuk router Baturaja sebagai berikut:

/system identity set name=Baturaja

/ip address add interface=ether1 address=192.168.100.9/30
/ip address add interface=ether2 address=192.168.100.14/30
/ip address add interface=ether3 address=10.40.0.1/16

/routing bgp instance set default as=64504 router-id=10.40.0.1
/routing bgp network add network=10.40.0.0/16

/routing bgp peer add name=as_64501 remote-address=192.168.100.1 remote-as=64501
/routing bgp peer add name=as_64503 remote-address=192.168.100.10 remote-as=64503

Check & recheck

Pada MikroTik RouterOS, cek status BGP peering,

> /routing bgp peering status

lalu cek routing table,

> /ip route print

lakukan ping,

[praban@Palembang] > /ping 10.20.0.1 src-address=10.10.0.1

dan traceroute,

[praban@Palembang] > /traceroute 10.20.0.1 src-address=10.10.0.1

Untuk Juniper Olive, cek status BGP peering,

> show bgp neighbor

cek routing table,

> show route

lakukan ping,

praban@Prabumulih> ping 10.10.0.1 source 10.20.0.1

dan traceroute,

praban@Prabumulih> traceroute 10.10.0.1 source 10.20.0.1
