Tujuan Lab

Seluruh Router dapat berkomunikasi menggunakan Routing Protocol BGP, OSPF, dan RIP sisanya menggunakan Static Routing. untuk mengurangi jumlah iBGP Peering maka kita menggunakan Route-Reflector pada R1, informasi yang didapat dari BGP yang masuk juga akan kita filter untuk memodifikasi nilai Scope dan Target scope agar menjadi Recrusive Gateway.

Antar Routing protocol juga melakukan Redistribute.

Konfigurasi RIP (R2, R8, R7)


    IP Address

    Pertama kita berikan alamat IP pada setiap Interface ketiga Router tersebut

      R2

      /ip address
add address=12.12.12.2/24 interface=ether1 network=12.12.12.0
add address=27.27.27.2/24 interface=ether2 network=27.27.27.0
add address=28.28.28.2/24 interface=ether3 network=28.28.28.0

      R8

      /interface bridge
add name=lo0
/ip address
add address=28.28.28.8/24 interface=ether1 network=28.28.28.0
add address=80.80.80.80 interface=lo0 network=80.80.80.80

      R7

      /interface bridge
add name=lo0
/ip address
add address=27.27.27.7/24 interface=ether1 network=27.27.27.0
add address=70.70.70.70 interface=lo0 network=70.70.70.70

    Routing RIP

    Konfigurasi Routing RIP agar antar Router dapat bertukar informasi Routing, masukan network yang ingin di advertise pada Router lainnya.

      R2

      Pada Router ini juga menjalankan BGP, maka konfigurasi redistribute dari RIP menjadi BGP pada Router R2 ini 
      /routing rip
set redistribute-bgp=yes redistribute-connected=yes
/routing rip network
add network=27.27.27.0/24
add network=28.28.28.0/24

      R8

      /routing rip network
add network=28.28.28.0/24
add network=80.80.80.80/32

      R7

      /routing rip network
add network=27.27.27.0/24
add network=70.70.70.70/32

Konfigurasi OSPF (R3, R5, R6)


    IP Address

      R3

      /ip address
add address=13.13.13.3/24 interface=ether1 network=13.13.13.0
add address=36.36.36.3/24 interface=ether2 network=36.36.36.0
add address=35.35.35.3/24 interface=ether3 network=35.35.35.0

      R5

      /interface bridge
add name=lo0
/ip address
add address=35.35.35.5/24 interface=ether1 network=35.35.35.0
add address=50.50.50.50 interface=lo0 network=50.50.50.50

      R6

      /interface bridge
add name=lo0
/ip address
add address=36.36.36.6/24 interface=ether1 network=36.36.36.0
add address=60.60.60.60 interface=lo0 network=60.60.60.60

    Routing OSPF

      R3

      Pada Router ini akan melakukan redistribute OSPF ke BGP dan sebaliknya. 
      /routing ospf area
set [ find default=yes ] disabled=yes
/routing ospf instance
set [ find default=yes ] disabled=yes
add name=lab-ospf redistribute-bgp=as-type-2 redistribute-connected=as-type-2 \
    router-id=3.3.3.3
/routing ospf area
add instance=lab-ospf name=backbone-lab
/routing ospf network
add area=backbone-lab network=35.35.35.0/24
add area=backbone-lab network=36.36.36.0/24

      R5

      /routing ospf area
set [ find default=yes ] disabled=yes
/routing ospf instance
set [ find default=yes ] disabled=yes
add name=lab-ospf router-id=5.5.5.5
/routing ospf area
add instance=lab-ospf name=backbone-lab
/routing ospf network
add area=backbone-lab network=35.35.35.0/24
add area=backbone-lab network=50.50.50.50/32

      R6

      /routing ospf area
set [ find default=yes ] disabled=yes
/routing ospf instance
set [ find default=yes ] disabled=yes
add name=lab-ospf router-id=6.6.6.6
/routing ospf area
add instance=lab-ospf name=backbone-lab
/routing ospf network
add area=backbone-lab network=36.36.36.0/24
add area=backbone-lab network=60.60.60.60/32

Konfigurasi Static

Pada daerah ini hanya menggunakan Static Routing

    IP Address

      R4

      /ip address
add address=14.14.14.4/24 interface=ether1 network=14.14.14.0
add address=41.41.41.4/24 interface=ether2 network=41.41.41.0
add address=49.49.49.4/24 interface=ether3 network=49.49.49.0

      R9

      /interface bridge
add name=lo0
/ip address
add address=49.49.49.9/24 interface=ether1 network=49.49.49.0
add address=90.90.90.90 interface=lo0 network=90.90.90.90

      R10

      /interface bridge
add name=lo0
/ip address
add address=41.41.41.10/24 interface=ether1 network=41.41.41.0
add address=100.100.100.100 interface=lo0 network=100.100.100.100

    Static Routing

      R4

      /ip route
add distance=1 dst-address=90.90.90.90/32 gateway=49.49.49.9
add distance=1 dst-address=100.100.100.100/32 gateway=41.41.41.10

      R9

      /ip route
add distance=1 gateway=49.49.49.4

      R10

      /ip route
add distance=1 gateway=41.41.41.4

Konfigurasi BGP AS 1234 (R1, R2, R3 & R4)


Seluruh Router peering iBGP pada satu Router yang sama yaitu R1 yang akan bertindak sebagai Route Reflector Server. Pada R1 konfigurasikan IP Address terlebih dahulu :

R1

/ip address
add address=14.14.14.1/24 interface=ether2 network=14.14.14.0
add address=13.13.13.1/24 interface=ether3 network=13.13.13.0
add address=12.12.12.1/24 interface=ether4 network=12.12.12.0

    BGP Peering

    Konfigurasi BGP Peering pada setiap Router agar terbentuk koneksi BGP antar Router

      R1

      Router R1 ini berperan sebagai Route-Reflector Server 
      /routing bgp instance
set default disabled=yes
add as=1234 name=lab-bgp router-id=1.1.1.1
/routing bgp network
add network=12.12.12.0/24
add network=13.13.13.0/24
add network=14.14.14.0/24
/routing bgp peer
add instance=lab-bgp name=peer1 nexthop-choice=force-self remote-address=\
    12.12.12.2 remote-as=1234 route-reflect=yes
add instance=lab-bgp name=peer2 nexthop-choice=force-self remote-address=\
    13.13.13.3 remote-as=1234 route-reflect=yes
add instance=lab-bgp name=peer3 nexthop-choice=force-self remote-address=\
    14.14.14.4 remote-as=1234 route-reflect=yes

      R2

      Tambahkan in-filter untuk melakukan fitering terhadap informasi yang masuk 
      /routing bgp instance
set default disabled=yes
add as=1234 name=lab-bgp redistribute-connected=yes redistribute-rip=yes \
    router-id=2.2.2.2
/routing bgp network
add network=12.12.12.0/24
/routing bgp peer
add in-filter=bgp-scope-in instance=lab-bgp name=peer1 remote-address=\
    12.12.12.1 remote-as=1234

      R3

      /routing bgp instance
set default disabled=yes
add as=1234 name=lab-bgp redistribute-connected=yes redistribute-ospf=yes \
    router-id=3.3.3.3
/routing bgp network
add network=13.13.13.0/24
/routing bgp peer
add in-filter=bgp-in-scope instance=lab-bgp name=peer1 remote-address=\
    13.13.13.1 remote-as=1234

      R4

      /routing bgp instance
set default disabled=yes
add as=1234 name=lab-bgp redistribute-connected=yes redistribute-static=yes \
    router-id=4.4.4.4
/routing bgp network
add network=14.14.14.0/24
/routing bgp peer
add in-filter=bgp-in-scope instance=lab-bgp name=peer1 remote-address=\
    14.14.14.1 remote-as=1234
      Setelah itu coba cek salah satu Routing table ROuter dan lihat apa yang terjadi

      Seperti yang kita lihat rute yang didapatkan BGP belum aktif, karena apa? rute tersebut bersifat recrusive dan seperti yang kita ketahui untuk mengaktifkan recrusive maka kita harus mengubah nilai scope dan target scopenya. jadi solusinya kita filter rute yang masuk untuk mengubah nilai scope dan target scope nya

    BGP Filter

    Kita akan melakukan filtering terhadap informasi rute BGP yang masuk, informasi yang masuk tersebut akan diubah nilai scopenya agar menjadi recrusive.

      R2

      /routing filter
add chain=bgp-scope-in set-scope=30 set-target-scope=40

      R3

      /routing filter
add chain=bgp-scope-in set-scope=30 set-target-scope=40

      R4

      /routing filter
add chain=bgp-scope-in set-scope=30 set-target-scope=40
      Setelah itu kembali cek di Routing table apakah sudah menjadi aktif
