Oke setelah melakukan konfigurasi routing BGP yang
cukup panjang dan melelahkan selanjutnya
adalah melakukan konfigurasi route filtering pada wawan-R2, wawan-R3, dan wawan-R4 agar router local tidak mendapatkan
routing yang menumpuk melainkan menggunakan default route yang sudah diberikan
oleh wawan-R2,
wawan-R3, dan wawan-R4 ketika konfigurasi BGP Peer tadi.
[admin@wawan-R2]
> /routing filter
add action=discard chain=bgp-out disabled=no invert-match=no
prefix-length=16-32
Setelah itu konfigurasi peer pada setiap router agar
menerapkan route filter yang sudah kita buat tadi.
[admin@wawan-R2]
> /routing bgp peer
set peer1 out-filter=bgp-out
set peer2 out-filter=bgp-out
[admin@wawan-R3] > /routing bgp peer
set peer1 out-filter=bgp-out
[admin@wawan-R4] > /routing bgp peer
set peer1 out-filter=bgp-out
set peer2 out-filter=bgp-out
Lalu lakukan verifikasi pada salah satu router bahwa
route sudah berkurang.

Terlihat bahwa routing table yang tadinya ada banyak
kini telah berkurang. Selanjutnya kita akan memanipulasi jalur. Coba lakukan
traceroute terlebih dahulu dari wawan-R11
menuju wawan-R2.

Terlihat bahwa nexthop yang dilewati hanya ada 2.
Lalu coba kita pindah jalurnya melewati jalur yang lainnya.

add action=accept chain=bgp-prep disabled=yes
invert-match=no prefix=12.12.12.0/24 set-bgp-prepend=1

Setelah itu definisikan in filter pada bgp peer dengan
in-filter menggunakan chain yang sudah kita buat tadi.
[admin@wawan-R4] > /routing bgp peer
set peer1 in-filter=bgp-prep
Lalu lakukan verifikasi traceroute kembali.

Setelah itu maka akan terlihat bahwa jalur yang
digunakan telah berbeda. Selanjutnya kita membatasi prefix yang dapat
diperbolehkan masuk ke dalam sebuah router. Sebelumnya lakukan verifikasi
terlebih dahulu.

Terlihat diatas bahwa pada peer1 terdapat 15 prefix
yang masuk ke dia, kemudian pada peer2 terdapat 14 prefix yang masuk ke dia,
dan pada peer 3 terdapat 1 prefix yang masuk. Lalu kali ini kita akan
mengkonfigurasi maximum prefix yang dapat masuk ke dia. Lalu apa yang terjadi
jika prefix yang masuk melebihi limit tersebut? Mari kita lihat. Konfigurasi
max-prefix-limit pada salah satu peer. Saya akan memilih peer1 dengan
max-prefix-limit 10.

# INSTANCE
REMOTE-ADDRESS REMOTE-AS
0 default 24.24.24.2 100
1 E
default 34.34.34.3 100
2 E
default 11.0.4.11 300
Maka akan terlihat bahwa status established yang ada
pada peer1 akan hilang dikarenakan sudah melebihi prefix yang telah di tentukan
oleh wawan-R4.
Selanjutnya kita akan membuat seluruh perangkat terhubung ke internet. Kali ini
saya akan menggunakan 2 ISP dimana 1 ISP sebagai cadangan, dan 1 lagi menjadi
jalur utama. Saya akan menggunakan konsep fail over menggunakan static route.
[admin@wawan-R1] > /ip route
add check-gateway=ping disabled=no distance=1
dst-address=0.0.0.0/0 gateway=19.19.19.4
add disabled=no distance=1 dst-address=1.0.0.5/32
gateway=12.12.12.2
Lalu lakukan verifikasi tabel routing.
[admin@wawan-R1] > ip route print detail where
dst-address=0.0.0.0/0
Flags: X - disabled, A - active, D - dynamic, C -
connect, S - static, r - rip, b - bgp, o - ospf, m - mme, B - blackhole, U -
unreachable, P - prohibit
0 A S dst-address=0.0.0.0/0 gateway=19.19.19.4
gateway-status=19.19.19.4 reachable via
ether1 check-gateway=ping distance=1 scope=30 target-scope=10
1 S
dst-address=0.0.0.0/0 gateway=10.10.10.4 gateway-status=10.10.10.4
reachable via ether2 distance=2 scope=30
target-scope=10
Maka akan terlihat salah satu link yang aktif dan
satu lagi tidak aktif. Untuk menjadikan seluruh router dapat terkoneksi ke
internet, tambahkan firewall dan dns.
[admin@wawan-RX]
> /ip firewall nat
add action=masquerade chain=srcnat disabled=no
out-interface=(interface internet)
[admin@wawan-RX]
> /ip dns
set allow-remote-requests=yes
servers=8.8.8.8,8.8.4.4
Lalu lakukan
verifikasi pada router local bahwa sudah terhubung ke internet.
