Contoh Konfigurasi pada Juniper

"configuration protocols bgp"

group iix-rserver2 {
    type external;
    neighbor 103.19.76.2 {
        description "ipv4 IIX-rserver2";
        family inet {
            unicast {
                prefix-limit {
                    maximum 20000;
                }
            }
        }
        peer-as 7597;
    }
}

Contoh Konfigurasi pada Mikrotik

/routing bgp peer
add in-filter="in-iix-ji " max-prefix-limit=20000 max-prefix-restart-time=30s \
    name="rs-iix-ji-1-v4 " out-filter="out-iix-ji " remote-address=103.19.76.2 \
    remote-as=7597 remove-private-as=yes
add in-filter="in-iix-ji " max-prefix-limit=20000 max-prefix-restart-time=30s \
    name="rs-iix-ji-2-v4 " out-filter="out-iix-ji " remote-address=103.19.76.3 \
    remote-as=7597 remove-private-as=yes
add address-families=ipv6 in-filter="in-iix-ji -v6" max-prefix-limit=10000 \
    max-prefix-restart-time=30s name=rs-iix-ji-1-v6 out-filter="out-iix-ji -v6" \
    remote-address=2001:7fa:2:50ba::2:2 remote-as=7597 remove-private-as=yes
add address-families=ipv6 in-filter="in-iix-ji -v6" max-prefix-limit=10000 \
    max-prefix-restart-time=30s name=rs-iix-ji-2-v46 out-filter=\
    "out-iix-ji -v6" remote-address=2001:7fa:2:50ba::2:3 remote-as=7597 \
    remove-private-as=yes

Contoh Penggunaan Community

Cisco

R2(config)# ip bgp-community new-format
R2(config)# access-list 1 permit 203.89.31.0 mask 255.255.255.0
R2(config)# route-map out-no-export permit 10
R2(config-route-map)# match ip address 1
R2(config-route-map)# set community 0:23456
R2(config-route-map)# exit
R2(config)# route-map out-no-export permit 20
R2(config-route-map)# exit
R2(config)# router bgp 24521
R2(config-router)# neighbor 103.19.76.2 send-community
R2(config-router)# neighbor 103.19.76.2 route-map out-no-export out

Juniper

set policy-options community no-advertise members 0:23456
set policy-statement ke-iix-ji term prefix from 203.89.31.0/24 exact
set policy-statement ke-iix-ji term prefix then community add no-advertise
set policy-statement ke-iix-ji term prefix then accept
set policy-statement ke-iix-ji term liyone then reject

Mikrotik

/routing filter
add action=accept bgp-communities=0:23456 chain="out-iix-ji" prefix=203.89.31.0/24
add action=discard chain="out-iix-ji" prefix=0.0.0.0/0 prefix-length=0-32

Hal-hal yang Perlu Dihindari

1. Tidak menerapkan rule filter pada bgp yang akan diaktifkan
2. Kesalahan penulisan commuity tagging
3. Apabila telah selesai konfigurasi bisa dicheck pada looking glass yang tersedia.
