Ada tiga (3) ISP
ISP1:
IP 192.168.1.1/24 menuju ISP3 IP 192.168.3.1/24 menuju ISP2 AS 10 IP 10.100.100.0/24 IP 10.100.200.0/24
ISP2
IP 192.168.2.1/24 - menuju ISP3 IP 192.168.3.2/24 - menuju ISP1 AS 20 IP 10.10.10.0/24 IP 10.10.20.0/24
ISP3 (kita)
IP 192.168.1.2/24 - menuju ISP1 IP 192.168.2.2/24 - menuju ISP2 AS 30 IP 10.1.1.0/24 IP 10.1.2.0/24

BGP Peering
Consider that IP connectivity between ISPs edge routers and Our Core router is already set up and working properly. So we can start to establish BGP peering to both ISPs.
ISP1:
#set our AS number /routing bgp instance set default as=10 #add BGP peers /routing bgp peer add name=toISP3 remote-address=192.168.1.2 remote-as=30 add name=toISP2 remote-address=192.168.3.2 remote-as=20 # /routing bgp network add network=10.100.100.0/24 synchronize=no add network=10.100.200.0/24 synchronize=no
ISP2:
#set our AS number /routing bgp instance set default as=20 #add BGP peers /routing bgp peer add name=toISP1 remote-address=192.168.3.1 remote-as=10 add name=toISP3 remote-address=192.168.2.2 remote-as=30 # /routing bgp network add network=10.10.10.0/24 synchronize=no add network=10.10.20.0/24 synchronize=no
ISP3:
#set our AS number /routing bgp instance set default as=30 #add BGP peers /routing bgp peer add name=toISP1 remote-address=192.168.1.1 remote-as=10 add name=toISP2 remote-address=192.168.2.1 remote-as=20 # /routing bgp peer set toISP1 in-filter=isp1-in out-filter=isp1-out set toISP2 in-filter=isp2-in out-filter=isp2-out # /routing bgp network add network=10.1.1.0/24 synchronize=no add network=10.1.2.0/24 synchronize=no
Routing Filter
ISP3:
Lakukan
- accept network kita sendiri
- drop semua tabel IP lainnya, karena kita tidak mau menjadi transit provider
- BGP weigth pada salah satu provider
# Outgoing filter ke ISP1: # /routing filter #accept our networks add chain=isp1-out prefix=10.1.1.0/24 action=accept add chain=isp1-out prefix=10.1.2.0/24 action=accept #discard the rest add chain=isp1-out action=discard
# Outgoing filter ke ISP2: # /routing filter #accept our networks and set weight add chain=isp2-out prefix=10.1.1.0/24 action=accept set-bgp-weight=100 add chain=isp2-out prefix=10.1.2.0/24 action=accept set-bgp-weight=100 #discard the rest add chain=isp2-out action=discard
# ISP1 menjadi main # ISP2 menjadi backup # /routing filter add chain=isp1-in action=discard add chain=isp2-in action=discard # /ip route add gateway=192.168.1.1 check-gateway=ping add gateway=192.168.2.1 distance=30 check-gateway=ping
Routing Filter
# Outgoing filter ke ISP1: # /routing filter #accept our networks add chain=isp1-out prefix=10.1.1.0/24 action=accept add chain=isp1-out prefix=10.1.2.0/24 action=accept #discard the rest add chain=isp1-out action=discard
