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


Sambungan

R1
e1 --> R3 e1
e2 --> R2 e2 
e3 --> LAN 10.100.100.0/24
e4 --> LAN 10.100.200.0/24

R2
e1 --> R3 e2
e2 --> R1 e2
e3 --> LAN 10.10.10.0/24
e4 --> LAN 10.10.20.0/24

R3
e1 --> R1 e1
e2 --> R2 e1
e3 --> LAN 10.1.1.0/24
e4 --> LAN 10.1.2.0/24


Setup connection

Pastikan semua ifconfig bersih, lakukan langkah BIRD: dari OpenWRT


ISP1 

ifconfig eth1 192.168.1.1 netmask 255.255.255.0
ifconfig eth2 192.168.3.1 netmask 255.255.255.0
ifconfig eth3 10.100.100.1 netmask 255.255.255.0
ifconfig eth4 10.100.200.1 netmask 255.255.255.0


ISP2 

ifconfig eth1 192.168.2.1 netmask 255.255.255.0
ifconfig eth2 192.168.3.2 netmask 255.255.255.0
ifconfig eth3 10.10.10.1 netmask 255.255.255.0
ifconfig eth4 10.10.20.1 netmask 255.255.255.0

ISP3 

ifconfig eth1 192.168.1.2 netmask 255.255.255.0
ifconfig eth2 192.168.2.2 netmask 255.255.255.0
ifconfig eth3 10.1.1.1 netmask 255.255.255.0
ifconfig eth4 10.1.2.1 netmask 255.255.255.0

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.
