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.
