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

R3 e1 --> R1 e1 e2 --> R2 e1 e3 --> LAN 10.1.1.0/24 e4 --> LAN 10.1.2.0/24
PC GNS3 tidak baik untuk IPv6, sebaiknya pakai Ubuntu atau Kali.
Setup connection
Pastikan semua ifconfig bersih, lakukan langkah BIRD: dari OpenWRT
ISP1
ifconfig eth1 2001:192:168:1::1/64 ifconfig eth2 2001:192:168:3::1/64 ifconfig eth3 2001:10:100:100::1/64 ifconfig eth4 2001:10:100:200::1/64
ISP2
ifconfig eth1 2001:192:168:2::1/64 ifconfig eth2 2001:192:168:3::2/64 ifconfig eth3 2001:10:10:10::1/64 ifconfig eth4 2001:10:10:20::1/64
ISP3
ifconfig eth1 2001:192:168:1::2/64 ifconfig eth2 2001:192:168:2::2/64 ifconfig eth3 2001:10:1:1::1/64 ifconfig eth4 2001:10:1:2::1/64
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.
