IPv6: VyOS: BGP Sederhana
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
Setiap kali menjalankan VM VyOS di GNS3, lakukan
sudo chown root:useranda /dev/kvm
sebelum me-RUN setiap VM VyOS satu per satu.

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.
