BIRD: Static Routing Sederhana

Topologi

R1
e1 --> CLOUD nat0
e2 --> R2 e1
e3 --> LAN 192.168.1.1/24

R2
e1 --> R1 e2
e2 --> LAN 192.168.2.1/24

Jika menggunakan BIRD appliance di GNS3, maka PC / laptop kita perlu menjalankan

sudo chown root:onno /dev/kvm

Tapi jika menggunakan BIRD VirtualBox (dari OpenWRT), kita tidak perlu menjalankan perintah di atas.

Konfigurasi Shell

R1:

ifconfig eth1 192.168.122.100 netmask 255.255.255.0
ifconfig eth2 172.16.1.1 netmask 255.255.255.252
ifconfig eth3 192.168.1.1 netmask 255.255.255.0

R2:

ifconfig eth1 172.16.1.2 netmask 255.255.255.252
ifconfig eth2 192.168.2.1 netmask 255.255.255.0

Routing

R1:

# vi /usr/local/etc/bird6.conf  # BIRD appliance di GNS3
vi /etc/bird.conf               # BIRD di OpenWRT

edit

router id 172.16.1.1; 
#
protocol direct {                                                    
        interface "-eth*", "*"; # Restrict network interfaces it works with
}   
#
protocol static {                                                               
       route 192.168.2.0/24 via 172.16.1.2;
} 

Restart BIRD

killall bird6
/usr/local/sbin/bird6 -u gns3 -g staff &

R2:

# vi /usr/local/etc/bird6.conf  # BIRD appliance di GNS3
vi /etc/bird.conf

edit

router id 172.16.1.2;

ipv4 table master4;
ipv6 table master6;
                   
ipv4 table mcast4;
ipv6 table mcast6;
                 
ipv4 table mtab4;
ipv6 table mtab6;
                  
vpn4 table vpntab4;
vpn6 table vpntab6;
                  
vpn4 table vpn4mc;
vpn6 table vpn6mc;
                    
flow4 table flowtab4;
flow6 table flowtab6;
                    
protocol direct {                                                          
        interface "-eth*", "*"; # Restrict network interfaces it works with
}                                                                          
                        
protocol static static4 {
        ipv4;                               
        route 192.168.1.0/24 via 172.16.1.1;
}                                           

Restart BIRD

# BIRD appliance di GNS3
# killall bird6
# /usr/local/sbin/bird6 -u gns3 -g staff &

# BIRD di OpenWRT

Test

R1:

ping 172.16.1.2
