Setup connection

Pastikan semua ifconfig bersih, lakukan langkah BIRD: dari OpenWRT

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.
