For example, I will configure the internal BGP protocol in Bird, in my case iBGP was needed in order to transfer user routes from several access servers to a NAT server. As access servers, I configured Accel-ppp (ipoe) and JuniperMX, they all worked simultaneously and balanced users by making an artificial DHCPOFFER delay.
