OSPF and PPPoE Setup

Once we have the IP Addresses, Gateway, and Routing information from our service provider, we can begin by creating and configuring the OSPF area, followed by setting up the PPPoE server. In this example 10.0.108.18/28 is the routing network given to us by the provider, with the gateway 10.0.108.17. The public IP Address block we have been given is 10.0.109.0/24. Once these steps have been completed, the PPPoE username and passwords that are set up will be on the internet with an IP Address out of the 10.0.109.2-10.0.109.254 range. Our public facing network card is ether1.
IP Address Configuration
/ip address add address=10.0.108.18/28 interface=ether1
