We are going to revisit these PE devices a couple of times throughout the configs, but for now we are going to: 1. Configure the interfaces connected to the P routers and create a Loopback0 using 172.22.2.x, where x is the PE router number. 2. Create the OSPF 30 instance using interface configurations 3. Create […]

The P Routers These are the Provider Core routers. They run the MPLS (MultiProtocol Label Switching) core between PE (Provider Edge) devices. They are also called LSR (Label Switching Routers) We are going to run OSPF in our core in process 30 area 0 We will run OSPF on all interfaces (including Loopbacks) We will […]
