In normal IP based networks, packets are forwarded by routers after looking at the destination address and making a decision on where to forward them based on its routing table or other configuration such as policy routing. Every router that receives a packet in a normal IP based network makes this decision based on the destination address. With MPLS, the core routers do not need to be bogged down with the extra requirement of running BGP and they will forward packets just fine using labels. We can explain how packets are forwarded using labels in MPLS through the following diagram.

LSR3 does the same using a label of L3. As you can see, there is minimal configuration on the CE routers. They have a default route to their respective PE routers and I used the Loopback interfaces to simulate the network connected to the CE routers. It must also be enabled on the MPLS forwarding interface if it was disabled using the ip route-cache cef command. Enabling MPLS on an interface is actually very simple: you use the command mpls ip under the interface configuration.

This command in effect enables LDP on that interface.

This will automatically enable LDP on the interfaces that are configured to run the routing protocol. In case there are no loopback interfaces configured with IP addresses, it will pick the highest IP address configured on the router. It relates to how the customer network routes are carried and we will talk about it later. Simple enough right?

The first one we will use is the show mpls interfaces command. The Tunnel column shows information specific to Traffic Engineering. The Operational column lets us know that packets are being labeled on that interface. Another useful command which gives information about LDP neighbors is the show mpls ldp neighbor command.

In the next article, we will look deeper into LDP. I hope you have found this article helpful. I simulated this on GNS3, the P2 router will not have a route to both Could you explain why?
