Description: In this example network is configured with OSPF as routing protocol. Then run MPLS over the IP network.
Network Diagram :
Instructions:
1. Assign the IP addresses to all the devices
2. Enable MPLS family on the interfaces
3. Enable MPLS and LDP protocol on the interfaces
4. Enable OSPF (use area number as 100) on all the interfaces of all the devices
5. Issue ping and trace route command to check the connectivity
