MPLS LDP configuration in Cisco IOS
- [Instructor] For enabling MPLS LDP on Cisco iOS, first ensure that CEF, or Cisco Express Forwarding, is enabled. This feature is typically enabled by default, but can be explicitly enabled with the IP CEF command. Then, ensure that MPLS is enabled, which is typically enabled by default in Cisco iOS. You can activate it using the command MPLS IP in Global Configuration mode. Now, we have two methods for configuring MPLS. The first method is to use the MPLS IP command on all router interfaces. This is known as the Interface Specific method. The second method is the IGP Configuration method. If you are using OSPF or IS-IS as your IGP, you can enable MPLS LDP on all interfaces that are enabled with the IGP, by using the MPLS LDP Autoconfig command under the routing protocol process. In our scenario, I will enable MPLS on R1 and R2, using the Interface Configuration method, and on R3 and R4, using the IGP Configuration method with OSPF or IS-IS. If you want routers to choose MPLS labels…
