bd40bc7c7a Verifying Configuration of MPLS Switching To verify that Cisco Express Forwarding has been configured properly, issue the show ip cef summary command, which generates output similar to that shown below: SUMMARY STEPS1. Use these resources to install and configure the software and to troubleshoot and resolve technical issues with Cisco products and technologies. A data structure in which destinations and incoming labels are associated with outgoing interfaces and labels. For more information about MPLS forwarding commands, see the Multiprotocol Label Switching Command Reference. enable 2. In MPLS traffic engineering, factors such as bandwidth requirements, media requirements, and the priority of one traffic flow versus another can be taken into account. Verifying Configuration of MPLS Forwarding To verify that MPLS forwarding has been configured properly, issue the show mpls interfaces detail command, which generates output similar to that shown below: SUMMARY STEPS1.
Step2 configure terminal Example: Device# configure terminal Enters global configuration mode. An account on Cisco.com is not required. enable 2. What to Do Next Configure either of the following: MPLS Label Distribution Protocol (LDP). This capability of an ATM switch stems from the fact that the MPLS forwarding paradigm, namely, label swapping, is exactly the same as the forwarding paradigm provided by ATM switch hardware. In Cisco IOS XE Release 3.5S, support was added for the Cisco ASR 903 Router. In label switching, the analysis of the Layer 3 header is done only once. Distribution of Label Bindings Each> label switching router (LSR) in the network makes an independent, local decision as to which label value to use to represent a forwarding equivalence class.
