Example 4-3 illustrates interfaces POS0/1/0 and POS1/0/0 configured for MPLS TE. Those interface commands enable you to specify link attributes, define link flooding thresholds, and control some aspects of FRR behavior. You can configure additional MPLS TE commands under an interface. This command, in combination with its global peer, gives the minimal operational configuration. This command enables MPLS TE on the interface, including the processing of RSVP signaling to set up and tear down TE LSPs. You use the mpls traffic-eng tunnels command to enable MPLS TE on an interface in Cisco IOS. The command is available only in Cisco IOS XR. Tip - You will find the man command useful to obtain online help on a command if you are using the EXEC interface to configure a node. This configuration enables MPLS TE on two interfaces, defines the maximum number of configurable TE LSPs on the node, and disables penultimate hop popping (PHP) on the upstream neighbor when the node acts as ultimate hop.Įxample 4-2 MPLS TE Node Configuration in Cisco IOS XR mpls traffic-eng Example 4-2 shows an MPLS TE node configuration under Cisco IOS XR. Most of the global MPLS TE commands in Cisco IOS have an equivalent in Cisco IOS XR. As the next section describes, you even enable under this configuration mode the physical interfaces that will participate in the MPLS TE network. This command defines a separate configuration mode that groups the MPLS TE configuration, with the exception of the TE extensions for the IGP. You enable MPLS TE on a node using the mpls traffic-eng command in Cisco IOS XR. Mpls traffic-eng reoptimize events link-up The Cisco IOS documentation contains additional command details.Įxample 4-1 MPLS TE Node Configuration in Cisco IOS mpls traffic-eng tunnels See Appendix A, 'Command Reference for Cisco MPLS Traffic Engineering and RSVP,' for a list of MPLS TE node commands in Cisco IOS. The sections ' Path Computation' and ' DiffServ-Aware Traffic Engineering' cover some global commands in more detail. In this case, the commands enable MPLS on the node, logging of setup and teardown of TE LSPs, and path reoptimization when a physical interface becomes operational. Enabling MPLS TE on a global basis does not result in an operational configuration.Įxample 4-1 shows an MPLS TE node configuration in Cisco IOS. They configure different aspects of the global behavior of MPLS TE for a node, including timers, automation, and logging. Those commands are all optional with the exception of the mpls traffic-eng tunnels command. You must configure this global command before you can implement MPLS TE. You enable MPLS TE on a node using the mpls traffic-eng tunnels command in Cisco IOS. The individual command syntax shares significant similarity between Cisco IOS and Cisco IOS XR.

Cisco IOS XR uses a slightly different approach that groups each of those configuration tasks in separate configuration modes that the mpls traffic-eng and rsvp commands define respectively.

Similarly, ip rsvp is the command prefix for entering RSVP-related configuration. Cisco IOS uses mpls traffic-eng as a command prefix for MPLS TE-related configuration. In addition, you may want to enable the TE extensions for your IGP to perform constraint-based routing. The configuration involves mainly the definition of MPLS TE and Resource Reservation Protocol (RSVP) behavior. Enabling MPLS TEĬisco MPLS TE requires configuration at the node and interface (link) levels.

The sections ' Link Information Distribution,' ' Signaling of TE LSPs,' and ' Traffic Selection' explain how to configure the MPLS TE functionality that equivalent sections in Chapter 2 introduced. Then, the section ' Defining a TE Tunnel Interface' discusses how you configure a TE LSP on the headend node. The section ' Enabling MPLS TE' introduces the basic node and interface configuration that enables MPLS TE on a Cisco router. The following sections review the configuration and operation of the most important aspects of Cisco MPLS TE.
