Configuring OSPF Version 2 for MPLS Traffic Engineering

This task explains how to configure OSPF for MPLS TE. This task is optional.
For a description of the MPLS TE tasks and commands that allow you to configure the router to support
tunnels, configure an MPLS tunnel that OSPF can use, and troubleshoot MPLS TE, see Implementing MPLS
Traffic Engineering on module of the MPLS Configuration Guide for Cisco NCS 6000 Series Routers
Before you begin
Your network must support the following features before you enable MPLS TE for OSPF on your router:
• MPLS
Purpose
Sets the minimum time between NSF restart attempts.
Note
Sets the maximum time allowed for external route learning
in seconds.
Sets the maximum route lifetime of NSF following a restart
in seconds.
Enables ietf graceful restart.

Configuring OSPF Version 2 for MPLS Traffic Engineering
• Use the nsf cisco command without the optional
enforce and global keywords to abort the NSF restart
mechanism on the interfaces of detected non-NSF
neighbors and allow NSF neighbors to function
properly.
• Use the nsf cisco command with the optional enforce
and global keywords if the router is expected to
perform NSF during restart. However, if non-NSF
neighbors are detected, NSF restart is canceled for the
entire OSPF process.
When you use this command, the OSPF process
must be up for at least 90 seconds before OSPF
attempts to perform an NSF restart.
