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 Cisco ASR 9000 Series Router module of the Cisco ASR 9000 Series Aggregation
Services Router MPLS Configuration Guide
Before You Begin
Your network must support the following features before you enable MPLS TE for OSPF on your router:
• MPLS
• IP Cisco Express Forwarding (CEF)
OL-30423-03
Purpose
• Use the nsf cisco command with the optional enforce and
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.

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.
