Configuring MPLS -TE and Fast-Reroute on OSPF

Perform this task to configure MPLS-TE and Fast Reroute (FRR) on OSPF.
Before You Begin
Note Only point-to-point (P2P) interfaces are supported for OSPF multiple adjacencies. These may be either
native P2P interfaces or broadcast interfaces on which the OSPF P2P configuration command is applied
to force them to behave as P2P interfaces as far as OSPF is concerned. This restriction does not apply to
IS-IS.
The tunnel-te interface is not supported under IS-IS.
SUMMARY STEPS
1. configure
2. interface tunnel-te tunnel-id
3. path-option [protecting ] preference-priority {dynamic [pce [address ipv4 address] | explicit {name
pathname | identifier path-number } } [isis instance name {level level} ] [ospf instance name {area area
ID} ] ] [verbatim] [lockdown]
4. Repeat Step 3 as many times as needed.
5. Use the commit or end command.
6. show mpls traffic-eng tunnels [tunnel-number]
DETAILED STEPS

Cisco ASR 9000 Series Aggregation Services Router MPLS Configuration Guide, Release 4.3.x
Configuring MPLS -TE and Fast-Reroute on OSPF
Purpose
Enters global configuration mode.
Configures an MPLS-TE tunnel interface. The range for
the tunnel ID number is 0 to 65535.
Configures an explicit path option for an MPLS-TE tunnel.
OSPF is limited to a single OSPF instance and area.
