Configuring OSPF and Refresh Reduction for MPLS-TE

Note

A VC type 4 requires one POS interface to be configured for MPLS-TE tunnel and the other POS
interface configured for the 802.1Q tunnel.

Configuring OSPF and Refresh Reduction for MPLS-TE

For a description of the OSPF commands (excluding the OSPF traffic engineering commands), see the
Cisco IOS IP Command Reference, Volume 2 of 3: Routing Protocols

To configure OSPF and Refresh Reduction for MPLS-TE, use the following commands beginning in
global configuration mode .

Configuring an MPLS-TE Tunnel

To configure an MPLS-TE tunnel, use the following commands, beginning in global configuration mode:

Command

Purpose

Step 1

Router(config-if)# mpls traffic-eng tunnels

Enables MPLS-TE tunnels on an RPR (SPR)
interface or on a POS interface.

Step 2

Router(config-if)# ip rsvp bandwidth

bandwidth

Enables RSVP for IP on an interface and specifies
the amount of bandwidth that will be reserved.

For a description of the ip rsvp interface command
syntax, see the Cisco IOS Quality of Service
Solutions Command Reference
.

Command

Purpose

Step 1

Router(config)# router ospf

process-id

Configures an OSPF routing process for IP and places the router in
configuration mode.

The process-id argument is an internally used identification
parameter for an OSPF routing process. It is locally assigned and
can be any positive integer. Assign a unique value for each OSPF
routing process.

Step 2

Router(config-router)# mpls

traffic-eng

area

area-id

Turns on MPLS-TE for a specified OSPF area.

Step 3

Router(config-router)# mpls

traffic-eng

router-id loopback0

Specifies that the traffic engineering router identifier for the node is
the IP address associated with interface loopback0.

Step 4

Router(config)# ip rsvp signalling

refresh reduction

Reduces the messaging load imposed by RSVP
