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
