mpls traffic-eng interface
To enable Multiprotocol Label Switching (MPLS) Traffic Engineering (TE) link-state advertisement
(LSA) for an interface to be advertised into the Open Shortest Path First (OSPF) area 0, use the mpls
traffic-eng interface command in router configuration mode. To restore the setting of the MPLS TE
LSA to the same area as the router LSA, use the no form of this command.

Syntax Description

Command Modes Router configuration
Command History
Usage Guidelines Usually, the MPLS TE LSA is advertised into the same
area as the router LSA. If a link between two
Area Border Routers (ABRs) is in an OSPF area besides area 0, you can advertise the link between ABRs
into area 0. This solves for TE the same problem that virtual links solve for IP routing. This command
is valid only for OSPF. Issue the command on both ABRs for the interfaces at both ends of the link.
Examples In the following example, OSPF adv
ertises the MPLS TE LSA for interface pos2/0 to area 0:
Router(config)# router ospf 1
Router(config-router)# mpls traffic-eng interface pos2/0 area 0
