MPLS Traffic Engineering: Interarea Tunnels
First Published: January 16, 2003
Last Updated: January 4, 2007 
The MPLS Traffic Engineering: Interarea Tunnels feature allows you to establish Multiprotocol Label 
Switching (MPLS) traffic engineering (TE) tunnels that span multiple Interior Gateway Protocol (IGP) 
areas and levels, removing the restriction that had required the tunnel headend and tailend routers both 
be in the same area. The IGP can be either Intermediate System-to-Intermediate System (IS-IS) or Open 
Shortest Path First (OSPF).
