Unformatted text preview: Americas Headquarters: Cisco Systems, Inc., 170 West Tasman Drive, San Jose, CA 95134-1706 USA MPLS Traffic Engineering: Inter-AS TE First Published: August 09, 2004 Last Updated: July 11, 2008 The MPLS Traffic Engineering: Inter-AS TE feature provides Autonomous System Boundary Router (ASBR) node protection, loose path reoptimization, stateful switchover (SSO) recovery of label-switched paths (LSPs) that include loose hops, ASBR forced link flooding, Cisco IOS Resource Reservation Protocol (RSVP) local policy extensions for interautonomous system (Inter-AS), and per-neighbor keys: • ASBR node protection—Protects interarea and Inter-AS TE label-switched paths (LSPs) from the failure of an Area Border Router (ABR) or ASBR. • Loose path reoptimization—Allows a Multiprotocol Label Switching (MPLS) traffic engineering (TE) tunnel’s LSPs to traverse hops that are not in the tunnel headend router’s topology database (that is, they are not in the same Open Shortest Path First (OSPF) area, Intermediate System-to-Intermediate System (IS-IS) level, or autonomous system as the tunnel’s headend router). • Loose hop recovery—Supports SSO recovery of LSPs that include loose hops. • ASBR forced link flooding—Helps an LSP cross a boundary into another domain when information in the other domain is not available to the headend router. • Cisco IOS RSVP local policy extensions for Inter-AS—Allows network administrators to create controlled policies for TE tunnels that function across multiple autonomous systems. • Per-neighbor keys—Allows cryptographic authentication to be accomplished on a per-neighbor basis. Finding Feature Information in This Module Your Cisco IOS software release may not support all of the features documented in this module. For the latest feature information and caveats, see the release notes for your platform and software release. To reach links to specific feature documentation in this module and to see a list of the releases in which each feature is supported, use the “Feature Information for MPLS Traffic Engineering: Inter-AS TE” section on page 27 . Finding Support Information for Platforms and Cisco IOS and Catalyst OS Software Images Use Cisco Feature Navigator to find information about platform support and Cisco IOS and Catalyst OS software image support. To access Cisco Feature Navigator, go to http://www.cisco.com/go/cfn . An account on Cisco.com is not required.
