The setup of a full mesh of Multi-Protocol Label Switching (MPLS)

Traffic Engineering (TE) Label Switched Paths (LSP) among a set of

Label Switch Routers (LSR) is a common deployment scenario of MPLS

Traffic Engineering either for bandwidth optimization, bandwidth

guarantees or fast rerouting with MPLS Fast Reroute.  Such deployment

may require the configuration of a potentially large number of TE

LSPs (on the order of the square of the number of LSRs).  This document

specifies Interior Gateway Protocol (IGP) routing extensions for

Intermediate System-to-Intermediate System (IS-IS) and Open Shortest

Path First (OSPF) so as to provide an automatic discovery of the set

of LSRs members of a mesh in order to automate the creation of such

mesh of TE LSPs.  [STANDARDS TRACK]
