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]
