Routing extensions for discovery of Traffic Engineering Node Capabilities
It is highly desired in several cases, to take into account Traffic Engineering (TE) node capabilities during TE LSP path selection, such as for instance the capability to act as a branch LSR of a P2MP LSP. This requires advertising these capabilities within the IGP. For that purpose, this document specifies OSPF and IS-IS traffic engineering extensions for the advertisement of control plane and data plane traffic engineering node capabilities.
