Quick overview/summary Three categories of TE-related sub-TLVs defined in the ID PCE (Path Computation Element) discovery: used in various contexts such as Inter-domain, CPU intensive TE LSP path computation (NP-complete pbs, …), GMPLS, … TE-MESH-GROUP: allows for auto-discovery of TE mesh group members TE-NODE-CAP: used of the advertisement of control and data plane node capabilities (e.g. P2MP TE capable node) Some sub-TLV can be made of sub-TLVs themselves Support of various flooding scopes (link, area, routing) by means of the opaque LSA type (9, 10 or 11) – Defined on a per-capability basis. A router may generate multiple OSPF router information LSAs with different flooding scopes. No specific new elements of procedure as far as OSPF is concerned. |
