Hi, I have a few questions regarding IGPs (e.g., OSPF) and MPLS TE and would appreciate any answers. 1. When an LSP is established and IGP traffic engineering is being performed, should the LSP be informed as a (logical) Router link and/or a TE LSA link into OSPF? If not, how is traffic engineering for IGP destinations performed, is it completely internal to the Ingress node? 2. If the available/unreseved bandwidth or some other TE parameter on a link changes when a new LSP is established, should the change be made known immediately to OSPF and OSPF originate a new TE LSA? 3. Should CSPF path computations occur as a result of an updated TE LSA or are they done only when a new LSP is to be setup or existing LSPs optimized etc.? 4. Should a LSP be specifically designated as an FA-LSP (draft-kompella-lsp-hierarchy-00.txt) or can any LSP established function as an FA-LSP if the LSP is advertised into OSPF? 5. Sec 4.2 of draft-kompella-lsp-hierarchy-00.txt mentions how a FA-LSP/forwarding adjacency can be restricted to allow its usage only for MPLS TE LSPs. So, is there an Internet draft which defines how an LSP should be advertised as a regular LSA into OSPF? Vivek __________________________________________________ Do You Yahoo!? Get Yahoo!
