Signaling Extensions Describes 3 signaling methods for inter-domain LSP : contiguous, nesting, stitching 2 new bits defined in LSP_ATTRIBUTES Flags TLV Contiguous LSP bit Used by head-end LSR of the inter-domain TE LSP Used to restrict the signaling method used by intermediate LSRs to be contiguous LSP Stitching desired bit Used by the head-end LSR of the LSP segment Used to request LSP stitching behavior Corresponding bit in RRO Attributes sub-object |
