Hi , Generalized Signaling RFC 3471 , says about component Links "For types 4 and 5, the Interface ID indicates a bundled component link. The special value 0xFFFFFFFF can be used to indicate the same label is to be valid across all component links." How this value 0xFFFFFFFF is supposed to get used ? How will one identify component link if value in Interface Id is 0xFFFFFFFF ? Regards , Manoj
