The following errata report has been submitted for RFC3031, "Multiprotocol Label Switching Architecture". -------------------------------------- You may review the report below and at: http://www.rfc-editor.org/errata/eid5643 -------------------------------------- Type: Technical Reported by: Mark Smith <markzzzsmith@gmail.com> Section: Terminology Original Text ------------- <missing> Corrected Text -------------- label edge router - a router capable of accepting an unlabelled packet, and through MPLS processing, may MPLS encapsulate the packet by adding a label stack. Notes ----- I am doing some MPLS review. The book I'm using said an LER was an (RFC3031) MPLS edge node. I believed it was any router that could take unlabelled packets and label them, regardless of where the router was within the MPLS domain. (In other words, an MPLS router was not an LER if it would not MPLS label unlabelled packets and forward them.) I decided to check RFC3031 for a definition, and discovered there isn't a definition at all for "label edge router", or a match on any text that matches "label edge" or "LER". RFC6178 clarifies LER processing of IPv4 packets, and the general description of processing matches my understanding of what an LER is. However, it doesn't formally define an "label edge router" either, and I think an update to RFC3031 should be where "label edge router" is formally defined. Instructions: ------------- This erratum is currently posted as "Reported". If necessary, please use "Reply All" to discuss whether it should be verified or rejected. When a decision is reached, the verifying party can log in to change the status and edit the report, if necessary. -------------------------------------- RFC3031 (draft-ietf-mpls-arch-06) -------------------------------------- Title : Multiprotocol Label Switching Architecture Publication Date : January 2001 Author(s) : E.
