RFC 4760, "Multiprotocol Extensions for BGP-4", January 2007

Source of RFC: idr (rtg)

Errata ID: 5120
Status: Held for Document Update
Type: Editorial
Publication Format(s) : TEXT

Reported By: Dale Worley
Date Reported: 2017-09-23

Section global says:

section 3:  ... each NLRI ... [2 occurrences]

section 5:  The Network Layer Reachability information is encoded as ...

It should say:

... each NLRI item ...

When the Subsequent Address Family Identifier field is set to one of
the values defined in this document (1 or 2), the NLRI field is encoded
as ...

Notes:

The text in section 3 makes it clear that the NLRI encoding in section 5 is only
specified for SAFI 1 and 2, but the text in section 5 does not state this. This tends
to cause readers to believe that section 5 applies to any SAFI. (See, e.g.,
draft-ietf-mpls-rfc3107bis.) (However, other RFCs do specify similar encoding structures
for some other SAFIs; see, e.g., RFC 3107.)

The wording "each NLRI" is incorrect, as NLRI is a field and there is only one of them in an UPDATE message.
