No objection.

Scudder; idr@ietf. org Subject: Re: [Idr] [Editorial Errata Reported] RFC4271 (6498) Hi! rfc4271 defines “discretionary” as simply the fact that the attribute may or may not be included in all UPDATE messages. From that point of view, the type is well-known discretionary. However, using “discretionary” with a required action can also cause confusion. I think the report is valid — but I also don’t think it should be marked as Verified. Instead, it should be marked as “Hold for Document Update”. Does anyone object to this classification? Thanks! Alvaro.

Corrected Text -------------- LOCAL_PREF is a well-known discretionary attribute that SHALL be included in all UPDATE messages that a given BGP speaker sends to other internal peers. Notes ----- It is unclear from the text to which of the four path attribute categories LOCAL_PREF belongs. There was even submitted an errata to create a fifth category for this attribute, but it is clear from the definition of the categories, that this attribute is well known discretionary. All routers must be capable of sending or receiving the LOCAL_PREF attribute, however it is up to a routers discretion whether to include that attribute in an UPDATE message.
