Hi GROW, Following the discussion and comments on and off the list over the last few weeks, I have made some modifications to some of the discussion within this draft.
Particularly, the changes are: - As per Wes George's suggestion (and Sue Hares' request), added a statement that future updates to the BGP specification should define the category of error, and expected error handling class within which errors in each attribute fall. - Updated the discussion of scaling considerations for both automated response to semantic errors, and the behaviour during repeated critical errors, as per the discussion on the GROW list. I think that this captures the conclusions that were reached, but comments are welcome. - Some minor changes to wording and bringing drafts referenced in the informational references in line with the current drafts (mainly in light of a number of these drafts being adopted as IDR working group items). Chris, Peter - I would like to request that this version of the draft is submitted for WGLC as I think this addresses all the outstanding comments both from the Paris meeting, and that I have received via on- and off-list mail. Many thanks in advance for any comments and/or LC initiation! Kind regards, r.
