This draft has long been implemented by several vendors, particularly in support of VPN technologies.  The functionality covered in this draft does lead to long-lived stale routing that continues to be advertised in the BGP routing protocol, and related service protocol extensions that may use that state.  While such state is an item of concern, and likely will alarm reviewers who are being exposed to this mechanism for the first time, it is the desired behavior of the mechanism.

Document: draft-ietf-idr-long-lived-gr-02


This document (with intended status Standards Track) defines BGP Graceful
Restart udpates to keep stale routes longer, mainly for tunnel forwarding
infrastructure scenarios or scenarios where BGP is used to optimize management

Major issues: None

Minor issues: None

Nits/editorial comments:

Question 1: In the current version, only RFC 6368 is mentioned in Updates.
Would RFC 4724 also need to be updated?

Question 2: Would RFC6368 be in the normative reference?

Question 3: Is there a suggested default value for Long-lived Stale Time?
