Reviewer: Dan Romascanu Review result: Has Issues This document describes two techniques that improve the scale of deployment of RSVP-TE LSPs. Here are a few issues operations related issues that I recommend to address: 1. The document is titled 'Implementation Recommendations'. As such an RFC 5706 review does not apply. Yet, it aims Standards Track status, and includes a number of protocol extensions and registry definitions. The document mixes protocol extensions, implementation recommendations and recommendations of configuration in deployment. Maybe the title does not really reflect the current content? 2. Section 2.1 includes a number of " RFC2961 Specific" Recommendations. However, it is not clear why these are recommendations. For example, reading RFC 2961, nothing indicates that support for RSVP Refresh Overhead Reduction extensions or the receipt of any RSVP Refresh Overhead Reduction message (as specified in Section 2 of RFC2961) are optional. Moreover, RFC 2961 is also Standards Track. So why do we need 'recommendations' to support sections of a standards-track document? Would not just mentioning RFC 2961 compliance be sufficient? 3. From an operational point of view it is unclear how the recommendations to set the default periodic retransmission interval defined in section 2.1.3 and the configurable refresh interval and the configurable node hello interval defined in section 2.2 are supposed to be implemented. Is this a one time initialization required for every capable node? If so, the capability needs to be confirmed before the re-configuration. This needs to be done for every node? How, if scale is a concern?
