Be ye not afraid. I have reviewed this document as part of the Operational directorate's ongoing effort to review all IETF documents being processed by the IESG. These comments were written primarily for the benefit of the operational area directors. Document editors and WG chairs should treat these comments just like any other last call comments. Document: draft-ietf-l2vpn-ipls-14 Reviewer: Warren Kumari Summary: Looks good, with nits. Note: The document states: "At this point, no further action is planned to update this document and is published simply as a historic record of the ideas." AFAICT, this means that many of the OpsDir review checklist things do no apply... W Nits: Abstract. O: This became non-issue P: This became a non-issue 2.0, Number 5 O: Following rules are observed when processing ARP packets, P: The following rules [...] 2.0, Number 8, first bullet O: In VPLS, MAC entries are placed in the FIB P: Spell out FIB; first use 2.1 Terminology section, definitions don't have consistent indentation (some are hanging indent, some no indent, etc.) 9.3 O: It is important to note that the frames sent to the control plane is applied stricter rate limiting criteria to avoid overwhelming the control plane under adverse conditions such as Denial Of Service attack. P: It is important to note that stricter rate-limiting criteria is applied to frames sent to the control plane, in order to avoid overwhelming it under adverse conditions such as a Denial of Service attack. 9.3 O: Also, a caution must be used such that only link local multicasts and broadcast IP packets are sent to control plane. P: Also, caution must be used so that only link local [...] 9.4 O: is sent to the control plane for the CE discovery purposes. P: is sent to the control plane for CE discovery purposes. 9.5.1 O: which results into a copy P: which results in a copy 9.5.4 O: The multicast RA and RS Ethernet frames are replicated to using the Send Multicast Replication Tree as described in section 6.3. P: -- "replicated to using" is awkward, and I'm not sure what is meant here. 9.6 O: An IP frame received over a unicast pseudowire is prepended with a MAC header before transmitting it on the appropriate ACs) P: -- No opening parentheses; delete the ) after ACs 11.0 O: Note however that some P: Note, however, that some 12.0 O: The selection of appropriate multiplexing/demultiplexing scheme is the subject of future study. P: Either "an appropriate" [...] or change "scheme" to "schemes" 14.1 O: In nutshell, P: In a nutshell, 15.0 O: In addition, VMs tendancy P: In addition, VM's tendency O: The IPLS solution facilitates VM mobility by way of PE closest to the new location signaling the MAC address to all remote peers. P: [...] facilitates VM mobility by the PE closest to [...] -- I don't think the execution is relevant when it was obviously a bad idea in the first place. This is like putting rabid weasels in your pants, and later expressing regret at having chosen those particular rabid weasels and that pair of pants. ---maf
