Document: http://www.ietf.org/id/draft-ietf-grow-ix-bgp-route-server-operations-03.txt Reviewer: Dan Romascanu Review Date: 9/18/14 IETF LC End Date: 9/22/14 IESG Telechat date: none Summary: A useful and very well written document, with a few minor issues that need clarification and fixes before publication Major issues: None Minor issues: 1. The reference [RS-ARCH] mentioned in 4.2.1.1 and 4.2.1.2 is not reachable (Error 404). As the understanding of the issues described in the two sections depend on this reference, a valid reference is required. 2. Section 4.2.1.3 uses the term 'flat layer 2 network' which has at least two meanings depending on the context or layer - either one VLAN space at the link layer (as to differentiate from Customer VLAN and Provider VLAN) or a bridged network with no routers between the bridged segments. Clarification is needed. 3. The usage of keywords is inconsistent in a few place. In 4.6.1 the 'should' in the second paragraph needs to be capitalized. In 4.6.3 we have a capitalized SHOULD, but then a non-capitalized 'may' for statements that both seem to describe requirements of the same level. 4. I am doubt that Section 4.7 is that useful. On one hand reliability of layer 2 forwarding is not in my opinion such a big issue, and measures can be taken a the link layer to improve it (use lags or redundant paths). Second the recommended mitigation (RFC 5881 BFD) is described as non-optimal, with no other alternative. I would just drop this section completely. Nits/editorial comments: 1. The English syntax of the second paragraph in the Abstract is broken. 2. In the introduction there is a mention of 'using shared Layer-2 networking media such as Ethernet'. Actually Ethernet is seldom used nowadays as a shared media, I would just recommend saying 'using data link layers protocols such as Ethernet' 3. In section 4.2 s/optimization technique is implemented/optimization technique that is implemented/
