Hi Alia, Thanks for the review - you caught some rather subtle points.
From: OSPF <[email protected]<mailto:[email protected]>> on behalf of Alia Atlas <[email protected]<mailto:[email protected]>> Date: Thursday, June 9, 2016 at 3:57 PM To: OSPF WG List <[email protected]<mailto:[email protected]>> Subject: [OSPF] AD review of draft-ietf-ospf-transition-to-ospfv3-07 As is customary, I have done my AD review of draft-ietf-ospf-transition-to-ospfv3-07. First, I would like to thank the authors for their work on this document. It looks like very useful technology. I have a few minor questions below. I will put this into IETF Last Call as well while waiting for the authors to update the draft ASAP. That gives a chance of making it on to the June 30 telechat if the authors are responsive. Minor: 1) Sec 3.1: "If this is supported, the IPv4 data plane MUST resolve the layer-2 address using Address Resolution Protocol (ARP) on multi-access networks and point-to-point over LAN [RFC5309] for direct next-hops on different IPv4 subnets." I believe it is the IPv4 (i.e. layer-3) address to be resolved with ARP - not the layer-2 address. Ok - this text comes from me and I was viewing resolution from the standpoint of the “to” address family rather than the “from” address family. I agree the “from” address family is probably a more common characterization. 2) Sec 3.3: "If IPv4 transport, as specified herein, is used for IPv6 address families, virtual links cannot be supported. Hence, it is RECOMMENDED to use the IP transport matching the address family in OSPF routing domains requiring virtual links." From this section, I was expecting that "cannot" would be a "can". Did I miss something? Can you clarify further? The draft doesn’t address virtual link support in deployments where the address-family doesn’t match the transport. Hence, the text is correct as written. 3) Sec 1: 2nd to last paragraph: "In situations where the IPv6 deployment is a proper superset of the IPv4 deployment, it is expected that OSPFv3 would be transported over IPv6." I believe the "proper" should be removed. If the IPv6 deployment is exactly the same as the IPv4 deployment, then it is expected that OSPFv3 would be transported over IPv6. As it is,how the case of equal deployment is handled is unspecified. I agree. We will remove “proper". Thanks, Acee Thanks, Alia
