Hello,



I have been selected as the Routing Directorate QA reviewer for
draft-ietf-ospf-routable-ip-address-00.



The Routing Directorate QA reviews are intended to be a support to improve the
quality of RTG Area documents as they pass through the IETF process. This is
the QA review just after WG adoption.



Summary



This draft defines a useful extension to OSPF to allow routers in other areas
to be able to associate reachable addresses with a router which supports a

particular capability. I do not foresee any major hurdles in this document
progressing to become an RFC.



Comments



It would be beneficial to explain why the routable address information only
needs to be flooded with domain-scope

(i.e. explain how routers in the area already have this information).



I suspect the security folks will likely point to the dangers of advertising
local node addresses domain wide –

which may make it easier for a node in one area to be targeted from another
area. The security section should

anticipate this by referencing the various OSPF authentication RFCs as the
means to protect this information.



Major Issues



No major issues found.



Minor Issues



The IANA Comsiderations section should refer to the OSPF Router Information
(RI) TLVs Registry defined by [RFC4970].



Nits



Abstract: Last sentence

   s/the OSPF/the term OSPF



Introduction: First paragraph

   " propagated to another area, those routers in the latter area need..."



The sentence should end after "area" and a new sentence begin with "Those".



Introduction: Last sentence

   s/the OSPF/the term OSPF



Section 3: penultimate sentence

The phrase



  "within the body of the corresponding RI Opaque LSA"



can be removed. It repeats the first sentence of the paragraph and does not
match the equivalent text in Section 4.
