Summary: The draft is almost ready for publication as Proposed Standard 
but there are some minor issues that need to be addressed as stated in 
my last call review. We are on the process of converging on the fixes by 
email.

* Section 2

* In the packet format described in Figure "OSPFv2 Extended Prefix 
Opaque LSA" the numbers 9, 10 and 11 are shown in a field. I think it 
would be better if these are replaced by the text "LS type" as it is the 
actual field. This will provide consistency with the rest of the figure. 
The following text can then describe the allowed LS types as 9,10, and 11.

s/differential/differentiate/

* Padding of TLVs. I am assuming that the TLVs are padded using zero 
octets. If so, please state it explicitly.

* Section 2.1.

* In the packet format the "Address Prefix" field is marked as variable 
length when it actually *is not*. It is always encoded as 32 bits long, 
right? If so please the "(variable)" designation needs to be removed
for the Address Prefix.

* Shouldn't there be some IANA instructions for further extensions to 
the Flags field in the OSPFv2 Extended Prefix TLV? Or is this field not 
expected to be extended?

* IANA Considerations

* The Opaque LSA Options types used by this document (7 & 8) seem to be 
wrongly entered into the IANA registry and are pointing to 
[draft-ietf-ospf-segment-routing-extensions] instead of this draft. It 
is probably worth taking this up during the IANA check.

Thanks
Suresh
