Questions on IANA section (not an OSPF expert, so please excuse me if I
misunderstood something):
- Don't you have to register both LS types 9 and 10 somehow?
[HC]: LS types 9 and 10 are the existing types. No need to register them.

- And do the "Types for new TLVs in the new TTZ LSA" create a new
registry or is this an existing one?
[HC]: A new register needs to be created for "Types for new TLVs in the new TTZ LSA". In section “IANA Considerations”, the following changes have been proposed to and approved by IANA.

  IANA is to create and maintain a new registry:

  o OSPFv2 TTZ LSA TLVs

  Initial values for the registry are given below.

       Value         OSPFv2 TTZ LSA TLV Name    Definition
       -----         -----------------------    ----------
       0             Reserved
       1             TTZ ID TLV                 see section 6.2
       2             TTZ Router TLV             see section 6.3
       3             TTZ Options TLV            see section 6.4
       4-32767       Unassigned
       32768-65535   Reserved

  The future assignments are to be made through IETF Review.

Other minor comments:
- What's a DR? Please spell this out!
[HC]: DR is short for Designated Router. We will spell it out in the document.

- There is only little normative language used in this doc. Potentially
some more normative language could make things clearer. However I don't
have concrete proposals what to change and I believe the most important
parts are in normative language. So there is no urgent need to change
anything but maybe another check would be good to make sure normative
language is used where needed.
[HC]: We will have another check for this and make sure normative language is used wherever needed.
