Subject: [Lsr] OSPF TE Link Local TLV

Hi,

I have question regarding RFC 4203, Section 3. That section introduces 
top-level TLV type 4 (Link Local TLV) and, at the same time, describes Link 
Local Identifier TLV. I guess that latter in fact is Sub-TLV of Link Local TLV. 
Also, IANA Considerations section doesn't mention that Sub-TLV, but only 
introduction of Link Local TLV. IANA has no corresponding registry  - "Types 
for Sub-TLVs of Link Local TLV (Value 4)".

I believe this example is actually wrong and section 3 should refer to the 
top-level Link TLV (value 2) defined in RFC 3630. The Link Local Identifier is 
the one advertised in Link Local/Remote Identifiers Sub-TLV (type 11) defined 
in RFC 4203 section 1.1.

Hope this helps,
Acee

Thanks in advance.

Best regards,
Alexander Okonnikov
