OK, I will replace “SHOULD ” with “MUST”. Thanks again Greg.

Best regards,

Hi Xiaohu,
thank you for your most expedient response and kind consideration of my 
comments.
I've just noticed typo in my own proposal s/There my/There may/.
And just one more question, why you propose to use SHOULD in "... the first 
occurrence SHOULD be processed ..." Would MUST be more appropriate here? Or you 
envision that in some circumstances this policy may be changed?

Regards,
Greg

Dear All,
yes/support (readability needs some work)

Couple nits:

  *   Introduction.

     *   Perhaps "Some networks use tunnels for a variety of reasons, such as:" 
may be re-worded as "There my be number of reasons why different types of 
tunneling technique has been used in networks, among these are:"
[Xiaohu] Will update it.

     *   "The ingress needs to select a type of tunnel which is supported by 
the egress." I think that the idea is to find match between set of tunnels 
supported by the ingress and the egress.
[Xiaohu] Yes. Will add more words to clarify it.

  *   Section 3

     *   s/Routers advertises/Routers advertise/
     *   It is stated that "The Encapsulation Capability TLV SHOULD NOT appear 
more than once within a given OSPF Router Information (RI) Opaque LSA." What 
happens when it does appear more than once? Discard LSA? TLV?

[Xiaohu] Thanks for pointing out this. How about adding the following text for 
clarification “If the Encapsulation Capability TLV appears more than once in an 
OSPF Router Information LSA, only the first occurrence SHOULD be processed and 
others MUST be ignored.”
Best regards,
Xiaohu

Greg
