I wonder if we could / should add a sentence or two related to the
address block noting that if an operator chooses to use other address
blocks for the SRv6 SIDs then they need to be extra careful about
configuring their edge filters to prevent leaks inwards or outwards?
Yours,

Hi Suresh,
Thanks for taking the comments into consideration. Snip to just two
points...
- Do we need to add some text on what happens if the address
block assigned by IANA is not used in the received IPv6 packet?
Dhruv: Any thoughts on this?
This block is not mandatory to use. The packet will be processed as
any other IPv6 packet would. Is there something specific you are
worried about?
- This text "This would be useful in identifying and potentially
filtering packets at the edges of the SR Domains as described in
Section 4.1.". But section 4.1 of this I-D does not have any
text for this! Do you mean some other document?
This is in reference to the following text in 4.1
" In this case, to allow the SR domain to fail closed, some form
of filtering based on the LOC part of the SRv6 SID is required as
relying purely on the presence of an SRH will not be sufficient.”
Please let me know if I can clarify this further.
Dhruv: I got confused because section 4.1 is meant to be only about
C-SID. My suggestion would be to avoid the reference and just put the
relevant sentence there for emphasis and clarity.
Sounds good. Will do.
Thanks
Suresh
