Hi WG,

We think this is useful to extend SRv6 for inter layer network optimization. And it can be applied to packet and optical integration. We would like to see this work moving forward.

Best regards,
Naihan

Hi Sasha,



Thank you for the reply.

In the underlay link scenario that our draft focuses on, protocols such as IGP or BGP are not running between the two end nodes of the underlay link, and the connection between them is an underlying link. We consider that it is different from the standard end.X behavior between L3 adjacencies as specified in RFC 8986. The forwarding behavior has its own particularities, so we think defining a new behavior should be better.



Best regards,

Liuyan

Hi Liyuan,

My apologies for a delayed response.

I have looked up Section 4.2 of RFC 8986 (that defines End.X behavior) and it contains the following statement:


When the End.X behavior is associated with a BGP Next-Hop, it is the SRv6 instantiation of the BGP peering segments [RFC8402].

I.e., End.X behavior can be decoupled from IGP adjacencies.

Hope this helps.


Regards,


Sasha
