Tom,
>I think the terminology being used in the draft might be making this
seem complicated than it actually is. AFAICT, SRv6 traditional mode is nothing
more than IP in IP encapsulation, so the requirement of the underlay is that it
>forwards IPv6 and intermediate nodes treat the traffic as
"normal IPv6 traffic". There is no segment routing involved, no extension
headers needed, and the only upgrade for the network is to support IPv6.
I am not sure that is the case. Please re-read Section 5.1 (and 5.1.3)
" This 1-for-1 mapping is
replicated here to replace the GTP encaps with the SRv6
encaps, while
not changing anything else."
