I will revise the patch in the next weeks and make outer IPv6 header
inherit Hop limit from Inner packet for the IPv6 case.

This is not an issue of seg6 RFCs, but rather generic ip6 in ip6
tunnel encapsulation.
Therefore, what t
Hi David,
SRv6 as defined in [1][2] does not mandate that the hop_limit of the
outer IPv6 header has to be copied from the inner packet.
The only thing that is mandatory is that the hop_limit of the inner
packet has to be decremented [3]. This complies with the specification
defined in the G
