Hey Silvia,
thanks a lot for the insight! I did not expect this answer when asking this

I am currently doing my master thesis [0] about IPv6 in fully programmable
P4 switches (my hardware platform will be Barefoot

try a tracepath6, you likely have a 1500 MTUand yeah then it "works", not when
PtB gets involved though.
ICMPv6 (and other packets, 40% on one hop), are obviously being dropped...

Good morning,
is anyone from sbb.ch reading here?
https://sbb.ch does not load on IPv6 for us.
It seems that packets > 1420 bytes are dropped inside the SBB network,
Local PMTU / fragmentation seems to work, my local outgoing
MTU is 1420. MTR below.
Best,
Nico
