But where are all these horrifically unreliable tunnels?
6to4 is one example.I'd say since PMTUD is too often broken on IPv4 (if the tunneling routers even react properly to PMTUD need-to-frag messages for their tunnel packets) in combination with some ISPs supporting jumbo frames internally, makes a lot of tunneling work badly.
So you might use tunnel broker tunnels that handle tunnel packet fragmentation for 1500 byte payload over 1500 byte infrastructure and that makes you feel they are reliable.
My tunnels to my home where I run routing protocol over the tunnels to two separate tunnel routers at the ISP end (I control all endpoints) plus running ipv6 MTU 1400 in my home to avoid PTMUD for all TCP connections is also a very reliable setup, but I'd rather have native IPv6 and 1500 MTU end-to-end.
