IPv6 gore

IPv6 gore

Gateway

$ cat /etc/rad.conf
interface vlan42 {
no auto prefix
prefix 2001:db8::42/128
}

OpenBSD Host, running slaacd(8)

$ ifconfig vio0 inet6
inet6 2001:db8::42 prefixlen 128 autoconf pltime 2699 vltime 5399

A triumph in modern igoring.

I always suspected that this would work on OpenBSD, we intentionally wrote it this way, but as far as I know, nobody every tried it.

Btw. don't tell the occupants of the IETF 6man working group. They will probably blow a gasket, go feral and come after me.
