Hello!
I have a NetBSD 9.1/amd64 machine running at an ISP under KVM. /var/log/messages is flooded with lines like
Apr 21 22:36:50 texel /netbsd: [ 789.0834680] in6_setscope: can't set scope for not loopback interface vioif0 and loopback address ::1
Apr 21 22:36:54 texel /netbsd: [ 793.0880294] in6_setscope: can't set scope for not loopback interface vioif0 and loopback address ::1

Apr 21 22:37:21 texel /netbsd: [ 820.0887825] in6_setscope: can't set scope for not loopback interface vioif0 and loopback address ::1
in such high volume, that the file is rotated every 3 to 5 hours.
I am mostly ignorant to everything IPv6, so I have no clue what that message means, and I was not able to find any enlightenment online. I was recently informed by my ISP about the following change:
"During this maintenance we will upgrade all our existing core routers as well as all core switches to a brand new platform built out of multiple Juniper MX204 core routers and Juniper QFX5120-32C core switches. With those devices our network will also become 100Gbps capable, making our network scalable and future ready."
Is this something I can fix from inside the OS? Is my ISP doing something strange or unexpected? Before I open a ticket with my ISP, I'd like to understand the problem in terms the ISP might know (they are very cooperative to allow customers to install NetBSD, but I guess they have no working experience with it).
The interface is configured like this:
$ ifconfig vioif0
vioif0: flags=0x8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
ec_capabilities=1<VLAN_MTU>
ec_enabled=0
address: 00:16:3e:b3:00:8a
inet
5.2.76.44/24 broadcast 5.2.76.255 flags 0x0
inet6 fe80::216:3eff:feb3:8a%vioif0/64 flags 0x0 scopeid 0x1
Thanks,
Joern
