You have a rogue IPv6 router on your network. It's not a host problem.
It's along the lines of having a rogue DHCP server on your network but
faster propagation.
It needs to be tracked down and disabled.
You can use tcpdump (as root) to capture IPv6 RA and see who's doing it,
and what's being
tcpdump -e will show source and dest mac address.

RA guard is useful if your tcam capacity and or switching platform allows -

An older yet still a good read from Cisco on some IPv6 first hop security:
Hello, all!
I have Paradyne Bitstorm 2600 DSLAM, but no password. Is it possible to
reset this device to factory configuration? Manuals don't say much, only
specified way to restore factory settings assume logged in
administrator.
Thanks!
Thanks. I have already tried interrupting boot process. Booting up with
parameter 0x00020 (disable login security) don't seem affect outcome,
both serial and management ethernet still asks login.

Dear NANOGers,

Thanks for useful reply everyone!
As I mentioned - I applied quick temporary fix by stop broadcast from
router and clearing of routing table on servers. Will apply disabling of
autoconfig now.
