To clarify: someone is advertising themselves as a default router on the IETF network. Who presumably isn't the real IPv6 router.
Typically this happens with Windows machines with Internet sharing and 6to4 enabled.
As these RAs are advertised with low preference it doesn't disturb the network too much. Apart from the fact that all traffic to other 6to4 sites are routes through someone else's laptop...

Replying to xzhao@…:
we also have acl configured on switch to block RA broadcasting to whole network. yes, it may cause problems but impacts are limited to a certain level, that is probably the best we can do.
thanks,
