hey,
If you use source-based/policy routing (linux ipv6 fib subtree feature)
you could segment the subnet further and let the default gateway emit
redirects if the subtree has a default gateway which is on-link for
the clients.
In case they don't react I guess this will pollute your network with further
traffic (or you just drop the traffic by other mechanism).
Hm, you should not drop the traffic, otherwise icmp rate limiting would create
blackholes.
Thanks for thinking along. In reality I was talking about residential
broadband setup so HGWs from many vendors and major vendors for routers.
