how do these deployments look like? Because the granuality is generally
per broadcast link and I don't think we are talking about multiple
routers on one broadcast domain with the DHCP server doing the load
balancing?

You still need ND for tightly timed failover or you switch the MAC
address somewhere else, why is RA a bad thing here? (As you can
advertise the VRRP IP or VIP in it, for instance).

Or are you actually about the need for routers to send out the packets
on a large number of interfaces? It'd be nice to see something stronger
than "wouldn't work".

Kind regards
