The RA contains a preference level... maybe that doesn't cut it if multiple routers are sending the same preference level, but presumably that would not happen in a well-tended network.
I point you to a fairly common Internet architecture artifact, the exchange point... dozens of routers sharing a common media for peering exchange.
And how do they discriminate now, with IPv4?

IPv4 has no concept of RA/ND. to make this construct work at all in IPv6, all participants have to turn -off- RA/ND to prevent one or more routers trying to impose their views of addressing on their neighbours. --bill
