On your router?

edit Less flippantly, what are you wanting to base the routing rule on? What's your ipv4 routing rule?

DSCP is allowed in ipv6.

Without nat, my understanding is the right way in v6 is to issue addresses of every network and then send a message to each end device asking it to use a specific ip address to route traffic and hope every client implements RFC 4191 in the right way.

There's a few options I'm aware of.

The "proper" way would be to get your own ASN and use BGP to route the traffic.

If you're wanting to use a secondary WAN link as a backup for when the other goes down you could have the backup link's LAN have a lower priority. (So I guess hope everything implements RFC 4191 like you said).

You can use NAT66/NPTv6 if you want (though it's icky I guess).

How are you doing it currently?

NAT66 is a thing.
