Is there a standard that defines/recommends behavior for route injection of snooped DHCPv6-PD (or IA, I guess) assignments on routers running relay agents? That is, snooping or otherwise examining a relayed DHCPv6 response for a delegated prefix (or IA, if you want) and installing a quasi-static route toward the relevant next-hop based on the lifetime of the delegation. Typical redistribution can then be used to put it in IGP if you want.
This feature is usually found packed with the BNG/BRAS/broadband termination functionality. The keyword you need to search is "subscriber". The feaure pack is usually subject to additional licensing. Cisco, Juniper, Nokia/ALU, all have product ranges supporting that. Those being said, I'm interested in how that feature is supported on gear that is not "subscriber-aware" (you were talking about Arista), since generating routing information from relayed DHCP(v6) is a big/important part of the "subscriber management" functionality. -- R-A.F.
