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.
