Allow multiple subnets on gateway port for router
Currently, only a single subnet can be assigned to a router's gateway port (really, all ports whether an internal port or gateway port). This blueprint intends to provide a means of supporting a dual-stack arrangement on a router's gateway port by allowing both an IPv6- and an IPv4-based subnet to be associated with a router. We will disallow more that two subnets, and exclude allowing 2 IPv4 or 2 IPv6 subnets. IP address assignment is performed statically from the subnet as is currently performed.
A parallel Blueprint could be provided that could allow SLAAC generated IPv6 addresses on a gateway port for RA sent from upstream routers.
