A network device may delegate a first prefix length to a primary WAN interface and delegate a second prefix length to a backup WAN interface. The network device may assign a first primary prefix and a first backup prefix to a first VLAN interface and may assign a second primary prefix and a second backup prefix to a second VLAN interface. The network device may provide egress traffic from host devices, connected to the first VLAN interface and to the second VLAN interface, to the primary WAN interface and without prefix translation, when the primary WAN interface is available. The network device may provide ingress traffic to the host devices, via the primary WAN interface and without prefix translation, when the primary WAN interface is available.

Systems and methods for supporting host devices with a single network address when multiple prefixes are delegated

Techniques for stateless address auto-configuration with support for multiple, different subnets are disclosed. In one embodiment, a method is disclosed comprising receiving, by a network device, a router solicitation (RS) message from a network node, generating, by the network device, a router advertisement (RA) message for use in determining the network node's network address, the RA message including a network address prefix and subnetting information, the subnetting information comprising a subnet address, a subnet address length and a subnet option type, and transmitting, by the network device, the RA message to the network node.

Stateless address auto-configuration with multiple subnet support method and apparatus

An Ethernet protocol data unit (PDU) over 5G service is provided. A network device in a core network stores addresses of advertised subnets, associated with multiple user equipment or customer premises equipment (UE/CPE) devices, in a subnet table that correlates a MAC address of each of the multiple UE/CPE devices to a subnet address. The network device receives an allocation and retention priority (ARP) request over a data link layer. The ARP request indicates an IP address for a target host of a data flow. The network device determines, based on the subnet table and the IP address, a MAC address of one UE/CPE device servicing the host address. The network device sends a directed ARP request to the UE/CPE device using the MAC address, receives in response a target MAC address for the target host, and sends a response to the ARP request with the target MAC address.
