Abstract
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.
