  • Post-routed VLAN flooding
    Patent number: 9634927
    Abstract: A hierarchical lookup forwarding model to induce a Layer (L2) forwarding look up in a post-routed virtual local area network (VLAN). In one example, a line card of a networking device receives a packet for routing from a first virtual local VLAN to a second VLAN. The line card determines that the packet is associated with a host route having a corresponding incomplete Layer 3 (L3) adjacency. The line card steers the packet to a fabric module of the networking device. The fabric module performs an L2 lookup on the packet and floods the packet to one or more of line cards of the networking devices. The one or more line cards flood the packet on a plurality of external ports of the networking device.
