In some embodiments, a network segment within a switch fabric system includes a layer-2 flood route database and a layer-3 switch interface operatively coupled to the flood route database. The flood route database is configured to store layer-2 flood route information associated with the network segment and contains information such as a set of port identifiers and a set of status indicators. Each port identifier identifies a particular port within the network segment and each status indicator is uniquely associated with a particular port identifier. The layer-3 switch interface associated with the network segment is automatically activated when the flood route database contains at least one valid port identifier and the status indicator associated with at least one port identifier is active. This can allow data traffic to flow between separate network segments within the switch fabric system.

Methods and apparatus for maintaining an integrated routing and bridging interface

In some embodiments, an apparatus includes a first network control entity configured to be implemented at a first edge device. The first network control entity is configured to receive a control packet from a peripheral processing device via a tunnel that is between the peripheral processing device and the first network control entity and that includes at least a portion within a second edge device. The first network control entity is configured to determine routing information associated with the peripheral processing device based on the control packet. The first network control entity is configured to send the routing information to a second network control entity such that the second network control entity routes a data unit addressed to the peripheral processing device to the second edge device without sending the data unit to the first edge device.
