Abstract
Techniques are provided that enable a programmable network application-specific integrated circuit (ASIC) to switch over from L3 forwarding (i.e., routing) to L2 forwarding (i.e., bridging) an L3 network packet in certain scenarios, such as a scenario in which the packet fails to meet one or more criteria defined by a routing protocol. In various embodiments, this switchover (referred to as 'fallback to bridging') is achieved by leveraging programmable aspects of the ASIC's packet processing pipeline.
