Abstract
A method for network traffic forwarding using multi-virtual routing and forwarding instances forwarding lookups is provided. The method includes: receiving network traffic on an interface of a network device associated with a first virtual routing and forwarding instance (VRF) fallback policy specifying a first set of rules; making a first determination that the network traffic includes network traffic information matching the first set of rules; initiating execution of VRF lookups in a plurality of VRFs programmed in the network device to obtain a set of VRF lookup results; making a second determination, using the set of VRF lookup results and the first VRF fallback policy, that the network traffic is to be forwarded using a first VRF among the plurality of VRFs; and initiating, based on the second determination, forwarding of the network traffic using the first VRF.
