This feature enables applying traffic policies on incoming traffic and redirecting the traffic to a nexthop other than the one the routing logic would choose. This essentially overrides the routing logic decision. If there is no rule matching the packet, the packet is sent to the routing logic to be routed.

Arista’s WAN routing solution comes with a suite of features. The network can spread across multiple geographical locations and make use of multiple types of service providers. One particular routing feature of this WAN network is called Adaptive virtual topology ( AVT ). Using AVT, the network operator can segment the physical topology into various virtual topologies based on certain constraints such as latency,  jitter or packet loss.
