Abstract
Redundant configuration and testing for flexible nodal layer 3 overlay of layer 2 traffic. A network deployed at a site includes a local network to carry layer 2 traffic, a pair of layer 3 tunnel instantiation devices in a failover configuration. Each layer 3 tunnel instantiation device encapsulates the layer 2 traffic into layer 3 traffic and forwards the layer 3 traffic to a network gateway using a configurable layer 3 tunnel. A virtual client on each layer 3 tunnel instantiation device sends simulated client traffic to the network gateway via the local network and a partner layer 3 tunnel instantiation device to check end-to-end operability of the local network, the partner layer 3 tunnel instantiation device, and the network gateway. A testing layer 3 tunnel instantiation device initiates an action with respect to the partner layer 3 tunnel instantiation device based on a response to the simulated client traffic.
