Abstract
Techniques for optimizing traffic flows via dynamic routing protocol (DRP) modifications when server virtualization is used with dynamic routing are provided. In one embodiment, a network device can determine that it is part of a system of network devices acting as a virtual router. The network device can then transmit, to a client device, a DRP control packet that includes an interface IP address of the network device and a virtual IP address of the virtual router. In a further embodiment, the client device can receive the DRP control packet and store the interface IP address and the virtual IP address in a routing database. At the time of computing routing entries based on the routing database, the client device can replace, in entries that identify the interface IP address as the next hop, the interface IP address with the virtual IP address.
